Trimble has built a new suite of collaboration tools directly into the heart of SketchUp for Desktop, alongside improvements to documentation, site context, and visualisation.

The latest release of the popular push/pull 3D modelling software introduces private sharing control, in-app commenting, and real-time viewing, allowing designers to collect feedback from clients and stakeholders without leaving the SketchUp environment.

“Great designs are shaped by conversation, iteration and shared insight,” said Sandra Winstead, senior director of product management, architecture and design at Trimble. “Rather than jumping between email threads or third-party tools to hold conversations, collaborate and make design decisions, we’ve built collaboration directly into SketchUp.”

With these new tools, designers can securely share models with selected stakeholders, controlling who can view and comment. Feedback is attached directly to 3D geometry, ensuring comments are linked to the right part of the model.

All collaborators see updates instantly, creating what Trimble describes as a shared space for real-time design conversations. Cursor and camera tracking features also allow clients and colleagues to follow along during live presentations.

Elsewhere, SketchUp now includes professional 2D drafting tools in LayOut, the companion application used for presentations and documentation.
According to Trimble, users gain access to more intuitive and precise drawing features for common documentation tasks, along with new scrapbooks offering standard architectural graphics such as doors and windows for scaled 2D composition.

An enhanced DWG export workflow helps ensure that SketchUp geometry and Tags are accurately preserved when transferring designs from 3D SketchUp into 2D CAD or BIM tools.

Trimble has also upgraded Scan Essentials, the SketchUp plug-in for turning point cloud data into 3D models. The latest release makes it easier to incorporate existing buildings into terrain as pre-built 3D geometry, supporting more accurate visualisation, climate analysis, and site planning.

SketchUp’s visualisation capabilities have been further refined, offering greater stylistic control and a broader set of rendering options, including Color Ambient Occlusion, Ambient Occlusion Scale Multiplier, and Invert Roughness.

Finally, for AI-assisted rendering, a new Diffusion Labs update delivers higher-fidelity imagery and greater creative control over AI-generated imagery.

Trimble SketchUp 2025 features better interoperability with Revit and IFC, and new visualisation capabilities, including photorealistic materials and environment lighting options.

To improve interoperability the 3D modelling software now includes more predictable IFC roundtrips, greater control over which Revit elements and 3D views are imported, and improved support for photorealistic materials when exporting USD and glTF file formats.

“The IFC import feature is incredible,” said Lucas Grolla, architect and owner of Grolla Arquitetura. “It has greatly improved the coordination of different project models with the architectural design. Plus, the new material editor and HDRI styles open up countless possibilities for the visual representation of projects.”

According to Trimble, the new visualisation features enable designers to apply photorealistic materials, turn on environment lighting and see how they interact in real time without hitting a ‘render’ button or waiting to see changes.

For enhanced environments, 360-degree HDRI or EXR image files now act as a light source, reflecting off photoreal materials. Meanwhile, dynamic materials are said to more accurately convey texture and represent how real-world materials absorb and reflect light, with a view to producing richer, more realistic visuals within SketchUp. Finally, the introduction of ambient occlusion adds visual emphasis to corners and edges, adding perceived depth and realism with or without having materials applied.

“Accessing high-quality, realistic materials directly within the platform has made it so much easier to quickly present designs that resonate with clients,” said Kate Hatherell, director of The Interior Designers Hub. “This feature is a game changer for accelerating workflows, and I’m excited to see how it continues to evolve.”

Elsewhere, LayOut, a tool for creating documents from SketchUp models, has been updated to provide a user experience more consistent with SketchUp. 3D Warehouse, a vast repository of 3D models, also now offers curated photoreal materials, environments and configurable 3D assets in the SketchUp content library.

BIM software startup, Skema, has introduced a new integration with SketchUp aimed at helping designers make use of SketchUp’s early-stage design capabilities to drive BIM workflows and Revit deliverables.

The integration allows designers to start massing in SketchUp, move into Skema for ‘block-and-stack’ planning, and return to SketchUp for design exploration of facades, rendering, energy use, lighting, and more.

According to the developers, Skema’s ‘BIM in Minutes’ feature allows users to move their designs into Revit at the push of a button, ready for construction documentation.

“We’re working to bridge the gap between SketchUp and a firm’s existing BIM workflows within Revit,” said Richard Harpham, co-founder of Skema. “The new Skema for SketchUp extension empowers architects to transform their initial design concepts into precise, data-rich BIM models faster—reducing rework, data loss, and coding.”

Skema for SketchUp is available now for $349/year.

Meanwhile, to learn more about Skema, watch the following presentations from AEC Magazine’s NXT BLD / NXT DEV conferences

Trimble gave attendees of its annual Trimble Dimensions user conference an inside look at the company’s latest initiatives to incorporate AI into AEC workflows, including visualisation, reality capture, project management and takeoff.

For visualisation, SketchUp Diffusion [Labs] is a generative AI-powered tool, available as part of the SketchUp Labs public beta program, that allows architects and designers to generate visualisations in seconds based on the active SketchUp viewport and a natural language text prompt or preset style.

Learn more about Diffusion models in this guide for AEC professionals).

For project management, ProjectSight includes a new drawing import feature that uses AI to read and extract critical drawing information for improved project visualisation.

For takeoff, Trimble LiveCount uses new AI functionality to automatically detect and count thousands of symbols on construction drawings with a view to saving contractors from hours of manual, repetitive and time-consuming tasks.

Trimble LiveCount includes the ability to automatically detect and count different types of receptacles and switches — the most common electrical items on drawings, helping electrical contractors create estimates faster, easier and more accurately.

Trimble LiveCount AI functionality is available in the Trimble Accubid Anywhere (named user) and Hosted Accubid Classic Estimating Essentials subscriptions.

Meanwhile, Trimble has announced that SketchUp has surpassed one million active subscribers.

SketchUp 2024, the latest release of the push pull modeller commonly used for architectural concept design, has a brand-new graphics engine designed to increase 3D performance, and realism through Ambient Occlusion.

The new graphics engine is reported to allow users to experience both an increase in frames-per-second while orbiting models and better handling and responsiveness.

According to the developers, internal testing has shown that the most common configurations are about 2.4x faster than SketchUp’s ‘classic’ graphics engine, and for higher-end configurations, there’s an improvement of 8.4x faster, with some cases even higher.

The ‘classic’ SketchUp graphics engine is still available for those with older hardware configurations.

The new graphics engine also supports Ambient Occlusion, a viewing style designed to emphasise edges and faces, adding perceived depth to models, increasing realism in SketchUp viewport.

Users can select pre-built Ambient Occlusion Styles in the Styles panel or tweak the Ambient Occlusion settings sliders and create their own new Styles

“Ambient Occlusion makes the core tool no longer look like just a “sketch,” said one beta tester. “Before, I needed to always consider rendering it in some other app before presenting my model. I no longer have to worry about that — 95% of what we need to convey is ready to go in SketchUp.”

“Ambient Occlusion is the single most exciting feature in recent years! I got no work done this afternoon playing with it,” said Joe Calvin, lead architect. “Most of my models are achromatic, so this makes them pop, particularly architectural interiors.”

SketchUp for iPad can now take advantage of the iPad Pro’s LiDAR scanner to capture scans of buildings and transform the data it into ‘clean, organised 3D geometry’ as a starting point for conceptual design.

The new Scan-to-Design [Labs] feature uses a combination of Canvas scan technology, Apple RoomPlan technology and Trimble technology to capture interior and exterior spaces. Designers simply scan a room as if they were painting the walls, and choose whether to output textured 3D meshes that are created with Canvas scanning technology or create ‘simplified, untextured planes’ using Apple’s RoomPlan technology –or both.

Once the data has been captured designers can use SketchUp for iPad’s modelling tools to quickly visualize and iterate design options in 3D. For feedback, clients and other collaborators can use Apple Pencil to mark up the model. They can also immerse themselves in the design using augmented reality (AR).

For collaboration, designers can also use Trimble Connect to share designs in the cloud, allowing them to manage projects and teams and invite new collaborators to view 3D models using easy-to-share links.

“Designers want to capture complete as-built conditions quickly and easily without having to switch between multiple tools, and they need to share their conceptual designs with clients in a way that builds both excitement and trust,” said Mike Tadros, director of product management at Trimble.

“Scan-to-Design solves those needs by empowering designers to quickly capture a holistic view of a job site and provides a starting point for creating beautiful conceptual designs that can easily be shared with a client for immediate feedback.”

“Today’s designers are increasingly taxed with having to capture an enormous amount of detail, come up with beautiful designs that will ‘wow’ their clients, and communicate that in a way that easily facilitates feedback,” said Sumele Adelana, senior product marketing manager for Trimble SketchUp.

“Scan-to-Design drastically streamlines that workflow while also making it more visually appealing by enabling designers to easily capture, design, and collaborate – all in one app.”

Scan-to-Design is currently available as part of the SketchUp Labs Program, a public beta that allows SketchUp subscribers to try new features and provide feedback.

SketchUp for iPad review

The post SketchUp for iPad embraces reality capture appeared first on AEC Magazine.

Architects are known to dream big. They design to inspire social change and a greener future, but it’s a contractor’s job to build those big ideas. Understanding how to move from concept to concrete pour is a creative challenge in itself. If architects are pushing the envelope design-wise, it means the contractors they work with have to push the envelope on what can be built, asking: Is the design structurally sound? How do we coordinate multidisciplinary teams efficiently? What is the best way to pour concrete for complex, organic shapes?

Construction professionals often want to try new technology workflows, but they lack the time and budget — and don’t want the owner to think they’ve wasted resources on experimentation. With little margin in the construction industry to support creativity, finding space for exploration and play within real-world deadlines and budget constraints is still possible.

Owner of RDF Consulting Services and consultant for Turner Construction, Renzo di Furia, has found that prototyping using student resources, working in 3D across project phases and developing technology ecosystems for communication helps construction teams discover innovative ways to build.

Prototype, then iterate again and again

Construction professionals must constantly learn new technologies to save time and build sustainably, but often they are stuck using old processes because it’s hard to pivot. Applied research solutions are a long-term investment that can pay off for the current project but, more importantly, can be used for future projects and scaled for large or small builds.

Working with undergraduate and graduate programs at the University of Washington, Renzo has found a way to experiment with cost-effective construction technology that gives students real world career experience. He understands that if his teams don’t continually innovate, others will, and the bottom line will suffer.

“The advancements that NASA developed to get to space created an innovative environment that has fielded a whole generation of technology,” said di Furia. “We need a similar revolution in the building industry. But it’s not just about investing in the latest technology; it’s applying technology to real problems, prototyping to create a repeatable process, and implementing adoption and learning on a larger scale.”

Students are the perfect group to test new construction technology because most grew up with smartphones and computers within easy reach; picking up new tech is second nature.

The global climate crisis will impact their generation the most, so they are motivated to find technology solutions that will reduce waste and shape a more sustainable future. Because students don’t have to unlearn outdated processes — those ways of doing things that have been around forever and are now second nature for many construction professionals — they may be more likely to embrace innovative solutions.

A catalyst for change

Professor Carrie Dossick, the associate dean of research at the University of Washington, understands the untapped potential of students. She created an educational program, the Applied Research Consortium (ARC), that benefits both students’ careers and construction professionals’ bottom line. Renzo heard about the program and immediately joined as an industry member and contributor.

Students, Turner Construction, and the Sydney Opera House

The theory that putting students together with professionals would spark workflow innovation was put to the test in 2018. Turner Construction had just bought a new CNC machine and needed a team to try different building methods before using it on a large job with high stakes consequences.

At the time, Renzo worked in Turner’s virtual design and construction (VDC) department. He collaborated with the university students to develop a better process for prefabricating formwork using the CNC machine. The team decided to recreate the famed Sydney Opera House using modern construction methods.

The performance art centre, built in Sydney, Australia, started construction in 1959 and opened in 1973 and is known worldwide for its iconic white ceramic tiled sails. The precast ribs and roof panels were all manufactured in an on-site factory, a very advanced concrete operation method for its time. Less well-known is that the construction was inundated with problems from the start. The podium structure on which the shells rest was constructed many years before finalising the structural design, which required most shell-supporting columns to be reinforced down to bedrock and caused considerable construction delays.

“There wasn’t a how-to manual that showed us how to make what we needed with our CNC machine,” said DiFuria. “It was a lot of trial and error. There are many, many complexities. We learned while tearing the machine apart and putting it back together.”

Renzo and the students began their research by reviewing the building process and finding a way to recreate it with the CNC machine. They studied the 2D construction drawings of the Opera House and translated them into a 3D model. From there, the team modelled the rebar and the formwork. Once the 3D model was created, the team successfully used the CNC machine to build the forms and pour several 1:4 scale prefabricated rib elements.

The team developed a model-based, digital prefabrication workflow from their research project. This type of work is complex and previously required high labour investments for low dollar returns. Working through how to use the CNC machine alongside other process improvements made pouring concrete more effective and helped the work fit into a manageable construction schedule. These advancements won several industry awards, including the AGC’s Build Washington Excellence in Innovation in 2018.

Building momentum

While at Turner Construction, Renzo worked with the ARC to develop a continuing education course called Virtual Modelling for Digital Fabrication, which aims to give students an even deeper dive into modelling for digital fabrication. It touches on core elements of the digital fabrication toolbox: laser scanning for reality capture, referencing historical documents, advanced model building, file formatting for laser cutting, CNC routing, and 3D printing. With the development of this curriculum, current and future students can practice real-life, advanced model-building and problem-solving for new prefabrication technologies as they come along.

Using Trimble SketchUp for 3D modelling and Scan Essentials to import point clouds, students taking the course learn how to model a historic building. This course is ideal for students who want to learn more about design-build management or want to learn practical skills that could help them move into a related role.

SketchUp provides software for students to use and instructional videos. This program is another positive outcome of partnering with the University of Washington and supports Renzo’s assertion that creating an authentic, research forward environment must include both learning and teaching.

Applied research

The learnings discovered on the re-modelling and quarter-scale casting of the Sydney Opera House ribs have since been applied to many different projects, including the large-scale renovation of, and addition to, the Seattle Aquarium. Constructed in 1977, Seattle’s central waterfront Aquarium has become a wellknown destination for locals and tourists.

The Aquarium’s expansion will accommodate a larger marine habitat to meet current and future demands. Turner Construction was hired as the primary contractor, and in November 2022, the company completed a more than 23 consecutive-hour concrete pour for the new habitat.

“Everything we learned exploring the Sydney Opera House, which was about a two year discovery period, we applied to the Seattle Aquarium: how we modelled the structure, how we modelled the rebar, how we approached the formwork, and more,” said di Furia.

Part of what made the habitat so tricky to build was its organic shape that draws inspiration from the ocean and offers visitors striking views of its aquatic inhabitants. Since the planned habitat was enormous, the team knew rebar constructability would be challenging. The unique, fabrication level modelling workflow was developed by Turner in-house. The structure has a two-foot-thick, curved concrete wall, 355 tonnes of rebar, and 680 cubic yards of concrete, which is about four times the rebar used on a typical core, according to Turner. The concrete form liners were constructed using structural foam with a fibreglass coating.

The foam was carved directly from the 3D model using large industrial CNC machinery. Formwork for window openings, the circular stairways, and the dramatic entrance oculus was produced using digital fabrication methods in Turner’s fab shop.

The previous research that students and Turner had done on parametrically modelling complex, organic concrete geometry, rebar constructability, and digitally fabricating formwork using CNC machines helped the team tackle the unique build for the Seattle Aquarium, saving significant time and money.

Adopting 3D from start to finish

One of the challenges in construction — and one of the reasons it’s so expensive — is the job teams can be massive, and there is a lot of information to process. You’ll often hear about siloing problems between architects, contractors, and owners. What’s less common is to hear about the silos within construction teams.

You could have fifty trades on a job site, each needing materials and equipment at a specific time. Valuable time and resources are wasted if these needs are not coordinated effectively.

“Building a sound 3D model that you can use throughout the design and construction process takes quite a bit of practice and dedication — a little bit like learning to play a musical instrument well,” said di Furia.

Renzo and Turner leveraged data in a 3D environment for the Seattle Aquarium project to improve collaboration across teams. It’s now the first project that Turner has done using 100% model-based communication from start to finish. Renzo and the Turner team used a SketchUp model with hundreds of scenes for site planning.

Later in the construction process, they pulled all the material amounts from measurements in the 3D models of the habitat, which included a 3D model for concrete, wood, and rebar.

The habitat was first mocked up with a physical foam model — carved with a giant CNC machine — a later iteration of the process the students developed studying the Sydney Opera House.

“For the Seattle Aquarium, the complexities of the design pushed the site management to adopt a complete 3D workflow, which broke down information silos and allowed any puzzles to be solved by a much more unified team,” said di Furia. “The ability to problem-solve effectively with a large, disparate group is rare and demonstrates the enormous value of a true 3D process.”

Having a 3D model updated from the beginning of the process through construction kept an open line of communication with all stakeholders. Turner’s team met with the architects and other disciplines once a week to review the 3D model and solve any challenges.

An interconnected tech ecosystem

Interoperability between design software was just as important as communication between people on the project. The team used Trimble Connect, a cloud-based common data environment (CDE) and collaboration platform created to keep everyone connected with synced model versions.

In addition to Trimble Connect, the team used SketchUp for 3D modelling, LayOut for generating 2D documents, Tekla for structural design, Trimble Total Stations and Trimble Laser Scanning Solutions for surveying, Revit for detailed construction documents, and more.

“We began our VDC journey years ago by coordinating MEP systems,” said di Furia. “We then took those lessons and applied them to our self-performed concrete operations. During that discovery process, we realised that the true critical path of any construction project is information management. I’ve since been prototyping an improved structural-centric workflow system that increases quality control dramatically and can be applied to any project, large or small.”

For the Seattle Aquarium, the complexities of the design pushed the site management to adopt a complete 3D workflow, which broke down information silos and allowed any puzzles to be solved by a much more unified team

Using the right technology at the right time levelled up Turner’s modelling and coordination for the Seattle Aquarium, strengthening the quality control processes and helping manage all the information shared throughout the design and construction process.

Structure-centric systems

The construction industry is moving into a new era of collaboration, and there will be new technologies and processes to adopt. Renzo believes moving toward structure-centric systems will improve coordination and bring model information together.

“ln all the years that I’ve been doing this [VDC Management], we start with MEP coordination and then apply that to our self-performed concrete operation,” said di Furia. “I believe there’s a better way; I’ve prototyped a structure-centric workflow system to help bring data and disciplines together, following one centralised structural model.”

Creativity and construction go hand-in-hand

The construction industry still has enormous challenges with workflow disconnects, finding ways to apply new technology, and teaching its adoption across teams — challenges that need to be overcome to build a better and greener future.

Construction professionals, it’s time to show how creative you can get when building. Contact your local university to connect with students looking for their next thesis topic.

Research and replicate innovative solutions on smaller projects first, and then combine what you learn with advanced 3D workflows and intelligent technology to build projects more quickly and efficiently. All this will inspire a culture of learning in your company that reduces waste and is better for the environment. Let’s show the next generation of engineers, contractors, and consultants that thinking of outside-the-box solutions is just as crucial for future builders as it is for future designers.

Trimble has launched SketchUp Viewer for Meta Quest, for an immersive way to view and present 3D SketchUp models in VR. The software enables AEC professionals with a Meta Quest 2, Meta Quest Pro or Meta Quest 3 headset to engage colleagues and clients in immersive design reviews for more informed decision-making and collaboration.

“Meta has been at the forefront of growing VR adoption by making the technology easy to use, accessible and affordable,” said Chris Cronin, vice president and general manager of Trimble SketchUp.

“Collaborating with Meta to create SketchUp Viewer for Meta Quest is an important milestone toward making it easier for design and AEC professionals to tap into the power of VR as a rich, immersive way to experience, share and collaborate on SketchUp models.”

In addition to native SketchUp tools, SketchUp Viewer for Quest includes features, such as tabletop and presentation modes, that offer architects and designers multiple ways to present their designs.

With tabletop mode, users can walk around the SketchUp model and view the design as a virtual scale model. Presentation mode can be used to curate a client’s virtual walkthrough, complete with a simple user interface and easy-to-use controls.

“We’re already seeing the value of virtual reality in architecture and design, whether it’s exploring ideas, solving problems or showcasing designs in the best possible light,” said Jamie Keane, director of product management at Meta. “We believe the combination of SketchUp and Meta Quest will create new opportunities for connection and collaboration.”

SketchUp Viewer is free to download and explore the demo files, but needs an active SketchUp Pro or SketchUp Studio subscription to view your own models.

Trimble SketchUp’s 3D Warehouse, the free 3D model library, has made it easier to find models, through a new visually-driven search function called Image Search.

Users can now take a photo of an object or drop and drag an existing image into the 3D Warehouse’s search bar, and AI will sift through millions of pre-built models to find matches. The new feature is designed to help architects and designers more easily specify new products for their designs.

“3D Warehouse used to be entirely based on keyword search, where you had to type in exactly what you were looking for in order to generate the right match,” said Steve Guzman, product manager for 3D Warehouse.

“3D Warehouse Image Search eliminates that requirement, allowing users to overcome language barriers and incorrect search queries by matching images with models.

“Now, designers can more easily source 3D models or find alternatives for their clients who are often looking for very specific objects to incorporate into their designs.”

As well as user-generated models, Image Search results include real-world objects from building product manufacturers and parametrically configurable objects.

On top of Image Search, users can now easily search, filter, and download materials and texture swatches by simply typing the name of the material into the search bar and clicking the Materials tab.

Trimble has launched a new import tool for SketchUp 2023 that enables Revit models to be converted into SketchUp geometry ‘faster and more accurately’, and resulting in ‘much lighter models.’

The new Revit Importer for Studio preserves model structures between Revit and SketchUp. According to Trimble, Revit families and layers neatly translate to groups, components, and tags in SketchUp, meaning users can save hours or even days of model cleanup.

Revit levels are translated to SketchUp section planes, while Revit material colours and transparencies are respected during import.

Other new features for SketchUp 2023 include improved flip transformations that lets users pre-visualise the outcome of flips to ‘model more predictably’; and an improved LayOut tool which now includes the ability to manage imported DWG files as references.

The Revit Importer is available natively inside SketchUp’s desktop application. Customers with Studio subscriptions can access the feature once they update to the 2023 version.

Customers with Pro subscriptions can install the Importer in SketchUp 2023 and then initiate a trial to evaluate the new workflow. No Revit license is required.

SketchUp Studio subscription also includes V-Ray 6 for visualisation and Scan Essentials for importing point cloud data.
