Mechanical design for everyone: SpaceClaim 3D Direct Modeling
Tuesday, March 20, 2012

SpaceClaim is a solid modeling application with a goal similar to SketchUp: make a 3D mechanical design tool so easy that anyone can use it. We helped the SpaceClaim team read and write SKP files years ago, but their latest release is a big step forward for engineers who are looking to use SketchUp in their workflow.
With SpaceClaim, engineers can convert conceptual designs in SketchUp’s native SKP format (which is optimized for fast performance) into precise solid models needed for mechanical design and manufacturing. As an example, SketchUp models usually convert to CAD programs as meshes, so holes end up being made of lots of little faces. SpaceClaim uses its feature recognition technology to convert these features into exact cylindrical surfaces.
Take the model below: SpaceClaim’s SketchUp import tools automatically convert facets to precise geometry when possible. On the left is the original SketchUp geometry. The middle model demonstrates the new import capability, with no manual cleanup. And the model on the right is further improved using SpaceClaim’s manual repair capabilities.
Moving from concept to production model with SpaceClaim for SketchUp
With this functionality, mechanical designers can directly re-use SKP files, rather than remodeling from scratch. This type of precision is important for rapid prototyping, laser cutting, CNC machining, detailed dimensioning, simulation, and photo-realistic rendering. And SpaceClaim’s process produces models that are completely compatible with other mechanical CAD systems. Another bonus: these import tools enable mechanical engineers to use the entire 3D Warehouse as a starting point for their designs.

SketchUp Pro Case Study: Alexander James International

We recently came across some marvelous work from Alexander James International (AJI), an interior design firm in the UK that specializes in the Hotel & Leisure market. Michael Reekie, Senior Interior Designer for AJI, was good enough to provide some insight into how they use SketchUp Pro.
I started using SketchUp Pro about five years ago. At that time we considered it a tool to help produce quick 3D line drawings of small areas. Gradually, its value has become more apparent and with the recent addition of Shaderlight, it is now considered to be an invaluable tool by the whole design team.
At the earliest stages of the design concept, I import a CAD plan of the project into SketchUp from which I build a model. It gives us a three dimensional awareness and makes space planning both easier and more accurate.
The SketchUp model offers better awareness of space which aids in the design and in space planning.
I continue to use SketchUp Pro throughout the design process, periodically using a fast, low resolution Shaderlight render to check the progress of lighting levels, features, furniture, and finishes.
SketchUp model with entourage and Shaderlight lighting elements, when rendered, will help validate the design, look and feel.
When I am sure that no other changes are necessary I produce a high resolution rendering which is imported into Photoshop. I can then make any small changes to colours or light levels and add people or anything else that I feel would enhance the final visual.
Final Render: SketchUp Pro + Shaderlight + Photoshop
Before using SketchUp I produced hand-rendered visuals. The uncomplicated nature of the program has made the transition easy and very effective. SketchUp has become an invaluable tool for the whole design team.
A big thanks to Michael Reekie (michael@aji.co.uk) and the whole AJI team for providing this snapshot into their SketchUp workflow. Great work!
Modeling cultural heritage sites with SketchUp Pro
Thursday, March 8, 2012

CyArk is a non-profit organization dedicated to digitally preserving cultural heritage sites. They do this by collecting, archiving, and providing open access to data created by laser scanning, digital modeling, and other state-of-the-art technologies. CyArk is also one of the many recipients of SketchUp Pro licenses as part of our SketchUp for Nonprofits program. This case study came to us from Justin Barton, a Technical Services Manager at CyArk.
A perspective view of 3D laser scan data (terrestrial LiDAR imagery) of Mission San Francisco de la Espada, San Antonio, Texas.
As part of the ongoing effort to educate the general public and disseminate information in an interactive environment, CyArk uses millimetrically precise data from heritage sites captured with 3D laser scanners to model the sites in SketchUp Pro. In order to do this, we use two methods:
Method 1: Orthorectified imagery
Our 3D laser scan processing software allows us to export orthorectified images of the data. We begin by exporting a plan of the structure to build a basic block model from. The plan is brought into SketchUp Pro, scaled, geo-located (all of our scan data is geo-located with GPS), and then the model is created from the accurate plan data.
Using orthorectified imagery created from laser scan data to trace out the model in SketchUp Pro.
After we create the block model, we import orthorectified elevation views of the structure. We then trace the outline of the building and “push out” the unwanted parts to create the unique architectural shape. The elevation view is also used to overlay the photo-real texture information.
Method 2: Direct modeling from 3D scan data
We are also able to use the Pointools plugin for SketchUp that allows us to load the 3D laser scan data point cloud directly into SketchUp. This allows even more precise modeling directly over the data. Again, orthorectified images of facades are used to overlay texture information.

After modeling is complete, visitors to the CyArk website and projects interact with them in two ways: CyArk has an online, Java-based web app that allows users to view 3D point clouds directly, or view solid models such as those created in SketchUp Pro or other 3D meshing software.

The other way that users can interact with 3D models on CyArk’s website is by using the Google Earth plugin, which we’ve integrated into a web page on the site. This provides a navigable 3D environment in which users can see geo-located SketchUp models while interacting and viewing geo-located multimedia items such as architectural CAD drawings, videos, 360-degree panoramic images, photographs, historic imagery and more.
A 3D model of Mission San Jose y San Miguel de Aguayo, San Antonio, Texas created in SketchUp and viewed in Google Earth on the CyArk website. Multimedia items (architectural drawings, videos, panos, historic images, etc.) are geolocated on the Google Earth interface and represented as a variety of type-specific icons that surround the model.
In addition to modeling directly from accurate 3D survey information (as seen here in the San Antonio Missions project and associated iOS mobile app), CyArk and our partners have taken advantage of SketchUp Pro’s easy modeling platform to create historic reconstructions of sites and site features that no longer exist. For example, for a project with Fort Laramie National Historic Site, eight historic reconstructions were created in SketchUp. Users visiting the Google Earth map of the project can choose to see the Fort as it appeared in seven different time phases, as well as a detailed reconstruction of the Post Hospital. All were created from extensive research, historic photographs/sketches, consultation with park experts, and metrically accurate laser scan data of structures, standing ruins, and remaining foundations as the base for the models.
SketchUp Pro provides CyArk the tools to quickly and accurately model historic sites to create interactive 3D environments for members of the public, educators, students and researchers to access online. This aids us in fulfilling a significant part of our mission to share, disseminate and educate.
Thanks for sharing this story, Justin. If you’re interested in getting involved with CyArk, you can find out more about volunteering, becoming a partner or donating to CyArk on the Get Involved web page.
Have you ever brought an image texture into SketchUp and notice that the resolution isn’t as crisp as it is in your image viewer?
Notice that the image in SketchUp (Right) is not as crisp as the original image (Left)
No, you’re not seeing things. By default, SketchUp downgrades higher resolution image textures to a maximum of 1024 x 1024 pixels because in the past graphics cards didn’t have the horsepower to render models with large textures on screen reliably.
If you want to turn off this feature, you can do so by going to Properties > OpenGL, and checking the “Use maximum texture size”. With this checked, SketchUp will no longer downgrade your image textures to 1024px. SketchUp will communicate with your video card and if everything is up to snuff, your image will display at a new maximum resolution of up to 4096 x 4096 pixels.
With the “Use maximum texture size” selected, the image in SketchUp (Right) displays at a much higher resolution
Important note! Your first inclination might be to activate the “Use maximum texture size” option and bring in the highest resolution textures possible.
But as anyone well-versed in the “science” of modeling with textures will tell you, the size of images DO matter. Large textures can bloat the size of your SketchUp model and tax your video card and system memory exponentially. If you are going to use the “maximum texture” option, you will need to be extra conscious about the size of your image textures and choose which ones need to be at a higher resolution.
SketchUp Pro Case Study: NHS Western Isles Hospital
Tuesday, February 28, 2012
4:27 PM
GreenspaceLive is a software and consultancy shop based on the Isle of Lewis in Scotland. The company was founded in 2008 as a spin-out from the Greenspace Research, a low-carbon building and renewable energy research program at Lews Castle College, University of the Highlands and Islands. This case study about gModeller, the company’s SketchUp energy analysis plugin based on gbXML, comes to us from Donald Macaskill, Technical Manager and Energy Engineer at GreenspaceLive.
Making hospitals more energy efficient
Hospitals have unique energy consumption demands. Not only do a hospitals require lighting and heating 24 hours a day, but they also require ventilation, sterilization, laundry, food preparation and important medical equipment to be powered as well. Therefore, any improvements made to the building could drastically reduce the bills, freeing up money to be spent elsewhere.
The NHS Western Isles Trust are very proactive in trying to reduce their energy costs and carbon footprint. To determine their baseline energy consumption and carbon emissions and then to simulate a number of fabric and technology improvements to their largest building, they turned to GreenspaceLive. A hospital model and energy analysis workflow was created in Google SketchUp Pro with GreenspaceLive’s gTools suite.
Completed model for gModeller
Project Methodology
To start, existing 2D CAD models and scanned paper drawings were shared via gWorkspace. These floor plans were then imported into Google SketchUp Pro. Once the floor plans had been imported, each floor was extruded to the correct height and dimensions. A detailed model is not required for the gModeller plugin, so the model could be simplified to single faces for walls, floors and roofs.
Once completed, attributes were added to the model using the gModeller's customised materials, located within the Paint Bucket tool in SketchUp. Next, spaces were identified using the manual Space tool, which allowed the model to have zone specific information, such as heating, lighting and ventilation for different areas.
The completed gbXmL model
The gbXML building information model generated by gModeller was now ready to be exported to an energy analysis engine. In this case, gEnergy was used, however, exported models can also be imported into Green Building Studio, Ecotect, Trace, DesignBuilder and others. gEnergy was initially run using the Hospital’s existing fabric and technologies to establish a baseline Energy Performance rating, subsequent analysis runs were then carried out with simulated improvements to the building, including proposed refurbishment changes, to determine the impact they would have on performance of the building.
Once gEnergy runs were completed, the model was exported to Google Earth and presented to the clients, showing gDashboard energy results on screen while touring their model.
The model in Google Earth with energy data
Using the gWorkspace cloud platform, the modeling team was able to share and collaborate with the client throughout the process. Team members and client representatives were able to view, download and share files from the project, as well as view all energy runs that were undertaken.
The Results
Armed with the tools and the data, NHS Western Isles Hospital were able to model different scenarios and view the impact these changes would have. The results were dramatic – making a number of changes to the heating system, the team was able to demonstrate that the most effective change would result in over 50% energy savings, while reducing the CO2 emissions by almost 80%.
Dave Tierney, part of the Energy Team at NHS Western Isles Hospital said, “Using gTools, senior executives and staff received an overview of our carbon emissions, energy consumption and the impact changes in technology and fabric will have on our building. We can clearly see the differences in low carbon technology investment options. The results will help shape our plans for tackling carbon emissions and energy consumption in the future."
To learn more about gModeller and the rest of the gTools suite, you can visit the GreenspaceLive website. You can also sign-up for a free trial. Thanks again to Donald and the rest of the gang at GreenspaceLive for sharing this case study with us.
Our March and April 2012 SketchUp Authorized Training Center schedule is now available. The map below contains information on specific locations, dates, and courses provided:
Allied Works is an interdisciplinary architecture and design practice that operates from offices in New York City and Portland, Oregon. Founded by Brad Cloepfil in 1994, the practice has been defined by a deep concern for the landscape, human experience, and craft, as well as the preservation and enhancement of the public realm.The firm drew widespread acclaim for its groundbreaking design for Wieden+Kennedy's world headquarters in Portland's Pearl District in 2000. The firm continues to draw in big-name clients, having most recently completed a new feature animation facility for one of the country's leading moviemakers and the much-anticipated Clyfford Still Museum in Denver, Colorado. We spoke at length with Brent Linden, the Director of Allied Works’ NYC office, about the firm’s work, its creative process, and its use of SketchUp Pro.

What kind of projects does Allied Works take on?
Allied Works can design anything, but in our history, we’ve mostly focused on museums, gallery spaces, creative work spaces, and creative educational spaces. We seek those out, but we’re also actively pursuing a lot of different programs as well.
My impression of Allied Works' design workflow has always gone something like this: Brad Cloepfil (the firm's Founding Principal) sits down with an enormous pad of paper and a lump of charcoal. He proceeds to make huge, gestural drawings that are equal parts light study, parti diagram and abstract rendering. A few years later, the building opens. What happens in between?
Let’s talk about the Clyfford Still Museum, given that it’s at the end of its cycle in terms of design and construction. It was a competition. Brad did have a stroke of insight, much like you were saying. Charcoal and pastel are his main generative tools. The project is really about the earth and about the light, so charcoal happened to be perfect. When he came into the office, he had a sketch which was about the intersection of those two things.
darkness, light, earth and sky; concept sketch, charcoal and pastel on paper
Then we have our design team, which sometimes includes people from outside of our office—collaborators like structural engineers and landscape architects. We spend time figuring out what all the parameters are, all the forces that are involved: cultural, civic, economic, experiential (which is huge) and structural. And then the form is derived from the mixture of all of these design elements. We do heavy investigations with material models; we do a lot of concept models to try to tease out the main essence.
Are those physical models or digital models?
In this case, they were physical models. We were trying to understand, through material manipulation and assembly, more about the experience and the form and the message of the project. "Message" is really the only word I can come up with. How is it “of the place"? How does the material itself communicate something about the experience?
spatial and structural orders; model study
Our design work strives towards a unity of space and form—the form itself trying to be a single body that’s understandable as a single body. With the Clyfford Still Museum, this was especially true. It’s kind of an unfolded plane that’s folding back on itself. It’s solid from the outside, but the space writhes and weaves together on the inside. It’s like a nine-square cube; some planes are subtracted, and some planes are moved around, with the goal of making a space that feels continuous.
The way we work on this kind of project is with physical models, which you can see in front of you and turn around, or to work in a digital 3D space that you can work on quickly. The Clyfford Still Museum was the first project where we explored the interior of the building through a digital 3D model study. We primarily used SketchUp Pro, probably because it's so FAST. And everyone participated—from the people who were actually modeling (I was one of those people), to Brad himself looking at the screen and saying Why don’t we just move this here? Let’s look at it from this other position. Let’s move this wall here, etc.

He learned how to navigate the 3D space, and by the end of the project, a lot of our design meetings were just moving through 3D models to make sure that the understanding of the space that we were going for was being supported by all the different orders that were happening in the building: the structural concrete wall order, the order of moveable art partitions, and others. We made sure that we could see through the building the way we wanted to, that everything was supporting the experience we were after.
Would you say that you typically design from the inside out, or is there an idea for an exterior form?
It’s a dialog between the two, but I think the idea for the structure, the idea for the landscape, and the idea for the experience all happen at the same time. In a lot of projects, that ends up feeling like it’s from the inside out. We’re less concerned about the facades than we are about the experience of moving through the building.

Can you talk a little more about SketchUp's role in Allied Works’ design process?
SketchUp is a tool that we use for design studies and for visualization purposes; also, for making models that end up becoming renderings, or even drawings. We export vector lines and make them into plans or elevations or sections. Sometimes we use it for making diagrams—actually, it’s pretty useful for making diagrams, especially in concept phases or competitions, where you need either a 3D axonometric, or a section cut perspective. I know we used SketchUp to make the model for the animation for the National Music Centre project, and for some extensive renderings that were done for marketing purposes.

You talk a lot about things like light and materials and the way spaces make people feel—I think I’ve even heard the word “phenomenology” used to refer to how your firm thinks about architecture. Is there anything about SketchUp in particular that makes it useful to you, given the way Allied Works operates?
We’d want any tool we use to help us realize our vision for what the space is going to be like, in terms of its experience. I’d say that materials are key, light is key and the order of the space is key. Of those three, the last one is where SketchUp helps us work. Iterative physical models just seem to take too long to build now that we have a tool that’s much faster.
Another way to think about spatial orders is to think about sculpting space. If you’re sitting inside a network of physical planes that end up making a space, and you can see from where you are to some kernel of space that’s three floors up—and you’re seeing it through an atrium, or a matrix of walls, or something—it can only be done by building a physical model or by using 3D software.
interior spatial study; pencil on paper and 3D section model, SketchUp
The reason we use SketchUp is because we can do so many iterations so quickly. Our design process is very iteration-heavy. On the CSM, we iterated through the configuration of the walls and floor planes and roof plane to make it feel, at the same time, like a complex spatial organism and a single body. Getting those two things to come together is quite difficult. We probably made a thousand models of basically the same thing.
Are you serious? A thousand?
Yeah, but not full-fledged models—study models. We also use the Scenes feature to orchestrate animations of moving through the space. Because it’s not actually about single points of perspective; it’s about the experience of actually moving through the space — people don’t just stand still. I’ll click from scene to scene and we’ll review how the space unfolds as you’re moving through it. It’s like having a small physical model and turning it around in your hands, but with SketchUp, you actually get to be inside the thing.
iterative structural and spatial order study; SketchUp
What other design tools do you use? How does SketchUp Pro interact with the rest of your toolkit, and how does that interaction support your design process?
Extensive hand drawing, hand sketching, just to get details out. A lot of photo collage, primarily in Photoshop. A lot of concept modeling, which is different from spatial modeling. Our concept models are not white foamcore models; they’re the kind of models that you can only make in a wood shop, or through metal casting, concrete casting, or glass casting. We had a guy make a model where he hammered spikes of glass into this huge chunk of wood. He actually figured out how to do it without breaking the glass, which was ridiculous. Those are the tools we use at the beginning of our process.

carving landscape and earth; concept model, wood
Then we use Vectorworks, our drafting software, and Illustrator, and Photoshop, and SketchUp Pro to do diagramming and planning work in our programming and planning phases. When we get into schematic design, it’s basically the same toolset, and even on into design development. We end up doing generative design all the way through the end of CDs.
In some cases, we build concept models even for details. We use SketchUp Pro and Maxwell to visualize how details will look in the space, and how lighting will work. We work extensively—especially on our museum projects—with lighting designers. We’ve worked a lot with Arup Lighting Design. In the past, we’ve built 1 inch = 1 foot physical models that Arup would use for lighting analysis. These days, we’re more likely to build 3D models in SketchUp Pro to give them. They give us back rainbow-colored model renderings that tells us where the light is going to be hot and where it’s not.
What’s your workflow from SketchUp to Vectorworks look like?
Depending on the project, we export vector graphics from SketchUp Pro and import them into VW to use as a baseline for the drawings. With the CSM, we had a model that was 100% accurate to the drawings. People on the team ended up using the model to design the details before they did the drawings.
So your SketchUp model reflects what was actually built?
Almost. I think that during the construction administration phase, they didn’t keep it up—as always, there were some slight modifications made during construction. We used the 100% CD model for coordination with the mechanical engineers. I don’t know if they used SketchUp themselves or converted the model into something else, but I know it was very helpful for them. Like in a lot of our projects, the mechanical space is really tight, so coordination was tough. Having a 3D model was key.
Is there a feature specific to the Pro version of SketchUp that you find particularly valuable?
Going through the list of Pro features, it’s obvious to me that we couldn’t make do with just the free version—primarily for the communication between different software packages. We’re always moving back and forth between SketchUp Pro and Vectorworks using DXFs or DWGs; going back and forth between SketchUp Pro and Rhino using 3DS, and sending MXS files to Maxwell Render Suite.
We also love the Solid modeling in SketchUp Pro 8. We’re doing a lot of furniture work now, and we use SketchUp Pro to do that modeling. For the current version of the furniture we’re working on, it has a lot to do with the idea of carving out of a solid body. So we model the solid body, we model the shape of the “carve”, and we subtract one from the other. Before the Solid tools in SketchUp Pro 8, we would have had to make both of those forms, intersect the two to generate the necessary edges, and delete the extraneous faces. Now I don’t have to do all that. Solid tools are definitely a big thumbs-up for me.
Clyfford Still Museum furniture studies; SketchUp, Maxwell Render
If we told you tomorrow that you couldn’t use SketchUp, what would happen to your design process? How would you work?
I guess someone would just have to get a lot faster on some other kind of software. None of the other programs we use are as fast; we’d be taking a step backward in terms of the speed at which we can produce design iterations and models for visualizations. It would be tough. Please don’t do that.
Pro Case Study: Safety Training with Turner Construction, Part 3
Thursday, February 16, 2012
11:42 AM
In our third and final installment in our blog series profiling Turner Construction, Jim Barrett, Director of Integrated Building Solutions explains how Turner uses SketchUp Pro as an innovative training tool:
Turner takes advantage of SketchUp Pro’s ease-of-use, friendly environment and the 3D Warehouse as a fundamental tool for introducing Turner engineers, superintendents, and safety managers to Virtual Design and Construction (VDC).
Safety Example Model: Excavation Logistics
Turner training courses begin with teaching SketchUp Pro. Many VDC concepts are taught through SketchUp. SketchUp Pro is also a core tool and foundational step towards Turner’s advanced VDC tools and processes.
Turner Safety Manager Training in SketchUp
Jim explains, "We find that SketchUp Pro is a great tool for introducing fundamental modeling and analysis skills to all construction families. At Turner, we include SketchUp Pro as part of the standard program installation package on all computers. This makes SketchUp just a click away for all users."
Safety Example Model: Edge Protection and Opening Coverings
We'd like to thank Jim and all the folks at Turner for giving us a detailed peek into how they use SketchUp Pro in their operations. We look forward to hearing more.
