SketchUp gets extreme with skatepark designer Dug Ketterman

Dug Ketterman is a world renowned skatepark designer with an impressive resume of projects under his belt, including multiple X Games courses. Dug is an active member of the SketchUp community, and we spoke with him recently to learn more about his insane collection of skatepark and ramp designs. He also shared some modeling advice, so even if skateparks aren’t your thing, we still think you’ll take away some rad SketchUp tips.

How long have you been using SketchUp?
Before SketchUp, I had spent years and countless hours drafting skateparks and ramps by hand. My dad uses SketchUp for woodworking and suggested I give it a try. This was back in 2006 and I’ve been using it ever since. The speed and no-nonsense way of modeling had me hooked. I’m attending the Art Institute of Portland for my bachelor’s in Industrial Design and have tried several big name 3D modeling softwares, but SketchUp seems to be the only one that works with my brain.


What is important in skatepark design?
There are many things that go into a good design, all of which cater to different types of skaters. Some enjoy transitions like pools and halfpipes, while others skate on flat-ground and never touch transition. However, the one thing that all skaters can agree on is flow. You need to be able to generate enough speed to take you from one feature to the next with a minimal amount of pushing and without running into other obstacles. As I am creating parks, I am constantly thinking about distances, heights, gaps, angles and materials to determine proper spacing within a given boundary. I refer to this process as 'Flow Analysis': the study of spatial relationships between skatepark elements.

How does being a skateboarder and an architect influence your park design in comparison to an architect who doesn’t skateboard?
There is something commonly referred to as ‘the contractor's kink.’ This refers to the worst placement of seams and uneven skating surfaces that general contractors and architects unknowingly design into skateparks. There are many nuances to creating a well-skating park. This knowledge can only be gained through experience skating a wide variety of terrain. Rail heights, ledge angles, grind edge materials, seam and joint placement: these are just a few of the things that can make or break a perfect skate spot.

Contractor's Kink Example.jpg
A perfect example of ‘contractor’s kink.’ No space for speed, a large seam in the concrete, and a handrail that’s too high. Photo courtesy of thrashermagazine.com

Out of all of 'em, what has been your favorite project?
It has to be the 2011 X Games Street Course held in Los Angeles, CA. I had free reign not only to design the park, but also to be on site to finalize every exacting detail, right down to the grass coming out of the faux cracks and the authentic graffiti tags decorating the brick walls. It was exhilarating working as an art director with a crew of 20+ talented concrete, wood, and steel workers to help realize a 10,000 square-foot sculpture that was about to be skated by the world’s best athletes on live television in front of millions of viewers.

What are your go-to SketchUp extensions?
The Super Section plug-in has saved me tons of steps when creating construction documents. It's a genius extension for creating layers and scenes in LayOut. Also, Bitmap to Mesh and Sandbox Tools are great extensions for creating mesh surfaces.

How do you organize your models?
Groups and components are king. I treat every element in my model as if it were a separate material in the real world: plywood, 2x4's, scaffolding, etc. Grouping each piece separately allows you to quickly scale and resize as you draw and make modifications. Components are great for updating multiples of the same object in your model all at once. And nesting of groups and components allows you to create layers and scenes with quickness and ease. This, in combination with layers, helps hide parts of the design to keep things lightweight while modeling, and make it easy to view specific elements.

What advice would you give to new and aspiring SketchUp users?
Groups, Groups, Groups. This simple habit will save you from having sticky blob models that are filled with line fragments and impossible-to-edit geometry. I would also suggest starting with basic objects around the house and drawing them with as much detail as possible. This will bring about new challenges and force you outside of your comfort zone.

Smart modeling for building performance using SketchUp and Sefaira

A few members of the SketchUp team recently traveled to New York to spend a little time with the folks at Sefaira. Sefaira provides energy and daylighting analysis to help architects and designers drive decisions like form, orientation, and facade design with the aid of real-time feedback in SketchUp.

Together, we worked on a webinar called Smart Modeling for Building Performance. The focus of the webinar was to take a closer look at some of the decisions that drive building performance, as well as some SketchUp techniques that aid in this kind of modeling at early stages of design.


Check out the recorded version of the webinar from Feb. 19, 2015. The techniques shown in this video are aimed toward the use of SketchUp with the Sefaira extension.


We also put together a list of resources and answers to questions that were presented during the webinar. You can access those here and find more information about Sefaira on their website or on the Extension Warehouse.

Ready, set... Maker Bench

Screen Shot 2015-02-23 at 12.39.41 PM.png
Maker Bench is going to be an open source, CNC workbench for everyone. Sounds fun, right? Well, then, help us design a Maker Bench!

At SketchUp HQ, we spend a lot of time thinking about how SketchUp works, and trying to make it work much or even just a bit better. Over the years, we’ve found that SketchUp users think a lot about how SketchUp works too.

This got us thinking: It’s fun to think about how something works, especially when that something is used to make other somethings. We call this circular design task meta-making -- making the things that people use for making.

So, we thought it would be great to spin up a new meta-making project with the SketchUp and maker communities: it’s called Maker Bench, and it’s a CNC workbench for everyone.

(What’s that? You’re ready to start designing your own maker bench now? Jump into the SketchUp Forums to get going. Otherwise, read on!).

Along with Eric Schimelpfenig at SketchThis.net, we’ve been kicking the idea of a Maker Bench around for a few years now. In that time, we’ve built WikiHouses, Open Desks, geodomes, modirondack chairs, skpr bots, and lots of other things too. As part-time makers, we always seem to find ourselves retrofitting work spaces, jigs, and tools in new environments. What if it were really, really easy to design and build our own workspace, and then bring it with us?

Last year, we came across Ron Paulk’s phenomenal workbench. We were impressed (not to mention full of desire), and we wondered what Ron’s project would look like if designed for makers, not professional carpenters.

06a6376a8d93cf3f.jpg
Maker Bench: standing or sitting? You decide!

Our curiosity with this idea came to a point this past December, and we started asking ourselves, “what do makers need in a work bench?” Well, here are a few starting ideas:

Accessibility: A Maker Bench should be accessible to anyone who makes anything. That means it should be simple to construct and be fabricatable using tools that are commonly accessible at a makerspace or TechShop. Further, Maker Benches should require an economical amount of material and minimal hardware.

Portability: A Maker Bench should fit easily in your car.

Storability: Maker Benches should work well in environments where there may not be a lot of space (a garage, a worksite, a shop, or a makerspace). Ideally, it should be easy to break down and store one or many Benches.

Modularity: People have different workspace requirements or constraints. Maker Benches should be modular so that you have control over how much space you need.

Retrofittability’: Along with modularity for dimensional workspace, a Maker Bench should be modular enough to accommodate specialized use cases. A few that came to mind right away were drawing, CNC work, soldering, and 3D printing.

d9c25f99b50869c1.jpg
The top of each Maker Bench is removable and customizable. We’ve designed this one for use with ShopBot’s Handibot.

As we mentioned before, we’re only part-time makers, so another requirement for the project is that the designs for Maker Bench should be open for anyone to customize.

With that in mind, our first major step in actually making a Maker Bench is to ask you for help. What should a Maker Bench look like? What else should it be able to do (or help people do)? How can we make it better?

Jump into the SketchUp forums, and join our Maker Bench conversation. Tell us what you want to see in a Maker Bench. Better yet, download the starter-models and start tinkering. We hope to spend the next two months modifying the design, and then fabricate our first set of prototypes at Maker Faire Bay Area in May.

Along the way, we’ll share our conceptual and as-built models, our good ideas, our bad ideas, our cutting files, and our build photos. Please, join us! We’re aiming to meta-make a workspace that’s practical and useful for people who tinker and build, and we’re planning to have some fun while we’re at it.

SketchUp Multi-Tool Personalities: Part One

Did you know that many SketchUp tools have alter egos? You might think you know your SketchUp tools pretty well, but many have supplemental functions revealed in the status bar at the bottom of the SketchUp window that most folks don’t notice.

flat_pack-02-01.jpg
What’s that? The Eraser tool leads a secret life as a quick way to hide or soften/smooth geometry!
Keep an eye on the status bar for other modifications on standard tools.

The information in this status bar changes when different tools are selected. For example, when the Eraser tool is selected, you’ll see two key modifier hints in the status bar: hold Shift to hide edges instead of erasing them, or hold Option (Ctrl on PC) to Soften/Smooth edges. All of sudden, one tool gives you access to three.

However, there are a handful of tool abilities that are not communicated via the SketchUp interface. If you didn’t know about these extra options – it’s kind of like finding a $20 bill at the bottom of your drier. Take a look at the Arc tool, for instance. There’s a useful hidden feature here that was introduced in SketchUp 2015: you can automatically trim corners with the Arc tool by double-clicking immediately after drawing an arc. Here’s how:

  1. Select the Arc tool and click on one edge of a corner to start drawing an arc.

  2. Hover your cursor over to the adjacent edge; notice the “Tangent to Edge” indicator that appears.

  3. As you continue to hover along the edge, look carefully for the arc to change color from cyan to magenta. The magenta color indicates that you’ve located the point that is equidistant from the corner relative to your initial point (arc is tangent at both edges).

  4. Double-click when you see the arc change to magenta and SketchUp will automatically trim that corner.

  5. If you’d like to continue trimming corners at that same radius – simply double-click near other corners. Need a visual? Check out the animation of this in action below.

Automatically trim corners by drawing a tangent arc at a corner and then double-clicking with the Arc tool. Check out this Knowledge Center article for additional information about these methods.



Now let’s explore the Position Camera tool. It may not be used often, but it’s worth taking out of your tool belt once in a while. If desired, you can review this tool in our SketchUp Training Series: Position Camera / Look Around video. When you’re ready, try this in your current SketchUp model:

  1. Select the Position Camera tool; notice status bar informing you to “Select the camera position.”

  2. Click once on a point in your model where you wish to set the camera position.

  3. SketchUp zooms into the viewpoint you chose. The status bar now states, “Drag in direction to turn camera.” Note that your cursor now changes to the icon for the Look Around tool. This allows you to adjust your view as if you’re turning your head; the camera position is stationary, but you can swivel to look around.

  4. In Step 2, we clicked and released the mouse button. If you click and drag, the status bar indicates: “Select a point that the camera is aimed at.” You can now release the mouse button over a location in your model where you wish to look. One use of this is to perform a line-of-sight analysis where you want the vantage point from a specific location and the view aimed at a specific point in your model.

Position Camera lets you pick a vantage point in SketchUp and create a view looking towards a specific location in your model. (Models shown found via 3D Warehouse: Star Trek TOS Crew, USS Enterprise NCC- 1701- G, & 40 Acres "Mayberry" Sets)



We’re sure you’ve noticed that SketchUp will snap to specific inferences as you draw with certain tools. The Arc tool snaps to a half circle proportion. The Rectangle tool snaps to square proportions as well as the Golden Section (Golden Ratio). A dotted line with a Golden Section tool tip will appear when you’re in a position to create a Golden Section. Try this for yourself by clicking once to start drawing a rectangle – hover slowly – and look for SketchUp to snap to those proportions.

Looking for Golden Section proportions? Utilize the Golden Section snap in SketchUp to quickly draw with these proportions.

If you’re curious about what else you may have never noticed about your favorite SketchUp tools, here’s a list of some key modifiers you can find among the tools in the Large Tool Set:

Select → Shift = extend selection
Eraser → Shift = Hide, Option (Ctrl) = Soften/Smooth
Push/Pull → Option (Ctrl) = create new starting face
Move/Copy → Option (Ctrl) = copy, Shift = lock inference,
Command (Alt) = auto-fold
Rotate → Option (Ctrl) = copy, Shift = align to face
Tape Measure → Option (Ctrl) = create guides
Protractor → Option (Ctrl) = create guides, Shift = align to face
Orbit → Shift = pan, Option (Ctrl) = suspend gravity
Zoom → Shift = change field of view
Walk → Option (Ctrl) = run (seriously!), Shift = move vertically or sideways,
Command (Alt) = disable collision detection
Section Plane → Shift = lock to plane

It’s easy to miss some tool options and key modifiers when you’re cruising along in SketchUp. Don’t forget to occasionally peek at that status bar while you’re modeling; it might just give you the hint you need to proceed.

Taking a ride with Connor Wood Bicycles

Yup, you read it correct: Chris Connor makes bicycles out of wood. We did a double-take too when we met Chris at the 2013 AIA National Convention in Denver. At first, we weren’t sure why a bicycle builder was exhibiting at an architecture trade show, but without a doubt Chris’s ridable wooden bikes share the functional beauty of a well-designed building.

After having logged many hours designing the base geometry of his custom bikes with paper and pencil, Chris turned to SketchUp to streamline his design process. We visited his workshop in Denver to learn more about how he creates these timber two-wheelers.

Introducing 3D Warehouse Detailed Collections

Remember Component Bonus Packs? 2D and 3D trees, furniture and accessories, wood joists and roof details: these components, authored by the SketchUp team, have been a consistent staple of 3D Warehouse for years. With the release of SketchUp 2015, we’ve greatly expanded and improved SketchUp’s standard component collections.

As of today, more than 2,800 individual detailed pieces of new SketchUp-authored content are available on 3D Warehouse. As you browse the new Detailed Collections, you’ll find that many standard components, like this theater light, have been improved with a much greater level of detail.

Find more Film and Stage models here.



Similar to their predecessors, the updated and improved components are generic in nature. These new, detailed components have been uploaded alongside the simplified counterparts; the titles of new components end with “Detailed.” For example, the search result for “HMI Light 4000Watts with Barndoors” will display both the simplified and detailed versions of the component. It’s important to note that these new detailed components are typically more “geometry heavy” (a.k.a. higher polygon count), which means you should consider how they’re used in your SketchUp model. You may consider using simplified components as proxies and replace those with the detailed versions when appropriate (just take note of component insertion points).

You can access this treasure trove of content by browsing 3D Warehouse Detailed Collections via SketchUp’s 3D Warehouse window (File > 3D Warehouse > Get Models) or via your web browser. You can find all components and collections created by the SketchUp team by visiting our 3D Warehouse profile.

In addition to visual improvements, these components are also jam-packed with all sorts of useful information, including IFC attributes. Try exporting to Tekla BIMsight or Trimble Connect – both accept IFC files. You’ll see that the IFC metadata transfers too!

The release of this content provides a great excuse to browse 3D Warehouse in search of new components to include in your projects. We’ve taken special care to include relevant tags in each component so users can search and find exactly what they need. There are collections for Seating, Electronics, Jibs and Cranes... and many more! We hope you’re able to take advantage of this new content and that it helps you more quickly and more accurately express your ideas.

Reimagining the Veterans Memorial Tunnels

Jon Altschuld is a landscape designer for THK Associates in Aurora, Colorado. THK developed the aesthetic design for the Veterans Memorial Tunnels, a major highway infrastructure project currently being constructed along Interstate 70 near Idaho Springs, CO. (If you’ve skied in Colorado, you’ve probably driven through this stretch of highway). We talked with Jon about how SketchUp was used in this project.

One of the final renderings of the proposed tunnel design – SketchUp model rendered with Vue.


Tell us a little more about this project.

These tunnels (formally known as the Twin Tunnels) were originally built in 1961. This project focused on improving mobility within the I-70 corridor by widening both tunnels to three lanes with wider shoulders. The project also focused on addressing safety and creating unique features to serve as gateways for the area.

The previous design of the tunnel portals created a feeling of driving into a headwall, which caused motorists to brake and slow down when approaching the tunnels. The new design resolves this problem by integrating a spiraling tunnel portal that welcomes motorists into the tunnel gradually. These spiraling tunnel portals are the result of evaluating multiple design options on a variety of criteria.


Did you work with any data that was imported into SketchUp? 

Yes, most of this 3D model was based on imported data. The existing terrain information was collected in the field with LiDAR, and the LiDAR data was converted into a TIN (Triangulated Irregular Network) mesh in Microstation. Microstation was used because that’s the main software the transportation engineers use. The Microstation mesh was then exported to AutoCAD .dwg files as both a mesh and as contour lines. We were able to import the mesh file directly into SketchUp, and the contour file was used to create proposed grading files in AutoCAD. The proposed grading files, as well as the plan view geometry (road layout, tunnel layout, retaining walls, etc.) were all created in AutoCAD and the .dwg files were imported into SketchUp. Once in SketchUp, the proposed contours became meshes via the From Contours Sandbox tool, and they were then combined with the existing grade meshes.


How did SketchUp help in the decision-making process? 

This project used a Context Sensitive Solutions (CSS) approach, which involves creating and evaluating a number of options based on a variety of criteria. SketchUp was used to arrive at the final options that were evaluated in the CSS process, and for evaluation during the actual CSS process. Leading up to CSS, over a dozen different design options were created and explored in meetings. For these meetings, SketchUp was more useful than final renderings because we were able to look at any view in real time, as well as make design changes to explore additional options. During the CSS evaluation, SketchUp was used to compare four options side-by-side.

One of the west portal options in SketchUp. The pinkish area is existing terrain, and the purplish area is proposed (the big wall of purple is a large cut where rock was blasted away to create enough space for the wider tunnels).


How did you communicate or collaborate with other colleagues and consultants? 

We used one main SketchUp model with multiple groups and layers. I’m a bit of a grouping (and components) fanatic; it keeps models organized and the file size down. I mainly use layers for separating visual options, which was perfect for this project. One little trick was to place 3D text with the name of the design option in a visible place in the model (as seen in the image above) and put it on the same layer as the geometry for that layer. Whenever Option B was being shown, “Option B” text was visible; this helped reduce confusion.

I think the SketchUp images do a pretty good job of showing how we used SketchUp as a design tool, but what isn’t shown is how interactive it was for meetings. Being able to analyze and compare over a dozen options from any view, modify those options on the fly, and create new options while in meetings was invaluable. To work efficiently on the fly, the model needs to be created with that objective in mind. For example, having the different options on appropriately named layers allows you to quickly compare the options at the request of meeting attendees. Having the model neatly grouped allows you to easily modify pieces without affecting the whole model (be sure to know which pieces are groups and which are components). These in-meeting modifications to the model often are not as clean as the overall model and may require some clean up back at the office. Typically, I will save the ‘meeting’ version of the model, but only use it as a reference to make the refined edits to the final model.


Were there any SketchUp extensions that helped with this project? 

I use extensions every time I open SketchUp. Some that I use on almost every project – including this one – are Weld, Tools On Surface, Joint Push/Pull Interactive, Selection Toys, Bezier Spline, and PathCopy

The most challenging piece of the model to create was the spiraling tunnel extensions. I went through a number of trials to get the geometry correct; some of these trials used extensions such as Extrude Tools, Artisan, Curviloft, and Follow Me & Rotate. ThomThom recently released an extension called Bezier Surface that would have been really helpful had it been available when I was working on this model! 

Also, the ivy that is seen in the final Vue renderings was created in SketchUp using the SketchUp Ivy extension – this wasn’t added to the design until I was already working in Vue; that’s why the ivy doesn’t show up in the SketchUp images.

Tell us about the transition from SketchUp model to the final Vue renderings.

The transition from SketchUp to Vue is fairly simple. I typically change the SketchUp materials to bright solid colors so that I can easily differentiate them in Vue (unless there’s a SketchUp image texture I want to use in Vue). After cleaning up any unnecessary pieces of the model (such as unused options), I export the model to an .obj file and import that into Vue. All of the vegetation (except the ivy) is added in Vue. The boulders and talus slopes were also created in Vue. Vue recognizes objects based on material, so it is fairly easy to create and assign materials one-by-one for the model. The process typically involves a lot of quick, low quality test renders to fine tune the materials, lighting, camera, and atmospheric settings. Once these are all finalized, the high quality final renderings can be created – which can take a while. Some of the renderings for this project took 16+ hours to render! All that remains after that is post-processing work in Photoshop.

Final rendering of the east portal.


How do you go from SketchUp model to tunnel construction? 

For this project, much of the “base pieces” were already engineered and into construction documents when the SketchUp modeling began. For example, the core tunnel structure/bore, the roadway alignment, and the utilities were all pretty much set. The configuration of the tunnel extension walls, retaining walls, and proposed grading were all items that became defined by decisions from the SketchUp model. For these items, the beginnings of the construction documents were already in place from creating the linework in AutoCAD. From there, we simply had to bring these drawings to 100% construction documents and the General Contractor installed them. The General Contractor was involved in many meetings leading up to construction where we used the SketchUp model to better explain details of the design.
