In this video I use the example of a set of mitered beams to cover how to trim solid (i.e. volumetric 3D) objects in SketchUp. As always, there is more than one way to do this. In addition to what is mentioned in the video, also check out the Eneroth Solid Tools and Eneroth Slicer extensions.
This is a free sample instructional video from the book “Architectural Design with SketchUp: 3D Modeling, Extensions, BIM, Rendering, Making, and Scripting” (2nd Edition). I discuss this topic more in detail in that book’s Chapter 2.
Want more of these videos? If you own the book, use the password from the inside cover to gain access to all of my remaining videos on Wiley’s website: http://www.wiley.com/go/schreyer2e. If you don’t yet have your own copy, follow the links in the sidebar to get one. It is a great reference for SketchUp!
