As I covered in last week’s post, Trimble recently released a new point cloud extension for SketchUp, Trimble Scan Essentials For SketchUp. In today’s post and video, I am using this tool to perform some analysis with the same 3D point cloud data that I introduced earlier (a scan of our classroom). I am basically checking how level the floor in our classroom really is by using what is aptly called a “floor flatness analysis”.

This approach is useful to verify any concrete work, especially if tolerances were defined in the specs. As you may have guessed already – our classroom’s floor is not overly flat at all in some areas.

My solution uses the extension’s Inspection Map feature and simply compares the floor scan’s points to a planar reference surface. This then results in a color-coded map that nicely illustrates where the ridges and valleys are. You can even label individual points and produce well-documented reports from this. Of course, the same approach also works on surfaces that are not horizontal. Just adjust the method as you need it.
