I am using the opencutlist extension with Sketchup Pro (first time Pro user). Created a simple book case . all plywood… used “sheet goods” … plywood… (4x8x.75). When I generate a “parts” list I receive “Thickness Undefined” on each panel. What am I doing wrong?


It would help us to help you if you share the .skp file so we can see how you’ve set things up.
