I’m importing a dwg file created in sketchup into Shapr and there is a very small difference in size. For instance a part that is 3/16" x 3/16" in sketchup is 13/64" x 13/64" in Shapr. Any idea how to fix this?

Fastest way is to calculate the difference then select the drawing and use the Scale tool. In your case, 1.08333. (Double check my math first) This probably won’t be perfectly accurate due to the accuracy variables within shapr but should get you very very close without having to recreate the entire sketch.
