To preface this question, I am a relatively new user of Chief (15). I am trying to delete a 3d solid (failed attempt at arched cabinet with doors). Why won't the 3d solid allow me to delete it?

these are the 3d solids I am trying to delete.

You will probably need to ZIP up the plan file and let one of have a look at it. Really no way to tell from this pic. Ensure you save the plan file and close out of Chief before ZIPPING the plan file, or it won't work.
