I can't make my object into a solid

I can’t make an object a solid and it’s keeping me from using Solid Tools to make a mold for 3d printing. SUPER exasperating. PLEASE HELP

Using the Solid Inspector, it shows me these, but I can’t seem to get to those edges to remove then, and Cleaner doesn’t remove them either

  • Scale it at 1000x
  • Enter the group (double click on it)
  • Select all Solid Groups and Explode them, then Intesect Faces
  • Exit the group and use Solid Inspector to delete all internal faces
  • It’s a Solid Group now
  • Use CleanUp for a clean model

would you mind uploading what you did? it would take me 4 hours to follow those steps as I use SketchUp about once a year

happy to send you an Amazon card or kombucha.org credit or what have you

If you make more changes, work at 1000x scale.

You’re welcome!
Thanks for the intention, but you asked for help and I gladly offered it.


I love the idea of making it 1000x scale to work on the tiny edges etc. Super helpful!
