How can I remove unnecessary lines, surfaceses from one solid object group? Can I split a previously created group?

Hi,

you can create a new Shapes group. Tap on the “+” add a new group, and put the bodies you don’t need to that Group 🙂

I am sorry it does not work ☹ Additionaly program in exporting files keep a lot unnessery junks… lines, shells… ☹ The ascii SAT format is more comfortable.

If you want those lines removed you can unite the different bodies (or is this one body?) with the the Union tool
