I'm starting using this editor which is pretty cool and I have some questions.
When I add an object like a cube onto the editor workspace, is it empty?
If yes, what is the thickness of the "walls"?
2) Assuming that the objects are empty, and if I join 2 objects together like 2 cubes and they overlap, is it creating a new object with only the exterior (and it is empty) or is it keeping the "walls" that we can't see of the 2 initial objects?
Is there a difference if we group or not those 2 objects?
3) I notice that the smallest grid step is 0.1mm. Did someone print with such low steps on a home printer and were the details successfully printed?
