I had this error if the path contained whitespace, because the external solver Calculix ccx 2.21 created the '.dat' file in wrong place.
@Serince I found no other solution than to catch the issue and inform the user that 'File path containing whitespace is not supported for Topology'

Thank you, Let me check the issue! Android için Outlook<https://aka.ms/AAb9ysg> edinin

I just did a test by creating a full path without any space: this workaround did the trick!
But for sure it will stop many windows users to utilize this function.

Btw, thanks a lot for this amazing mod/addon!! This is just remarkable!
A couple of questions:
1-I did a test for a personal project. I do have fix constraints which are on flat surfaces, not holes. Is it meant to work? Matter vanished away even on fixed surfaces (even at first iteration).
2-Is scipy really absolutely needed (I have installed it with anaconda)?
3-for the generative geometry, not sure how this works to add or remove object. I couldn't find any youtube demo nor instructions
