Re: STL file
Hi Mathias,rnrnthanks for the reply.rnActually, I have a STL file and I used FreeCAD to open it. But I am not sure how can I set the boundary. I mean, how can I identify which one is wall, outlet, inlet, etc. I am really lost…rnrnThanks again for the attention!rnrnBest wishes,rnLiliana.
