Finally laptop is working. First off I updated the freeCAD to latest version which is under development. Then created a small model using materials. Then tried to import IFC file and came to know that for this ifcOpenShell is required. Compiled the software but it was not compatible and didn’t worked. So, I tried again and this time cloned from the github. It took long time but still didn’t work. For sure I am doing something wrong. Did lot of searching after that I think I found the issue. May be I will complete my task today. Deadly need a success this time. Hooo!!
