Mr Anupam

Dear Expert,   I am facing issue in converting Indoor database --> vector database --> data format is .dwg

there are several layers when a 3D Building drawing is opened , it does not covert to 3D Building data and in Propman it says , prediction can not be made

Can someone, share a complete wallman tutorial using a sample .dwg file to understand where I am making a mistake

Thanks in anticipation

Sincerely
