Is it possible to create a 3D drawing of a normal drawing ??
Yes. There's more than one approach. They can be mixed. Check your docs for thickness extrude region solid I think thickness is quick and easy while extruded solids are better. The extrude route requires extra preparation. Essentially a trade off between ease and quality (again, in my opinion). You will know your needs better than we will. Work with the tools and see what they do and how they are suited to your requirements.
