Ok so I downloaded some free 3d arial scans of my hometown in dwg-format from the web. I isolated my school and now wanted to make it a 3d-printable stl-file.
Problem is that the files I downloaded are generated hollow. How do I easily make them solid? I can export them fine as stl, but they are hollow.
Also the buildings are at various heights and angled at the bottom because the ground is not the same height. How do I easily generate a terrain between the buildings groundlevel so they are not floating and can be printed as one piece?
Any help and input will be greatly appriciated. I have tried youtube, google and looking through extensions but to no real help.
I have uploaded the file here.
