Hello, I am new to the forum :)I was trying to print a specific car (Audi 100), and I only found the type of model i will attach to the post. It is a .skp, i managed to turn it into .obj and import it into fusion360. I am stuck because I want to make the car solid, and the model is almost only faces, with no volume. Does anyone know how to turn it into a printable file?
