has anybody got a DXF reading function and a way to 
simply display the drawn polygons on the screen? 
I dont need them to move or anything.

Actually its pretty easy to read DXF files if you know the file format. Basically its 4 XYZ coords that make up a triangle. The 4th coord is the same as the third coord?. This goes on and on until the whole object is built. The best way to figure them out is to open one up and look at it and experiment. I learned a DXF file of a box. Be sure to have a copy of all the codes of a DXF file handy.
