I've been working with the 3D Studio R4 and dxf2rsd.exe and rsdv.bat programs to create 3D models on the PC and display them on the Yaroze. What I've seen is that anytime I create a boolean object where at least one of the base objects is a cylinder, the resulting image is completely messed up. (Okay, you can kind of see the intended shape). There are extra triangles going off into space, missing triangles, triangles with the normals reversed, and hay, even a few "normal expected" triangles :-) For example: Try to create a 3D "P" shaped object from a cylinder and a box. Make a union boolean object, save to .dxf, convert dxf2rsd -back file.dxf, and read using rsdv.bat. Wierd, huh? I have not seen this problem when making boolean objects from just boxes for example. Only when I throw a cylinder (or "tube") into the mix. I'm assuming that the problem is with dxf2rsd.exe, but I'm not sure. Anyone have any other ideas? Ed Federmeyer
