Hi there,

I need help and i hope this is the right forum!

I work for a company that makes 3D images in crystal blocks. Sub-surface engraving using point clouds. Our machine uses .cad files for this. The company that supplied the laser gave us software to convert the 3D images we take with our 3D camera into their .cad format. Now, the thing I need help with is this - how do I convert existing 3D files (eg. .3ds, .dxf)  into this .cad format so that they are compatible point cloud files?  The company, for some reason, won't give us the software they use or tell us what it is so I was hoping someone here who knows more about this stuff can help.

The laser machine that makes the 3D images in the blocks will also accept .asc, .pro, .pnt and .cbf files. I have downloaded a program called Biturn which converts to .asc but these files don't work. Huge parts of the models go missing when I open them on the laser machine.

I had heard that .cad files were created by/belong to a program called CadStd which I also downloaded but it can't read the .cad files that work perfectly fine on the laser.

Basically, I'm at my wits end and really need some help!!!!
