Illustrator files should be sent as ai. files. (Please note that EPS, PDF's, jpeg's and Bitmaps are acceptable also).
Google Sketchup files can be sent but leave shapes flattened, do not use the push/pull function.
For 3D files please send either OBJ or STL file types.
It's always a good idea to also send a PDF file so we can check against the CAD file, which can sometimes be corrupted when converting to our CAD/CAM software.
Intersecting curves and lines need to connect, unintentional broken vectors will require welding (joining)
Lines on top of each other can cause problems.
Polylines with thicknesses should be set to thickness zero.
