Hi Michael,

Sounds like you've got it in hand in V4. In the mean time I might try and come up with some sort of pre-filter operation to remove lines that are smaller than some defined dimension. There are a lot smaller lines (hidden detail dashed lines and other spurious lines) that I could do without. Is this something that could easily be implemented with an MOI script? I might do some research.

BTW: I've really been enjoying using MOI lately, it's a breath of fresh air after using my normal 3D CAD programs - SolidWorks and Solid Edge. Thanks for a great product.
