, I 'play' with CAD both professionally and at home, 2D cad at work usually means I delve into 3D solid CAD at home to do what I call visualisations of equipment that are being purchased by clients and how they look in there rooms / spaces etc.
As some of you have read recently, I have attempted to create Kerrsy's cormorant, though it looks reasonable good its got a few internal voids created when one solid does not merge with another as expected - due to haste some of the feathers were not made 0.5mm wider than most of the others so hence the voids when a merge is done, though they are only about 0.05mm wide there are a few, in Autocad 2014 which I am using, there does not appear to be a way of deleting them other than creating a shape that basically wipes out the void, these voids are only apparent in the wire view, and other than having another go at merging them so they are all inside each other, that's my only other option.
The main problem is not the voids but the file formats in export, I can save in 3 different AutoCAD formats and 3 different DXF formats (all year related), but I am perplexed with the exporting, stl (lithography) appears to just create a certificate, 3dxf appears to create a pdf view, and iges - well its any bodies guess.
Just as a way of giving Kerrsy a file he can pass on, is there any suggestions other than that of the file format - dwgs (by the way I supplied all 4 formats dwg, stl, 3dxf & iges to kerrsy).
