I finally got the courage to load 16.6 SP3 and start a new design with it. Having to duplicate an existing layout with respect to many keypad switch placements, I thought importing some simple mechanical info from a client provided "dwg" might save me some time - - should have know better! Ranting aside - -
I converted the client's dwg to a dxf (2000-2002 format). Then with autocad viewer determined which of the 100 un-named layers of content contained the features that might actually be helpful for component placement. Using the Import>>DXF functionality, I selected and mapped the desired two layers of the dxf into board_geometry/assembly_notes and assembly_detail subclasses of a new blank board file.
Theimport onto assembly_notes subclass mostly imported OK except for line and arc line widths being weird. However, the import onto assembly_detail subclass was a disaster. Essentially 27 separate squares managed to import on top of one-another in a location not even close to their actual location (in the dxf) or relative to the location of the other features from the first layer import.
I used "incremental addition" and "use default text table" selections for the import process (thinking that one of the dxf layes did have some text on it). The dxf2a log only reports a few "illegal character substitutions" for each of the layers imported.
Any clues to what I'm doing wrong?
Thanks!
