Re: [PROTEL EDA USERS]: Protel / Specctra problems

Todd,

The board information is a little deceptive, I believe it includes anything
outside of the board area including text and mechanical layers,    Someone
feel free to correct me if I am wrong.

Second for blind vias to spectra,  open the DSN file in a text editor and
find your vias,  VIA0, VIA1, etc and manipulate the data in the DSN file
before importing to spectra.   Protel does not support the via information
well across the translation.  In the DSN file you can identify and change
the via parameters fairly easily.  You can change hole size, layers, etc in
the DSN file
