OK, that was because I had OrCAD running. I've got past that point now.
I got this error:
I clicked OK, then cancel and it seemed to draw the part.
Is this anything to worry about?
This is caused by using an older version of Allegro/Orcad than the tools default version. It normally will not matter for average parts since it is just loading a default design to start entering data into. However, for parts that are very complex, the layer structures in Allegro's default file may not contain everything we need. The current version we are using is set up for version 16.6 You can look into the c:\ultralibrarian\cadinfos\allegro directory and you will find the following files:
These are set currently as version 16.6 If you are running a version prior to 16.6 you need to select one of the saved files which is appropriate for your version and renaming the above files name the version you select to be your default. Something like the following would work at the DOS prompt:
copy blank_drawing.dra blank_drawing_16_6.dra
copy blank_drawing_16_3.dra blank_drawing.dra
copy blank_board.brd blank_board_16_6.brd
copy blank_board_16_3.brd blank_board.brd
This will replace the setup files used for version 16.6 to use setup files for version 16.3
You can create any missing versions by opening an older version in Allegro and saving it to the appropriate version.
