Exporting .brd file to DXF

 Doug,

In the Export DXF dialog  there is a "Layer conversion file" fillin along with an "Edit..." button underneath it. The layer conversion filename defaults to the dxf output file name followed by an"_l". If you select the "Edit..." button you will be presented with the "DXF Out Layer Conversion File" GUI. If you want to use the Allegro class names you can select the checkbox "Use layer names generated from class and subclass names or use the "New DXF Layer" button to add a DXF layer name to be used in the mapping. You then select the layer to be mapped to the DXF layer you want it to reside on. Once complete OK the form and then you should have no problems in exporting the file.

A hint I like to give folks is to only have the class/subclasses you want in the DXF output visible. The "DXF Out Layer Conversion File" GUI will only list those Allegro class/subclass combinations.

Hope this helps,

~Rik

Hi,

 I have been trying to do the same thing with no luck, and the same error "given layer filename does not exist".

I have followed the steps exactly. I am using Orcad PCB Editor 16.6.

All help appreciated. 

I got it eventually, good step by step here:

I had not my library path set up correctly, which was explained in the above tutorial, and not in any other tutorails or instructions I had come across.

The step I was leaving out:

The Lib button gives you the option to store a default cnv file. To set this up use Setup > User Preferences > paths > 

Library. Set the miscpath to the directory where the cnv files are stored.
