I am using PADS Designer (VX.2.6) with PADS Layout (VX.2.6) in the traditional workflow (using netlists, not integrated). I need to make a modification to an existing design that I did not do myself. This design has custom design rules set in PADS layout. When I use the PCB Interface tool to create a netlist and then import it into PADS layout, the constraints from the PADS Designer project overwrite the PADS layout rules. I don't want this to happen. Is there any way to either:
1) Create a netlist that will not contain the constraints from PADS designer (This was just a checkbox in PADS logic)
2) Create a netlist with constraints but import in into PADS layout without these constraints overwriting the design rules
3) Easily save the design rules prior to import, do the import and then re-load the previous design rules that have been overwritten.
I have been unable to find a way to do any of these.
Thanks for your help
