Hi,

I have made a pcb in Solidworks and wants to export it into Circuitworks, so I can import the ascii file into PADS.

We use PADS templates with minimum 4 layers. Therefore I have added 4 layers in Solidworks and the are transferred just fine into Circuitworks.

The problem occurs when the file has more than 3 layers. Then I get an System.NullReferenceException: Object reference not set to an instance of an object.

If the file has just three layes it can be saved as an ASC-file, but 4 layers is a no-go.

Has anyone an idea how to overcome this?
