Re: CADSTAR Importer & Pad Stacks



Thanks for the advice. It will still be a while until I have something
working but yes, I will create a merge request once I have a skeleton for
the importer.

@Jeff Young - I've made you an editor of the document I made on Pad Stacks
Hopefully you will have received a separate email with an editor's link.
Let me know if that wasn't the case.
