I'm working on a part that relies on a sketch that I'm generating elsewhere as a DXF. The problem is that I need to iterate on this sketch, which is being used for a Boss feature in my Solidworks part. I need to reimport the sketch to make the boss work... however I'm making several more features that depend on the boss. How can I swap out the sketch that is being used for a Boss feature?
You might just be able to copy/paste the new sketch into the old one, and delete the old lines. If you want relations to remain intact to faces and edges on the boss then you can try the Replace Entity tool (if you are using 2014) before you delete the old sketch lines.
