I have a DXF file with a lot of double sketch lines. Is there a way (command) to delete all double lines instead of selecting all the lines manually?
Clean the DXF up in Draftsight or AutoCAD first. There are commands for this.

Unfortunately, I only have the free Draftsight edition and no autocad.
This command is not available in the free Draftsight.
If you want to post the file I can try to clean it up for you.
Thanks Christopher, but I think I accidentally solved the problem.
I tried the Repair Sketch tool (Tools menu - Sketch Tools) and then I could extrude the sketch without problems.
