Hello-
Solidworks is looking for their Top 10 List for Solidworks World 2010. I posted an idea for a sheet metal slot and tab feature to be available to locate the edge of one sheet metal part on the face of another. Others have proposed this idea in the past.
If you would like to vote for it, log on to your customer portal and look for the title "Sheet Metal Slot and Tab" in the sheet metal catagory, ID#1402.
Thanks,
Tyson
