[#1]

is there a way to reconnect a frame member to a other sketch line? Lets say i've altered my sketch and delete a line to which a member was referenced. I get the error when rebuild the assembly.

When click change and select the said member i cannot select a new sketch line..

From my practical experience I don't think so. Deleting the line from the frame sketch basically says you also want to delete the frame member also. Just one of those things we need to keep aware of. Good luck.
