I have a simple 2d design that was constructed using several line segments. I have not been able to figure out how to weld the individual segments into one singe segment. When I extruded the item it left a hollow void. Only the lines extruded when it was suppose to extrude to a .125" plate. Any ideas what im doing wrong here?
You don't want to weld line segments together. The way to join them is first select and "combine" them and then use your shape tool to join the nodes.
(Edit) Sorry, I just read Mikes's comment more carefully and realized that I repeated what he already had said...
