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 can try setting the "Enable Node Tracking" Option ON. It will track the nodes even if you are using a pick tool. Not the exact result as you expect but a workaround.
Tools > Options > Workspace > Display --------- "Enable Node Tracking"
