I'm trying to design a bottom and top form for a 90 degree formed part with a gusset in it. I was able to extrude the bottom block with the gusset feature in it by using "offset surface" the offset is 0, creating a plane away from part, "converted entities" to get the desired shape. Then extruded upto surface. That worked great on the bottom form but then when I repeat the exact same steps to the top form I get an error "the end face cannot terminate the extruded feature". Does someone know why it is giving me this error?
