I drew a number of rectangles in BobCad using 4 separate lines to make each. When I brought the DXF into PW it treated each line as a separate item. I tried to 'select all' then 'join open vectors' but that didn't work. I went back into BobCad, and selected each line, and joined it to the next line, but that didn't work either.
How can I join them, either in PW or BobCad?
