I can't dimension a helical swept cut with anything circular in it.
Extrude circel to round bar
Sketch circle on edge (thread)
Cut-sweep with helix and sketch
Insert section view, display only surface etc.
I see the thread to dimension and get: "the selected entity could not be
converted into line or circular arc"
I tried to make a silhouette edge in the part; Select the cut-sweep feature,
split line, silhouette etc.
I use SW2003 SP3.1
