I would like to ask , how to create the elbow part of a metal type ( actually a J-shape Bolt Threaded material) .
I had finished the straight part by simply revolving my required profile. then i was to draw the elbow part but "sweep" doesnt work out
If all you want is a "j bolt" you need 2 sketches.. 1 is just a "J" shaped single line sketch.. Then the other sketch is just a circle starting on a plane perpendicular to the first sketch start or end point. Then sweep and voila a "J"
see attached (done with INV 2012)
A Google search on "J Bolts" shows the thread on the straight part only - so no, that isn't what the OP is after.
