thick. The short flanges are about 20mm, and the slight arc is about
320mm wide. I created this part by shelling three faces. I'd like to
create a 2mm wide by 1mm deep continuous ridge along all the three
exterior surface (similar as if I would machine/mill or lathe a solid
part), but when I created a 2mm x 1mm rectangle sketch on one of the
end edge adn performed a cut command I can only select one target in
the extrude dialog box. So I'm ending up w/ a 2mm wide recess on only
one face. I'd like to continue this feature along the adjacent arc
surface and opposite mirror surface (inverted U-shape). I also tried
to KNIT (as well as few other suggestions) the three exterior surfaces
where I wanted to cut a 2mm recess, and still wasn't able to cut a
continuous 2mm wide recess along the flat-arc-flat exterior surfaces.
I'm a novice in this program and trying to teach myself, so please be
descriptive w/ your advice. However, I have a few years experience w/
AutoCAD and Vellum. Any excellent references will also be useful.
