how can i make 3/4 cylinder? Is there any command for that?
Make a circle and draw two lines at 90 degrees from the center to two quads, use Trim/Join to make a closed 3/4 circle figure, then extrude it solid…
thank you
revolve a straight curve 270 then OffsetSrf or ExtrudeSrf.
Make a full cylinder then Wirecut it with two joined 90 degree lines. Or BooleanDifference a box that has a corner on the base circle center out of the cylinder. Or…
There are always a bunch of ways to do this kind of stuff…
revolve a rectangular 270
