I am a Onshape newbie but have spent quite a bit of time on webinars etc. I still get stuck on really basic functions and so have gone back to really basic actions.
eg. Revolve. I draw a rectangle and then try to revolve it eg. thro 30 degrees. It comes up red and says" did not regenerate properly" I understand the problem generating a sphere from a circle - use a semicircle. I guess you could generate the segment by sketching it and using extrude, but I want to understand why I have the problem with revolve Thanks

rotation axis.
Here is an example of a sphere and a rotation of a sketch with the axis outside of the part:

Can you post a link for the document you are having trouble in? It may help to see what you are trying to do.
The origin cannot be used as an axis of rotation because it is not a line in space. There are many ways to rotate about the origin because it is just a point. (For example, a selection of the origin could be asking to rotate "over" the origin or "around the back"; there's no way to tell without a full line.)
I am still struggling. Take a look at Public doc Test3 I have created a line as the revolve axis. Just trying to revolve the rectangle thro 180 deg. Why does the revolve command come up as red and fail ? Is the selection sequence critical ? ie rotate - select face the axix ?
