revolve will not work when axis is within part

jacques_chaurette

Hello, I'm new at this. I put a circle centered on the origin and a construction line down the center, When I revolve the circle around its axis I get a revolve error: "revolve did not generate properly - revolve would create self-intersecting part". If the axis is outside the circle it works fine. So my guess is that there is another way to create this 3D volume.

Thanks

@jacques_chaurette, it sounds like you are trying to make a sphere. Please see the following public document: https://cad.onshape.com/documents/e9b7c9ec7a6be8c12ed4f510/w/fdccace106c7e82ca6c61933/e/583d24a6330998876fe18ee4

What you want to do is split the circle in half with a solid line and only revolve half of the circle. There error you are getting tells you the exact reason why a full circle revolve is not working for you: "revolve would create self-intersecting part"

A half circle will revolve 360 to create a sphere, but as you found a circle won't revolve.   You can use the Trim tool to remove half the circle, then close it up by drawing a line between the two points, then revolve.  

If a full circle revolving 180 intersects itself, then it seems a half circle going around 360 would do the same.  So I'm not sure why one works and the other fails
