So I got this error message while doing a revolve and I don’t understand it. How do I prevent this or get my revolve to work?

Hi - the sketch looks fine. I tried to recreate a similar sketch and Revolve worked for me.

Please can you attach another image showing the full sketch or send the workspace to [support@shapr3d.com](mailto:support@shapr3d.com). We will quickly look into the issue and get back to you.

Thanks for sending the file as requested. I responded to your email. The issue was that the axis was slightly misplaced.

If it’s a straight line, you can also create the axis with changing the type from “2 points” to “edge”. Reduces the chance of misalign in this case.

Cool, didn’t know that. That’ll give me an “edge” the next time I make a construction axis. 😉 Thank you.
