no cut-out when bezier curve within another?

Support Basics & Interface

using 2.28c

Following:

Specifically:
“When working with curves, Blender automatically detects holes in the surface and handles them accordingly. Actually a closed curve is considered as the boundary of a surface. If a closed curve is completely included within another one, the former is subtracted by the latter, effectively defining a hole. Return to wireframe mode with ZKEY and enter editmode again with TAB.”

This isn’t happening. To simplify it, I stuck a bezier circle within another (making sure they were fully lined up in all axes) - but still no cut-out.

Any ideas?

Add the inner circle while the outer one is in edit mode (yellow).

so simple! - thank you! And the hours I spent on it…

That doesn’t only apply to curves, it’s a blender opperations protocol. Anything added in edit mode is part of the same object and v/v.

If not created as one, many objects (or curves) can be joined with the Control J shortcut.
