Extrude along normals problem Im trying to extrude this edges along normals over Z axis. Median point selected and Z is pointing correctly as shown in this picture.



But as soon as I press E to extrude and Z Z to use normals restriction, normals Z axis changes to this:



So extrusion is not what expected.

What am I missing? Thanks in advance.
Answer by Paul Gonet in the comments. Thank you so much.

Select the edge loop around the hole and fill it with F. Set the transformation orientation type to Normal and then extrude. – Paul Gonet

That worked as expected. Thanks a lot, Paul Gonet.
