Extrude resolving the wrong direction

greg.livermore — Fri, 07 Feb 2025 19:16:51 GMT

Hi,

Unable to find this issue elsewhere...

When I extrude a body and select "join" the preview is correct. When I press OK, it extrudes in the opposite direction.

When I delete the other body, the extrude still resolves in the wrong direction.

Attached is the file and a video of the problem.

Regards,

Greg

Are there any unresolved issues highlighted in your Timeline?

In your example, the Extrude directional arrow is pointing toward the side you want, down, but you are entering a Extrude Distance Value of -.5mm so it will extrude in the opposite direction. If the arrow points in the direction you want, the Distance value will be positive not negative.

Hi All,

Thanks for the replies.

There were unresolved issues, but sorting them out did not help.

The arrows point UP, on selecting the surface, so the negative value seemed correct. When I enter the -5mm value, the arrow direction changes direction as you can see on the video/screenshot. The extrude is correct up until the OK button is pressed and then it changes orientation.

However, I did keep looking and found THIN EXTRUDE, which was a way around the issue I have attached a video for any other newbs that get stuck!

Kind Regards,

Greg
