I need to increase the thickness of the sidewalls in this model but keep getting blocked. I assume it’s all the rounded edges. I have tried to revert them back but it won’t let me change the radius back to 0.

At this point I’d have to remake the whole thing which is not ideal.

Hi,

Simply select the rounded edges, and delete them. Then you can do the change, and create the fillet again.

Interesting. I didn’t know you could just delete the chamfers. It took some doing but I got it. Sometimes adjusting one chamfer, changes them all and they become linked. It’s odd.
