is there a way, without redrawing all my model to modify this arc? I would simply like to push this corner a bit. (Like we would normally do in blender by moving some vertexes. If there is any tutorials I missed feel free to send it to me,

thank you,

If you can share the project, I could take a look and give you an answer.

You can modify your existing sketch. Or if you setup some constraints you could use it to modify your model.

Can you be more specific about the constraints?

To modify these sorts of things, i have always had to remove the radius on the edges first on the top and bottom then i can edit/change it.

Well, in that case, it’s hard to guess what exactly you did to get that form, so it’s difficult to suggest anything specific.

Too many geometries going on there to make it an easy fix.
