Hello, I have just started creating a model. The diameter of the circle in this image is 49mm. I want to make it 68mm. I want to widen the channel below it as in the image. How can I do this?
As I understand, this is an existing model that you imported and now want to modify.
First of all, the format of the model needs to be determined.
If it’s a mesh, the only way will be to cut out the part and remodel it yourself.
Otherwise, you can try using Offset Face or similar tools.
In a video they were cutting using sketch, how can I do it?
Draw a sketch, extrude and then subtract.
