Hello everyone,
I am new to zbrush. I have a question about scaling change.
I would like to enlarge the inner circle by 5mm in order to print the part. someone would tell me how to do that.
thank you so much
Zbrush is not a parametric modeler so you can’t simply enlarge the hole and have everything else adjust itself to the new size.
If the topolgy is simply enough around the center and 5mm enlargement doesn’t exceed the distance of the shallow rim around the central hub then you could mask all vertices except for the inner central edge and then scale outwards with the Gizmo.
An alternative is to make a cylinder with the desired diameter of the hole., position it in the center and then Boolean subtract the cylinder which will leave a mesh with the desired large hole. I think this might be the easiest method if your goal is simply to print it.
Search Michael Pavlovich YT Intro to Zbrush for the basic details of Boolean, Gizmo etc.
