I’m trying to model a security camera and need to cut into the casing to add in the lens itself. How do I go about cleaning up the edges?
The first thing I’d do is sort out the blatantly bad areas. Also, use of sharp edges and controlling the auto-smooth angle can be a boon. You can also use shrinkwrap on a “background” object to have the surface conform more to a smooth curve, using a vertex group, you can limit the effect to the “round” part and not the “cut” part.
This shows how you can use the shrinkwrap to handle shading.
Another method used, is to retopologize the model after all boolen operations are done.
I decided to go with this. Thanks for the suggestion!
FYI, you can use a shrink wrap to ensure your retopology matched the initial shape. So make a copy of the shapre prior to the boolean, use that as a shrink wrap target so as you retopo, the new points hold the a nice form.
