Anybody know how Joseph Drust created the circular inset depicted here in one of his zclassroom videos? ZModeler or something else?
At low enough poly level, many insets will become circular holes when subdivided as long as the edges are creased/reinforced, but the corners aren’t. See this vid:

It was probably just something like that that was then further subdivided.
There are no instant Booleans as such with ZModeler at present. You can join meshes, but it takes a bit of work. You can, however, dynamesh-boolean two objects together, then make use of the new “keep groups” functionality in ZRemesher 2.0 to ZRemesh them into manageable low poly geometry. ZRemesher 2.0 does a better job with hardsurface objects than the older version did.
