Newbie here. I am new to Blender, I am wondering is it possible(in sculpting mode), to model a square indent into the object.
Say I have a cylinder or a cube, and I want to extrude a small square region on one of its surface(you can imagine this to be a building). It has a square window, and the window is slightly out of the building's wall plane. I hope to repeat this effect for every surface, and each surface will have three by three windows. I don't need the window to have perfectly sharp corners. It could be slightly rounded. Thanks for the guidance.
