Hello Blender World,
Ever modeled a building and wished for a button that will add a door? Or a button to add stairs or roof? We have got you covered.
Quick Arch is a blender add-on that provides such one button solutions to all architectural needs. Just select the wall face and click the button “Add Door”. Poof, you have a door with clean geometry and properly cut wall faces. And we have got a whole range of such operators :)
