HOW TO INSTALL:
Press F4 in the viewport to and go to Preferences > Add-ons. Use the Install button found there on the zip file downloaded from the store. I repeat, the zip file itself not the contents inside. After that, just enable the add-on. You can search for it by typing its name in the search bar.
Pie menu hotkeys: Ctrl+Shift+X
Works for Blender version 3.3+
These Blender 3d add-ons are mainly designed for rapid environmental hard surface modeling for concept art and character modelling but can be used for many other situations as well such as creating movie or game assets and can also serve as an all around modelling support tool.
