root/map_source/prefabs/(you can add folders in her if you like if not just keep it in prefabs)

These are all common prefabs for the correct height and widths of doors, windows, ect. The measurements were taken from the Treyarch Wiki ( https://web.archive.org/web/20090318115752/http://wiki.treyarch.com/wiki/Co-Op_Gameplay_Standards#Wall ). I DON'T WANT ANY CREDIT due to the fact its not my actual heights and widths, these are what treyarch says and such it was my duty to release the proper sizes to the public. What is included it:

• Double Door Frame
• Single Door Frame
• Single Stair
• 8 Stairs
• Single wall ( I set the height to the required height. The width was just random )
• Double Window Frame
• Single Window Frame
• Single Window Frame with wall ( This is to show how high off the ground it should be )

NOTE: For the clearances, i have the base below the orig's x axis. This is a small platform to indicate the ground level. ( This will come in handy with the jump clearance prefab, since it touches the platform. Be aware of that. )

Right click in the 2d view and hover over misc and click prefab then navagate to wher you put this prefab(or any other)
