Please install the Essential ACF Builder Collection

These addons aren’t required, but we strongly recommend using them to make your building experience better.

All tutorials assume the player knows how to use a physics gun and basic tools. If you are not familliar with those, please see the “Getting Started” and “Sandbox Tools” sections on the Gmod wiki.

ACF-3 is incompatible with other ACF forks, such as:

• ACE

• ACF2

• Unofficial ACF-3 uploads
