ACS Toolbox

The tools in the ACS toolbox are used to define and manipulate an auxiliary coordinate system (ACS) — a coordinate system you define that differs from the design plane (world) and view coordinate systems.

One ACS can be active at any time in a 2D or 3D design. While ACSs can be used in 2D, they are most useful in 3D design.

Note: All tools in a toolbox are not always visible by default. To see all tools, right-click in the toolbox and select Show All from the menu.
