The User Origin is created manually by the user to act as a temporary aid to drafting and measurements.
There are two ways to create a User Origin; either by holding down both the Alt + Shift keys (PC), Option + Shift keys (Mac) and move the cursor to the construction node where you want the origin located
or simply click the User Origin button, then click at any point in the window. The origin is instantly relocated there.
Note: If you want to return the User Origin to the Project Origin, double-click the User Origin button in the Standard Toolbar.
