Define user coordinate systems
You can apply a user coordinate system (UCS) with its own 0,0,0 origin and orientation in three-dimensional spaces. To simplify construction of three-dimensional entities, you can create as many user coordinate systems as you want, and then save and recall them as you need them.
Use a preset user coordinate system
You can select a preset UCS in GstarCAD. When you switch the view to top, left, front, bottom, right, or back, the UCS will align to the current view automatically.
