Coordinate Systems in 3D Sketches

When creating a 3D sketch, by default, you sketch relative to the default coordinate system in the model. To switch to one of the other two default planes, click the required sketch tool, and press the Tab key. The origin of the current sketch plane is displayed.

If you orient the model along a standard view, when you press the Tab key, the model remains in the same plane.

To change the coordinate system for your 3D sketch, click the required sketch tool, hold down the Ctrl key, and click a plane, a planar face, or a user-defined coordinate system.

If you select a plane or a planar face, the 3D sketch planes rotate so that the XY sketch plane is aligned with the selected item.

If you select a coordinate system, the 3D sketch planes rotate so that the XY sketch plane is parallel to the XY plane of the coordinate system.
