If the view is set to 5—a right side view—and you create a point using view coordinates X1 Y0 Z0, the resulting point will have the absolute (world coordinate) values of X0 Y1 Z0. This is caused because the right side view is rotated such that the view X axis coincides with the world Y axis.
The origin of the eight predefined views is set at the world X0, Y0, Z0 location. User defined views can be created with the origin at any location. This can be used to create a Local Coordinate System. This view origin is used when using any CView.
When in CView 1, the view coordinates are exactly the same as the world coordinates.
When using view coordinates, be sure that the view coordinate system in use is the one specified by the CView parameter. Reset the CView to zero for the view coordinates to match your current view.
When the Depth parameter is set to a non-zero number, it changes the Z depth of the CView plane used for sketching. For example, using CView 5 again, a point sketched in view coordinates with the Depth set to 1 will now end up with a world X coordinate of 1. Changing the Depth shifted the resulting location by an X value of 1 inch because in the case of view 5, the view Z direction coincides with the world X direction.
