About Elements Associated with Work Planes
A family that is work plane-based, or an element that is not level-based (a hosted element), is associated with a work plane.
Dissociate an Element from a Work Plane
When an element is no longer associated with a work plane, the element is free to move irrespective of a work plane.
Modify the Work Plane Grid
When using a work plane, you can change the spacing for the work plane grid, resize the grid, and rotate the grid.
Work Plane Dialog
Use the Work Plane dialog to show or change the work plane of a view, or to show, set, change, or dissociate the work plane of a work plane-based element.
