Move AutoCAD block objects with attributes (such as labels or tags) at their insertion point to the elevation of one of the block’s attribute objects.
Use this command when you need to use block objects in the drawing as surface point data.
For example, the block object can display an elevation value from one of its attributes, but the elevation of the block reference can be different. Using this command prepares the surface data before defining a surface from block reference objects using the Add Points From Drawing Objects command.
