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.
To move block objects to their attribute elevation
- Select a surface. On the Surface tab, click Surface Tools panel
Move Blocks To Attribute Elevation 
.At the Command prompt, enter MOVEBLOCKSTOATTRIBELEV. - In the Move Blocks to Attribute Elevation dialog box, select a block reference name from the list or click
to select a block reference from the drawing. - Under Select Elevation Attribute Tag, select the required tag.
- Click OK.
The selected block reference objects are moved to the elevation of the specified attribute.
