Been looking into some Autodesk Civil 3D functionally that may go unnoticed. Working with a client who received drawing files from a surveyor and needed to create a surface from provided data. The command to move block objects to elevation was used.
Here is a note directly from Civil 3D Help:
As shown below, the survey point data blocks have note for elevations, but have a physical Z value of 0
To leverage the provided data, the MOVEBLOCKSTOATTRIBELEV command was used to ultimately create a surface model. The command can be found from the Surface contextual tab > Surface Tools palette or from the Modify tab > Ground Data panel > Surface button > Surface contextual tab >
The command opens a dialog box where you can select the Block name and the embedded Attribute to use.
The command automatically selects and elevates blocks to the embedded elevation.
