A special case of the linear Dimension tool is the Elevation Dimensioning construction method. Elevation Dimensions allow you to place height markers in Section/Elevation/IE and 3D Document windows.
Note: On the Floor Plan or Worksheet/Detail windows, use Level Dimensions. See Level Dimensions.
Elevation Dimensioning is calculated based on the Dimension Origin, which you can set as needed in Elevation Dimension Settings.
A series of Elevation Dimensions behaves as an associative dimension chain.
