Currently the Elevation Benchmark tool only permits the use of document units.
If the units are feet and inches, the elevation benchmark units will be in feet and inches. There is no option to choose meters, for instance.
Dimensions have the ability to use secondary units. The stake object tool will allow users to choose units other than the document units.
It is very important that this incredibly useful tool be changed to permit the use of document units and / or user specified units.
In most drawings I produce I am required to use metric and imperial units. Vectorworks is very good this EXCEPT for this tool.
I would like to see this tool able to display units other than document units.
