I have one project where the Invert Elevation reported in the Properties palette does NOT reference any specific datum, see attached image.
The Ground Floors level is at the Survey Point datum. The Project Base is approximately 13 feet above the survey datum.
What is making the Invert Reference about 182 feet off ???
This is causing an issue with the tag I created that displays the invert elevation. When using the spot elevation, I am able to get the correct RELATIVE and PROJECT elevations for the pipe. The tag is reading this property info which is incorrect.
I could not find a setting to correct the error, I hope it is an easy fix.
