I am importing a 5M DEM.TIF surface file from GIS. They have already converted it from Meter to Foot, and fixed the Geo Coordinates. The surface should be the low 5000' Elevation, but I am getting it in the 16000'. I am creating Terrain from surface selecting the tif.
I have recently discovered this defect using ORD and the NCDOT/Imperial workspace and US Survey Feet working units. The TIF file provided by the NC DEM is in US Survey Feet and projects into Civil3D 2020 correctly. ORD on the other hand keeps the Imperial elevation and projects to the Metric location. My workaround is to Transform the terrain using Metric to US Survey Feet, but manually setting the Z scale factor to 1.0; this keeps the elevations that are correct and projects it to the correct location. I too would like to now if anyone is working on this issue.
