“Error reading surf_head for VRT file” while generating profiles
After sampling existing ground, going to PROFILES / CREATE PROFILE / EXISTING PROFILE yields an error, “Error reading surf_head for VRT file”.
Workarounds: This bug seems to be drawing specific rather than project specific or user specific. There are several theories in Autodesks discussion groups. The only time that I encountered it, I was able to correct it by deleting that drawing files CGX and DFM files.
