Best workflow for Site/Topography in Revit LT without Shared Coordinates? (CAD survey far from origin)
I'm working in Revit LT and trying to figure out the best workflow for handling georeferenced CAD surveys and site modeling.
In the full version of Revit, my go-to approach was to keep two separate files: one for the Building, with levels starting at 0.00 as the ground floor, and one for the Site. Then link the building into the site file and use Acquire Coordinates to sync everything up.
The problem is that Revit LT doesn't support Shared Coordinates, which completely breaks that workflow and turns coordination into a headache.
I just received a new topographic survey in CAD. It's fully georeferenced, meaning it lives extremely far from the origin, which as most of you know brings its own set of fun issues in Revit.
So what's the best way to deal with this in LT? Should I modeling at actual elevation, meaning setting Level 1 directly to its real-world height, say 445.00m, instead of starting from 0.00m. The second is relocating the survey in AutoCAD first, bringing a known reference point to 0,0,0 before linking it Origin-to-Origin into Revit LT to avoid the 20-mile precision glitch.
How do you guys handle georeferenced sites and building elevations in Revit LT without ending up with broken sections and spot elevations all over the place?
