9/10 projects I have the site as a separate file. Simply for the fact that is much easier to move a the building around on the site, or the site underneath the building as a link. The only time I'll model the site in the same file is if the building pretty much occupies 100% of the site and thus doesn't have to move anywhere.

So yes I would suggest that.

Regarding my last question: Is the simple solution to create a separate site file and link in the building? Then I can move the building in x, y & z directions on the site and publish the coordinates back to the building file?

NOOB here, extremely frustrated with Revit's logic. I have no cad from which to import. I do have a .jpg with spot elevations, from which I've created the beginning of a toposurface by placing points aligning to the imported image. I now know my finish floor elevation and want the toposurface to correspond to it. It looks like my only option is to change my finish floor elevation to its actual height, or the topo ends up 3400' above the building. You say "Are you crazy!! Never do this!" I must be crazy because the program is driving me crazy! I just need to get on with my design and have wasted almost two hours unsuccessfully reconciling floor and topo elevations coordinate systems!

Unfortunately, the Revit "Help" is worthless for this topic. Can you tell me what I should do so that I can continue to develop my toposurface without moving it up and down 3400' every time I need to make a refinement to it?

Of course. Let me first state that 9/10 times I am simply importing a 3D survey from AutoCAD to generate the Toposurface. When importing it does need to host to a level, generally ground floor. Then I simply move the AutoCAD file in elevation down by the shared coordinate RL that the Ground Level represents. As such if, drawing a topography through placing points, I'd just let it be up really high to begin with. Then when finishing the sketch using the move command to position it correctly with the building. For the placement of the points there is no way as yet to tell these to be based off the shared coordinate system.

HTH.

This method doesn't seem to work with Toposurfaces. The levels for Toposurfaces can only be set to "Absolute Elevation". Therefore if you use the Shared Coordinates for your floor levels and then draw a Toposurface with the levels close to the RL's of your floor level, the Toposurfae will be created a lot higher up than your floor level is drawn. Is there a way around this (i.e. get the Toposurface to use the Shard Coordinates as well)?
