Need multiple different shared corrdinate points

[edgars_miskins]

Hi.
I need to export IFC in a specific coordinate system (I'm using survey point).
And I also need to export DWG files by using different set coordinates (that do not correspond to base, internal or survey points).

How can I achieve this?
Is it possible to define multiple survey points?
Or define null point manually for either export without it needing to be survey/internal?

It is 1 shared coordinate system (the world coordinate system)...When you create different Sites those would correspond to the User Defined Coordinate system(s) ... Once you link in the buildings to the Site Model, set them out (move rotate) then publish the coordinates to the links and save it to a site therein. Save to establish the Shared coordinate system. 1 WCS with several UCS(s)

Exports to DWG should be quite straight forward... Exports to IFC, you might run into some road bumps (depending on the exporter and the setting out of those sites, they might/do not line up consistently all the time)

Hi @edgars_miskins 

Start a new Project and link every building you need.

Move and rotate them to each location and on View/Manage and use Publich Coordinate Tool for every link.

That way, each building will assume their real postion on the site field.

Thanks for the reply.
I'm using the Revit's built-in DWG exporter. It has two options for coordinates: Interal Origin and Shared (which corresponds to Survey point).
I can't use Internal origin, since it's off. My only choice would be the Shared Coordinates.
But the thing is, I'm already using Shared for my IFC export.
If I set the Survey point so it's correct for DWG export it's not correct for IFC export anymore, and vice versa.

Thanks for the reply.
Unfortunately, my issue has nothing to do with links. Please read my question again.

After some more digging, I discovered, that it's possible to define multiple different Sites in Revit.
Under Manage tab -> Location it is possible to duplicate current default Site and change the Survey points as needed.
Just need to remember to switch to the corresponding Site before doing my exports.



Thank you for indulging me. This is now solved.
