Problem with Project Base Points

[Anonymous]

I'm trying to set up models in navis 2014 for project co-ordination with information coming in from Revit and ArchiCAD.

1st problem I have is that I have a Revit model, in this case 4 walls, then I move the Project Base Point to mke the bottom left corner 0,0,0 when I export a Revit model using Project Internal settings to NWC and open up in Navis, it's using the Relative Co-Ordinates, so it now shows -8.41,-7.41 (The distance away from the original Project Base Point)

Is there a way I can make the export use Project Base Point so in Navis the bottom corner shows 0,0 without having to add in data to the 'Units & Transform' box.

Thanks,

Matt.

It looks like when you export specifying Project Internal, the project is exported using Revit's (internal) project startup location.

Note: The project startup location cannot be changed.

To get the project to export with the coordinates that you want, you could move the project geometry to the project startup location (so that the relative spot coordinate shows 0,0) or you could move the Survey Point to the Project Base Point, and then export using Shared coordinates.
