viaduct too far from the origin

[Sintecna_rws05]

hi everyone, I'm drawing a viaduct and I'm using dynamo together with excel to model it. The tracking axis of the viaduct expressed in meters uses georeferenced coordinates so the viaduct will be positioned very far from the origin causing inaccuracies. How can I solve it?

Hi @Sintecna_rws05 

You can define the project base point.

Late reply, you've probably moved on by now...

Since you're using Dynamo, provide a calculation to modify the resulting points by a common denominator to "move" the final form(s) closer to the origin. Alternatively, move the final forms closer to the origin after they are created.

Merely changing the Project Base Point does not place the elements closer to the Internal Origin which is what Revit is "concerned" about, keep the geometry of the model close to the origin to manage the required mathematical calculations in a way that ensures graphical representation is "easier" to produce.
