I am grabbing all instances of Revit Links, then their coordinate system origins as a point and comparing to the Internal Point. The CoordinateSystem.Origin point is correct, though when I attempt to extract X,Y,Z to compare, I receive a very odd error. See screenshot below. Has anyone experienced this?

BTW the error is coming across in the [0] item. Tried to refresh the results and run again, with the same error being produced.

Peculiar. I am in SI and the other 7 instances available in that same list all exist in an SI world.

I’ve added a Math.Round after the Point.X node and receiving a 0 as a result.

I’ve also noticed that True North shows in Revit at a 90 degree angle, but reports in Dynamo at 89.99999 etc.

Maybe comparing “close” numbers here is in store.

I’m headed to the Moon! P.S. Thanks for the answer.

How do you get the coordinate system of revit links?
