Coordinates doesn't alighned with Revit

Hi all,

I am trying to model sprinklers by dwg file.

I’ve extracted the sprinkler data to excel file (x/y coordinates) then push it through the dynamo graph, and fix the coordinates by substructing the coordinates from the project base point. Also I’ve rotated the points by the project base point angle, still the sprinklers are not at the right place.

What am I doing wrong here? Thanks

You have to transform your excel points to Revit coordinate system.
