Creating a point at a given coordinate relative to survey point coordinates

Hi @simon_murphy1, You have to be wary about how you do this. The Revit coordinate system can be quite complicated depending on how the project was set up. Let me explain… Revit has three points of interest and a rotation… Project Base Point Survey Point and the illusive Internal Origin Point Rotation How the project coordinates have been set up is very important to how Dynamo places geometry. For example, Unclipping while setting coordinates changes everything. Generally speaking, when yo…

This thread has some information. Basically Dynamo has its own coordinate system and you have to translate the information between the two.
