I’m trying to place elements in a model based on known coordinates but all the coordinates are relative to the survey point not the project base point. I have the graph working exactly how I want it, other than it places the elements relative to the project base point. Is there any way to change this? I have put the project base point at the survey point, all the families are in the right place but as soon as I move the project base point, everything moves with it.

Hello, did you see this thread already? [image] Getting coordinates from Project Base Point or from Survey Point? Revit Hi all, I’ve been working on a script to have Dynamo read an excel file with as-buit piles and have them show up in green and red in Revit when they are within or over a set distance from the designed pile. I thought it worked. Well…it did in my test project with 6 piles and about a meter (X and Y) away from the Project Base Point and the Survey Point. These two, in my test project, are in the same place. But the true test comes when one is using the script on a real life project. So before …

I didn’t but have worked something similar, it then places in the correct position relative to the survey base point using the transform functions. It might be easier if I explain what I’m doing. I want to create a map of all the known control points of a campus, then each project will have a different project base point but the same survey point. Then the control points can be used to check the correct positioning. So I want to make them to always be relative to the survey point (even when not running the script) rather than the project base point. If it can’t I can just create a separate control points file and link it, wouldn’t be the end of the world!

This could maybe help (but I didn’t test it yet in real conditions): [image] The placed family instance could of course be a dummy cube instead…
