Finding point coordinates within a specific coordinate system

Revit
1

Given a bunch of points and a specific coordinate system, I want to extract pt.X pt.Y values, not from the world coordinate system but from that specific coordinate system. How do I do that?

Do you want to move the points, or get the XYZ values in the new coordinate system?

I just wanted to get XYZ values in the new coordinate system.

I have solved it in the following way:

For a point P:

  • construct a vector V from the coordinate system’s origin O to that point P
  • get the dot-product between vector V and the coordinate system’s X axis, thereby getting the ‘X component’ of vector V in the given coordinate system
  • do the same for the Y axis, getting the Y component

You can use “BriMohareb_2023” pakege it has node to get point coordinate based on cs. @jnoordzij

For everybody interested in a reproduction, here is something you can use / better understand the idea
