Hi all,
I have been wrestling with this problem for quite some time now and would really appreciate any help. I checked out some of the Coordinate System Transformation posts on the forum but it does not seem to work for me.
In the picture below, I want to place a certain family at the point, but I am not able to get the desired point coordinates in Dynamo when I use the Spot Coordinates locations (w.r.t. Survey Point) as inputs.

You need to rotate the coordinate system in the other direction, so “Angle to true north” \* -1

Thanks. Still, there’s a huge difference and the point family gets placed at a remote location in Revit.
I also tried (360 - Angle to True North).

Can you show how you get the coordinates by Element.GetLocation?
What is that Element? How is it created? Does it come from a linked file?

Yeah, I manually placed a spherical marker point family in Revit as visible in the original post (E 227743, N 407763) and got its location in Dynamo through Element.Location+ node.

ok, you dont need to rotate the coordinate system at all…just connect the nodes like this:

Despite _Angle to True North_ being a _Survey Point_ parameter seems like the _Base Point Coordinate System_ is rotated with respect to the _Project Origin_

Thanks for the dyn file. But I’m still lost. 😐

I’ve demonstrated transforming a point from it’s absolute position to one relative to the Survey Point coordinate system. But seems like you intend to do the reverse
Swap the inputs for _fromCoordinateSystem_ and _contextCoordinateSystem_

Thanks a ton! You’re the savior. Easy to track thousands of such points now. @Vikram_Subbaiah
