ArcGIS Pro: 3D cartesian coordinate system

Question

Hello Geodesists,

I am receiving data from custom 3D cartesian coordinate system I would like to define in ArcGIS Pro.

I computed the seven parameters to a 3D national system and there are equations to go from 3D cartesian to geographic that I believe ArcGIS Pro knows ?

It seems like I can define seven parameters method tranformation in ArcMap:

Equation-based methods—ArcMap | Documentation

But I can't find a way to define a coordinate system as 3D cartesian.

Did I miss anything ?

Thanks

Hello @MelitaKennedy,

Just wanted to tell that it is disappointing that it is not available in the softwares as it would be really helpful to manipulate CAD and BIM data using generally a random 3D coordinate system.

Is it something planned or not at all ?

Thank

Thanks for your reply.

I am not sure to understand: can it be somehow extended using Esri projection engine ?

Thanks !

We don't support 3D Cartesian in ArcGIS yet. It is in the Esri projection engine, but not exposed in the software using the library. I'm sorry!
