CoordinateConversion widget - how to add z-value to added format which is not wgs84

Question

I'm using ArcGIS API for javascript version 4.18 CoordinateConversion widget to display mouse coordinates cocurrently for several cordinate systems. I'm following ESRI's code example in CoordinateConversion widget - Custom Formats page.

This page shows how to add 2 new formats, one is wgs84 with "z", the 2nd is some TM format.

I want to add "z" also with the 2nd format, but I have not succeeded, as I'm new to this area.

I'll appreciate help.

Hi @MichaelLev, I think there are two answers here. First, it looks like the second custom format (spatial reference: 102241) does not support the vertical dimension.

But if it did support the vertical (z) coordinate system, then I think you would only need to add the z: parseFloat(parts[2]) to the state plane's conversionInfo.

Hope this helps!
