I'm developing an Addin (C#) where the user needs to create a coordinate system and select some other settings.

I'm using a property manager page, and I can create selectionboxes to allow selection of a point and 3 edges, then use createCoordinateSystem method.

However I would much rather use the SW built-in coordinate system editor, as this shows a "red-green-blue-arrows" coordinate system indicator and has "flip axis" buttons implemented.

Is there any way to activate the built in coordinate system editor using the API?

Or alternatively any way to get the same "red-green-blue-arrows" indicator of a coordinate system?
