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?
In general, there is no way to implement the user interfaces for feature creation or editing into a macro or add-in.
You can draw your own graphics on-screen using OpenGL, or you can have the user create a coordinate system before they activate whatever function of your add-in needs one.
