I must lost my mind. This is should be simple. please forgive me.
In AutoCAD, we can type UCS, new, then create a new UCS whatever you want.
In C#, How I can do it?
I found how to create a UcsTableRecord just like create a new layer. but I have no idea to set the UCS I just created current.
At autocad command line, I can type UCS, Restore, and then the name of UCS.
In VBA, ThisDrawing.ActiveUCS = ... do the job.
I would not use SendCommandToString.
Is there any thing I am missing?
