Highlight hidden geometry & flip Dynamic UCS
1) With no command active, rolling over an object highlights all of its geometry, including hidden geometry. Is there any way to keep that highlight active once a command is started?
2) Is there any way to flip the dynamic UCS to something other than what it defaulted to?
The image shows the hidden point at which I'd like to center a circle in the displayed ZY plane. Once I start the circle command the highlight disappears and I'm left to guess where that hidden point is and use TAB to flip through faces to regain a highlight. By using numerous TAB's I can home in on the point for the center but the dynamic UCS is wrong since Circle will create in the XY plane. I'd like to just keep flipping the UCS till it's to my liking. Any way to do that?
I realize I could just change my viewing angle but that would entail zooming in again on a tiny area in a large drawing and then reacquiring the original view and zoom back in again to start the next command.
What I've been doing, using this example, is to select the lower member and positioning my cursor on the now highlighted point and then terminating the selection using the ESC key and manually entering the CIRCLE command so as not to disturb my mouse position. TAB, TAB, TAB, ... eventually shows the point but the dynamic UCS is wrong and I see no way to change it at that time.
If CIRCLE and the other primitives had the ability to accept which plane to use, that would also help.
