Thanks for checking in, Kerry. I wasn't complaining, just making note that no one had responded. I just figured I'd finally 'stumped the experts'
In my quest to solve this, I tried to incorporate an EntityJig using an MText with a BackgroundFill. This may actually be what I need, but I have yet been able to get it to work as desired.
Since I'm already using PointMonitor and TransientGraphics, to locate which object is currently closest to the crosshair, I thought I should be able to use that same MText object in the TransientGraphics and locate it adjacent to the crosshair......while the code runs without error, the MText is never displayed.
So now I'm back to trying to figure out the thinga-ma-Jig. In the currently working (using the AddToolTipText method), I employ the PointMonitor and a loop using GetPoint(). When the user sees the entity they want to edit, and move the crosshair towards the ends or middle, they are presented with options that will affect the object, either the endpoints or the the slope from one end to the other. Once the entry is made the object is updated and the user is returned to the GetPoint() prompt. All the while the PointMonitor is running. Try to duplicate this behavior with a Jig is seemingly out of my reach at this time, but I shall continue trying.
