Ya i tried that as well the other day when I was working on it. I opened up the screen editor and looked at the display envelope push button properties and for action it lists for the down or up action, not sure which now, Display Tool Path. (I am recalling that from when I was checking it out yesterday so the exact verbiage for the action may be a little different, if it is I will update this post once I have a chance to verify.) I was looking to see if it runs a script or something that may need to be modified for something like a contrasting line color or something. I get the x,y,z coordinates and the two lines of the current x,y axis like you show in your picture examples but again I am not able to get a dotted or any line like you show for extents. My x and y soft limits are set currently at min of 5 and max of 350 and 570mm.
