Hi Heiner, it may be difficult to do that for all cases - in the general surface-to-surface mode (if you have not checked the "Projective" option), the 2 surfaces do not necessarily need to be sitting one in front of the other like you show there, one surface can be way off to the side of the other. Also on closed surfaces the arrows would look somewhat strange I think, you would end up with 2 arrows both pointing to the same location on the target surface for things like this:
Trying to show mapping arrows for a case like the above would probably look pretty strange...
Or maybe I did not quite understand what you are asking for - I originally thought you meant Flow would show you these arrows to help illustrate how the mapping was happening... But do you mean you would draw these in yourself? Flow does already use the pick points for where click on each surface to determine how the flow will be mapped from one surface to the other, there's some detailed information on where to pick here: http://moi3d.com/3.0/docs/moi_command_reference8.htm#flow - look for the section with the red dots and arrows that show you the 8 key zones that you should target with your click when you select the base and the target surfaces. You need to carefully control the spots where you click on the surfaces in order to give Flow the information on how to match things between the surfaces.
