Hi Klaus
Thank you very much
I don't know what I would have done without the help in this forum.
Something that has struck me with your routine is that one could "extrapolate" heights outside your Tin Model. Where this would be helpful is say controlling the earthworks operation on a golfcourse. What I do is to take the coordinates from the Landscaper (Golfcourse Designer!) as he\she has designed it, convert it to a Tin Model and download it to my controller (Workabout_pro)
Then in the field I hold the Prism Pole (Robotic Total Station
) or the Rover Pole (GPS) anywhere on the site and the program will tell me how much up or down the groundlevel must go, to tie in with that of the designer. The design height gets calculated from the respective vertexes from the triangle in which the Pole is held.
What I will do is to change the program that it will also give me a height outside the Tin Model, but warn me (or the user) once the Prism Pole is outside the Tin Model limits.
On another note. I am busy changing the storage format of the CAD program and will post it as soon as it is finished.
Thanks
Michael
