Thanks to all who got involved over the weekend with the issue I reset below. It turned out that Lars was right; the map I had received contained a part that really belong to the next UTM zone.
One thing should have been a good hint for me it but I missed the underlying implication. I had copied the table in a plain lon-lat, and done the creation of objects and they were perfect. Any geographic projection is good only for a limited "domain"; MI cannot be held responsible in a situation outside the normal range of a projection. Lesson learned.

I do that by extracting with ObjectNodeX..Y of 2 successive nodes coordinates and using the creatline() function. All that is done after setting the coordsys to that of the table. I have used the program in many occasions without problem but the above projection makes my program crash. The origin of the crash is that the created lines are not lying exactly over the corresponding "sides" of the regions. I have observed for one node (I guess it is representative of the situation) a shift in the X direction only: a region node at (872411.6012, 5819181.1726) is converted to a line end at (872411.6502, 5819181.1726). This shift of 4 cm about is enough to make my program crash --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 3192
