I have used a table with the �Universal Transverse Mercator (WGS84) Zone 32 Northern Hemisphere (i.e. 8,104...) to build lines over region borders. 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 I seem to remember that someone wrote about a similar case, and that it was due to a fault in this projection model during the coordinate conversions to read in the values and to insert them back in the objects. Any confirmation of the problem would be greatly appreciated. Jacques Paris e-mail [EMAIL PROTECTED] MapBasic-MapInfo support http://www.paris-pc-gis.com
