[mapguide-users] Polygons and Intersection Problem

[shreepadr]

One suggestion would be to repair the geometry of the polygons in ArcMap
If you go to tool box there is a tool called repair geometry, run that and
recreate the sdf file 
Second option is bring the shape file into AutoCAD and then create SDF from
there 
I had this issue before and when I repaired the geometry in ArcMap it worked
fine


Thank
Shreepad
