I'm using an arcpy search cursor to access a Oracle database. I have a simple Python class that I copy the returned row objects into, which gives me more flexiblity than the cursor.

The problem is that although I do nothing at all to the point geometries from the cursor, they do not intersect with the original point when written to a featureclass. The geometries themselves remain untouched during the whole process.

Any ideas?

When you say they do not intersect with the original point, do you mean, they are placed away from the original points? If so, is it uniform, or random? Have you checked the coordsys of both sets of points? –  Hairy Jan 24 '12 at 10:59

Roundoff problem? –  Stephen Quan Jan 24 '12 at 12:02

When you write out the points are you writing them to a geodatabase? If so it could be the ArcGIS snapping to the grid issue. If not, then I'd look into the roundoff error as @BicycleDude suggests. –  om_henners Jan 24 '12 at 22:04

Seeing your code might help. –  Chad Cooper Jan 30 '12 at 14:25
