[fdo-users] How to get feature class extent

[Maksim Sestic]

Hi Bruno,

If everything else fails, you can always resort to the brute force approach
:-) 

1) Create a calcEnv variable to keep calculated IEnvelope (initial size is
0,0,0)
2) Fetch an instance of IFeatureReader you want envelope calculated for
3) Iterate reader, stretching up calcEnv using IGeometry.GetEnvelope()
4) At the end, calcEnv keeps actual 3D envelope of the IFeatureReader
feature instances 

P.S.
IEnvelope = 3D spatial extents of a geometry

Regards,
Maksim Sestic

Is there a way to get the actual extent of a feature class.
I know we can get the spatial context associated with that class and request
it's extent.
But as many feature class can share the same spatial context, it's not the
actual result i'm interested in.

Thanks Bruno Scott
