Curve driven pattern : face selection

Hi,

I am trying to create a curve driven pattern using ModelDoc2::FeatureCurvePattern (VB.net). I was not able to get the face included in the pattern. The pattern is able to create but the Face is not included into.

So, I recorded a macro to verify the mark value.

Edge: mark is 1

Feature: mark is 4

Face: mark is 1024

If i try to run the macro again, i got the same issue. the pattern is created but the face is not selected.

is it a bug with api ?

PS: anybody knows the difference between FeatureManager::FeatureLocalCurveDrivenPattern and ModelDoc2::FeatureCurvePattern ? What does mean "Local" ?

Thanks for any idea.

Regards,

Cedric
