Hi, everyone.

I'm processing the Fillet Features, cause common Fillet Feature is creating on some edges, which are from previous Features. So, given a selected Fillet Feature, I wanna get the previous features related to the edges. However, I find the ISimpleFilletData has a function called Features, but as below, the Fillet is based on the Extrusion Feature, but when I call .Feature function, the returned valued is 0 or null. So, can someone help explain the use of this Features function, and what should I do to get my target?
