I am creating a fairly simple program that will create a part depending on the user input size. I am only having trouble using the InsertFeatureChamfer method when creating the part. The program successfully selects the edges that need to be chamfered, and the method does insert the feature, but it is not activated. That is, you can see that the chamfer feature is in the design tree, but it is not represented on the part. I then have to edit the feature manually and hit the green arrow, and the feature is created. This is my first automation project and have been using C# with visual studio to develop the program. Anyone have any ideas? I am sure it is some simple error I am making. I have included a screenshot of the code.
