C# InsertMirrorFeature2

Guys,

How to use int C# the InsertMirrorFeature2?

I used this code but nothing happens.

I want to Mirror a particular assembly.

  swDoc.Extension.SelectByID2(this.comp.SelectID,"COMPONENT", 0, 0, 0, false, 0, null, 256);

  boolstatus = swDoc.Extension.SelectByID2("PlaneX", "PLANE", 0, 0, 0, true, 0, null, 2);

   swDoc.FeatureManager.InsertMirrorFeature2(true, false, false, false, 1);

thanks in advanc

Regards,

Gab
