I haven't used Miter Flanges a lot in SolidWorks so I'm having some problems figuring out why Miter Flange2 and Miter Flange3 won't allow me to add the feature to both sides ofthe part. Is it the sketch I need to change? If so, I'm not quite sure how to change it. This is an inherited part that I'm updating so I'm not sure how these features were done originally. I thought I could just add edges to the miter flanges so it is mirrored on both sides but when I select the other two edges it won't add the feature. I was also going to delete Flange3 and just mirror Flange2 once I have it figured out like I did for Edge Flange1.
Thanks for the help!
