I'm trying to make custom Routing parts, and for the most part everything goes smooth. 

The system recognizes I have a Elbow part (See Picture1 and Picture2). But when I try to close Sketchmode, it gives an error that the Elbow fitting does not have to correct configuration, and gives a list of specifications the fitting needs to have (Picture3 and Picture4). 

However these are exactly the same dimensions as my part has...

I also added a picture of the Design Table of my Elbow part (Picture5).

Does anyone else have this problem or know a solution?

* Note that the part is Derived from a STP file, but with my knowledge this shouldn't matter as long as the part contains all the sketches/configurations etc required to be an Elbow.
