Frame Generator Miter Cut with Gap Eliminates Custom Frame Features

[petestrycharske]

All,

I have been working to build an assembly using frame generator, but have run into an interesting snag.  When I publish my custom frame part, there are two different versions (managed with an iPart table), one with a little alignment leg and another without one.  At the base of my assembly, I choose the versions of the frame that have the legs and can position them as desired. 

However, when I try to apply a miter cut with a welding gap, the alignment leg disappears on one of the frame members.  At first I had modeled the leg on a sketch offset from the square end of the frame member.  Next, I had modeled the leg from a mid plane sketch, while referencing the square end of the part.  Finally, I modeled the leg from a mid plane sketch with all new geometry.  I have even tried changing the order in which the members are selected, but none of this seems to make any difference. 

Can anyone please let me know if I have modeled something incorrectly?  Would appreciate any advice at this point.  Hope all is well and have a most blessed day!

Miter with Gap Eliminates the Leg

Miter with No Gap Works Fine

A Classic one.  Remember inventor is historic features based, so you need to reference to geometry that exists in your or every situation.

You have defined a workplane from a side face. But after using mitter the side face is changing.

To get is stable use in parametric library part planes that always exist. use the orgin planes as definition.

I redefined your workplane, publised to CC and tested it, it works fine.
