See the attached pdf for a description of the convert entities bug in SW 2016. I reported this back in SP0.1 on 11/18/2015.
This resulted in a bug report to be written by SOLIDWORKS. (SPR#923109)
I reckon the team has been too busy fixing colors.
Here is where the sketch flips from the inside edges to the outside edges, leaving the one edge that had an overlapping line segment with a line still on that edge
Why are you selecting the edge and the face? Why not just the face?
The functionality of the software always allowed you to convert internal edges this way, not just external edges. That is why you would select the edge and the face. Maybe you have always been an internal edge selecting guy, ctrl clicking every internal edge, but up until 2016 it worked flawlessly.
Did you try the select all inner loops?
The solution you offer is a potential work around, but:
1. It forces you to invoke the convert entities command before you select anything.
2. The way you present it would not work. If you had face 1 selected, and then hit select all inner loops, you would get face<1> and add loop<1> in the entities to convert. If you hit check here, it would put double line entities on every internal edge.
3. You can have the inner loops one by one box selected, and it will make just the inner loop...so, this works, but this is not the way the software always worked.
I have convert entities on a hotkey combo, and having to invoke the command first, check the box, and then select and edge is just cumbersome. They broke the fundamental way it worked by trying to add this functionality to the convert entities command.
I'll live with it, as I have been, but it has messed up my SolidWorks Kung Fu.
