Possible "bug" in auto-recognition of profiles in a sketch

[oprcmr00]

I cannot select the internal profile of a surface. I have the "auto-project geometry on active sketch plane" on, but it doesn't work. Even after the projection it cannot recognize the partial profile.

Am I missing something? I think it's a bug.

I imported this file (a piece of a 3d printer) that I'm trying to edit from the internet, it's not my production.

I do not see any issue using the Project command on your part.  As I mentioned, the Preference setting "auto-project geometry on active sketch plane" may be hurting you since the auto created sketch will get in your way.  I do not believe their is any Bug here.

Thank you. I would like to further ask: are you able to select this ↓ profile specifically (contoured by the yellow line). I am supposed to be able to select it, but there is no way to do it.

In this picture, for example, I extruded a random sketch with similar characteristics, and I am able to select both the internal empty profiles and don't even need to project them. In fact in the third picture, I can extrude them.

... → But this is not possible with the first.

Can you make sense of this?
