Hello,
I'm trying to select these planes to work on, but I cant select them... How can I do that?
I've tried to ad a plane, but when I extrude a circle nothing happens.. See attached video.
Well, i made started with a 2D sketch, made from a circular pattern. Then I extruded it:
Ok, So looking at your model, you have a sketch on plane 3 which you are extruding towards the centre of the rotor 7mm. currently you are trying to add that sketch profile to the rotor hence no change in the model. Presumably you're wanting to remove 7mm of material from the rotor in which case you need to change the boolean option from Join to Cut; see the image below, the circled icon is Join and the one to the right of it is cut.
If you want to add to the rotor then I presume you want to extrude out and away from the centre in which case switch the direction with the arrows above the 7mm distance entry.

you can only create a sketch on flat/planar faces, those faces are round with a large radius close to almost flat but not 100 percent planar, the only way you can add a feature to those is by sketching on a workplace and extrude to that round face.
Adding :
Removing:
Make sure when using cut, do it in both directions, cause there is material on both sides of your work plane, and if you just cut inward, the cut won't show since it's blocked with the material on the outside of the work plane.
Hope this helps
