How to work on this plane/face?

[vidar_hetlelid]

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.

Can you share the part file?

Sure, part is attached 🙂

How did you create the 'Fins' on your part? i do not have Inventor 2025, so i can't see your model tree. but I'm not able to select the face to place a feature. depending on the strategy you used, it may not register that face as a surface. this is only speculation for me at this point.

Well, i made started with a 2D sketch, made from a circular pattern. Then I extruded it:

can you try something for me?,

Go back and create 1 fin from the 2s sketch. then extrude that sketch, and add your hole on that face. then pattern the competed component.

when you use the pattern tool you cannot edit a child of that pattern.

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.

Hi there,

Ive tried that 😕  I did as follows:

And the result is this:

Sorry a few typos,

when editing a child of a pattern you can do that, but its a tricky operation. also can you send me a shot of your pattern dialog box please.

[mikejones]

What is it that you're trying to achieve? is it a cut feature or add material to the rotor?

[vidar_hetlelid]

I want to cut material from the rotor/finns 🙂

[mikejones]

So, you need to select the cut icon to the right of the join icon that I circled. The circled one is Join.

@vidar_hetlelid 

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
