cutout part of wheel (extrusion newbiw question)

[Anonymous]

very new to inventor and have a question regarding cuttting out a portion of the extrusion of a wheel/circle.  i would like to create a wheel with cutouts on the circumference where magnets will be inserted.  i know you can only sketch on a 2d drawing and since this is the arc of a wheel i am looking for direction on how to accomplish.  any assistance would be appreciated.

thanks!!

Create a sketch plane tangent to the wheel, sketch as required, and cut-extrude.  If you need the bottom of the hole to be curved (as if the piece were cut then rolled into a wheel in the process of manufacture) simply add-extrude an additional sketch (on a plane perpendicular to the axis of the wheel) to fill that material back in.

Attach your file here if you can't figure it out.

Hi thalex9,

See this link for an animation of how to create a Tangent WorkPlane (4th one down):

Once you have the workplane created you can sketch on it to make the cut.

Also, attached is a quick example file to look at. You can use the feature tree to examine how the model was created.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis
