Projecting to a curved surface and cutting out

[davieinvent]

Hi all,

I'm new here.

I've been learning Autodesk Inventor from you tube tutorials etc, so I'm certainly no expert.

 

I wonder if someone can help me.

I have been trying various ways to create a toothed detail around a curved surface.

Nothing seems to work for me.

 

I'm trying to create 2 separate parts that rotate and drop into each other, I need to cut/split along the line.

The cut needs to follow to the centre point and not parallel with the centre line, which is the problem I am having.

 

Hopefully this is explained properly.

 

Thanks in advance for your help.
