I am trying to generate a cam slot in a cylinder, however, I cannot figure out how to go about getting the correct geometry.
In Solidworks I would have used a sweep 3D object I believe.
As you can see in the attached blueprint it is generated with a 0.3165" diameter theoretical cylinder "end mill". It is rotated 21.5 degrees from the center of the main cylinder body over a distance of 0.255".
I have tried emboss, I have tried projecting a slot on to the cylinder, then using split followed by a thicken cut. It does not provide a "straight" geometry from that point.
I have also tried doing a sweep command however as you can see in the "Sweep" attachment" it does not give the edges of the cylinder.
The only method I can think of, yet not sure how to implement is a pattern of extrudes that only approximate the curve. I want to stay away from this method because I would like to be able to keep the design modular for later changes in main body cylinder diameter.
Hi! Inventor is not yet capable of sweeping a 3D volume. The closest approximation is using a 2D projected profile and sweep along a path guided by a surface. We are aware of Solidworks' ability to sweep a 3D volume. We are investigating similar capability.
In the meantime, there are two alternative approximated workflows. One is sweep a projected profile along a path guided by a surface. The other one is pattern along a path. If you need more information about the first one, please post the part here or send it to me directly (johnson.shiue@autodesk.com). I can show you how to get the approximated solution.
Many thanks!

Have you attempted this in SolidWorks?
If so, can you attach your SWx file here?
I think you will find the solid sweep on path more limited than you might expect.
I would do this in SolidWorks the same way I would do it in Inventor.
Can you attach your *.ipt attempt and/or *.sldprt attempt here, or at least indicate what version of Inventor you are using?

Are you still there?
I can give you a full-feature parametric solution if you are still trying to figure this out.
