Making a groove/slot in 1st component for 2nd component which have complex movement and shape

[Anonymous]

First of all SORRY FOR MY ENGLISH. Let me explain the problem: for example i need to rotate cylinder from 90 deg to 0 deg with cutting a some box to make a groove for moving cylinder:

Its very easy to do! BUT how to make a groove path for rotating object which have complex shape? For example like this:
Of course some of fusion experts can say something like: "you need to make a shape's max points projections, rotate this projections around axis, make a sweep or a loft, cut box with that sweep,...blablabla,...but what if this object with complex shape also rotating in 2 directions while "grooving" the box? or sliding while rotating? (i even cant create a picture for this situation....cuz im new)

Even by math calculations its very hard to make a "cutting path" for complex movement of complex shape. So my question is "how to cut a one component by second, which have COMPLEX shape and COMPLEX movement? probably by simulating joints movement? by some other fusion-360 instruments?".

Please help!

You could try this:

1. Create a motion link between the two joints controlling the motion.
2. Drive one of the joints in very small increments.
3. Use Combine/Cut at each increment. (You may need to create create a new component each time and also save the tools.)

Is there a silhouette projection tool somewhere in Fusion?

Can you File>Export and then Attach your complicated *.f3d example here for experimentation?

This is some kind of solution BUT unfortunatly this solution can give me only "rough approximation" of true continious grooving path. I need to find a way to get something much more closer to true groove path instead of creating 1000 increments

Yes of course, there you go: 2 files.

1) Complex shape and "easy" movement

2) Complex shape and complex movement

The first one is just a simple revolve after projecting the body to a sketch:

I would use the API to create a script to do the complex one.

Probably the API script is the only thing which can help (but i dont know how to write it cuz im not a programmer)

Revolving projections DOESNT solve the problem for any complex shape( only for some sort of).

For example lets edit previous body - it will have same projection but .....:

Sorry for such ugly example but be sure - there is an infinite ways to create a really complex forms, which's groove path is different from path generating by revolving any of it's projections.

I made a mistake somewhere and have to go back and find it - but I assume that something like the Attached is what you are after...

@TheCADWhispereryour first idea about cutting a body with small increments is correct, but for getting true groove path the increment should be an "infinite small", like "dx"

But what about projections - as i wrote before making a true groove path is not only about revolving some projection of body

By the way, @TheCADWhisperer do you know where i can suggest an idea for instrument to fusion360 developers? I suppose adding this standart tool to make grooving paths for mooving components will be a really cool !! instead of making a hemorrhoid for users to solve this problem individually every time

I did not make any such suggestion?

In my previous example I attempted to Sweep-Boolean Cut one solid body with another solid body, but I accidently introduced an offset in my sweep path.  (Image from Autodesk Inventor Professional.)

Screenshot from Autodesk Inventor Professional looks pretty correctly about what i want to get (at least for simple movement but complex shape). Fusion 360 doesnt have body sweep, only sketch/face sweep
