Split object with wavy path along existing path?

[login]

I need to split an object that will create a wavy joint, as opposed to a simple butt-joint. As a simple example, I created a tube and a fan for a splitting tool.  You can see that once the tube is joined it cannot be twisted due to the wavy joints.

I have a more complex tube, lofted together via sketch lines as seen here.  The attempt you might see was just me creating a simple ½ arc splitting too and copying it multiple times along the path trying to create waves along the path.  That isn't really a way to do this, but it shows what Im trying to do.

Any idea how to make a wavy split along a 3D path?

EDIT: I was asked to post the f3d file.  That file was simply used to mess around with, and is not my real file. It was never meant to be shared, so it's full of weird stuff.  The point was to show a picture of what Im trying to do.

Would have to know more specifics, 

Try a very thin solid segment of one tooth of the cutting shape, 

Pattern on Path

Combine Join, 

Split body with one face / side of the cutter.

Might help.....

Hi,

Please share the file.

f3d attached to original post. You can ignore most of it, it's a junk file, just interested in the lofted object and how to split it with some wavy lines if possible. Thank you!

Your sketches are blue --- not good. measure them.
Fix the oval polyline sketches if you don't want them to be changed.  br  mango

Well, still haven't figured out how to do this.  It's probably not possible. :(. For now, Im just using my original idea showing a cutting wheel.  But that only produces acceptable and predictable results when slicing a cylinder. To anyone looking into this in the future, if you look at the image I posted, you will see an 'S' pattern along an existing path, and following in the direction of the path.  The path is the blue sketch line that was used to generate the loft.  Something like wrapping a sketch around an object or along a path would be what I'm looking to do.

what is missing from my last solution in your eyes? i showed you a simple method. then where is the real center of your work, or how many teeth and their depth should it be?

I appreciate your trying to help.  It's made me realize maybe the cutting wheel was the best/only solution from the beginning.  Your solution was using the same method I used in my own example, correct? It was another cutting wheel. It just had a different profile. Well, OK...  But the post was asking how a *wavy path* could follow an *existing* path.   The wheel cutting method I originally used, creates its *own* path, and again, the cuts it creates are not good unless the object being cut is a cylinder. I'm cutting an object that's being lofted by 2 sketches, so it's not a cylinder.

Cutting wheel method on non-cylinder objects creates issues.

now i understand you @login  it's not perfect yet, but it's close. maybe it is better to emboss the profile with emboss. and then only every second with a straight connection. br mango

Hello again! Yep, this was my 2nd method/attempt as seen in the photo and attached file in my original post and a close-up seen in this reply. And this is where I stopped and decided to post here because it was going to be a very manual process at this point and I was hoping there was a better way.  So it looks like you got to this point as well using a similar method, and decided to loft between the copies. Not a bad idea, and yes, it does work.  I'm not sure how many of these lofts I would need in my real file. A lot!  Like I mentioned, the files and photo posted here were just for a visual explanation. My real objects are more complex.  😞  Here is the close-up of the file I attached here using the simple example object.

Looks good Mango. It's a very manual process with lots of lofts in my actual, real-world object, but I will see if I should use this approach, that I originally started, and you decided to complete using the sample but simpler object.

Your loft is a surface, I would make the cut into that surface loft, before thicken in the timeline, you will then likely find the construction of the cutter much easier.
