Pattern - Linear?

Anonymous — Sun, 30 Sep 2018 04:36:23 GMT

Hi,

I am very new to Fusion 360, but have almost 20 years with PTC products and Solidworks. I am learning Fusion 360 for some fun home hobby stuff. I fish, so I thought it would be fun to model some fishing lures as practice. Starting with the plastic pink worm, and got stuck on how to pattern a revolve cut to make the segmented ribs... This cut follows the same central axis, but the diameter needs to adjust to the outer profile of the worm body. A bit stuck, and have some odd results thus far. Attached is a pic of the worm I am trying to create. If I pattern along path, and the path is the outer profile, then the cut doesn't fully cut, and if I use the center axis as the path, well that sucks too.

Thanks,

Westy/James

Normally I'm saying, that feature based patterns should be preferred over sketch based patterns - if possible. But this might be one of those examples, where you have to use the sketched based pattern. Sure - there is no Pattern on a path, but as long as it's linear you can use the rectangular pattern.

If this shape is not base on a line you have to either draw it manually or the sculpting workspace might be an option (but I have more ore less no experience with that).

Can you share the model , I can give a try with model .

Howdy,

Sorry, I guess I marked this as solved. But appreciate the tips so far. When selecting the direction, can you select a curve? As you see, the circles pattern off to space since I can't seem to select more than one curve segment.

So, to share, how would you like it? Being cloud based, this is new to me as well. I see I can send you a public link, but that is kinda weird, and if I send you a STP or IGES, then it is a "dumb" model. This is just a simple worm, did you see my last post? it is really how to make a pattern of a revolved cut follow a path, but update the driving section accordingly.

You could get very close with the technique in this thread by @PhilProcarioJr.

Attaching files: Files|Export|Archive files *.f3d then attach the file.

That was a nice tutorial, will use it in the future.

However, I still would like to know how to pattern this feature "correctly". This is a learning exercise to be used on future design projects, so I want to figure it out.

Thank you,

James

Okay - here is a workaround. Not clean, not nice, but... working

Create your main profile
Create cut out path and profile
Revolve main profile in the model workspace
Switch to the Patch workspace
Patch the cut out profile
Pattern patched profile along a path
Switch back to the Model workspace
Use the faces as profiles and revolve cut them
Remove (not delete) faces (unfortunately not shown in the screencast)

The downside of the approach is, that if you change the number of cut outs the revolve cut will either complain a missing path (in case you're decreasing the number of cut outs) or new faces are not included in the revolve cut.
