Circular Patterned features / mismatching outcomes

[doncawley]

Thanks for taking the time to help!

I'm suuuuper deep into a model and realized an error much earlier in the timeline I need to correct.  I have provided the file and reverted to the circle pattern tool step where the error first appears and deleted the " future" history.  

You will notice from "issue pic 1.png" that one of the six large pointed sections does not match the rest, even though all of them are created from a single patterned face.  Lets call the incorrect state the "Thin" version as it has thinner and 5 total steps, and the accurate version "Deep" ( with only 4 steps, with the top being wider). 

I don't know how to fix the issue and make all 6 sections be the Deep version.  Every time I attempt to edit to pattern tool, it wont allow me to select more than one object.  A workaround of creating it new, usually works but then I haven't been able to get the desired pattern. Either way, I'm dumbfounded how one of the six section can be different if I'm creating them all from a single pattern.

I'm sure I'm missing something but I'm too close to it.  Issue pic 2.png is what i've been able to create in a best attempt and that doesn't even match either outcomes from before.

I have updated the attached file.  See my next comment.

You have more time in it than I have.  

Which is correct? 

Your Pattern selected 10 extrudes, and in my view the only right landing is your thin one, something cuts off the other 5.  

That something is Extrude no 1, if you remove this one from your pattern no patterning anomaly, but you say it will now be incorrect.

Checking the sketch, I was unable to deselect the top triangle from extrude 1 selected set - almost as if there is no individual profile, but in the sketch I can select those as individuals.  Leave you to decide what to do.

So the big regions being cut in extrude 1 for the whole job, is being pattered, so patterning this extrude, works, there is only one thin landing in that extrude, and when done there is still only one thin landing, it just means it has moved.

Might help....

You are correct in the confusion.  It seems I have patterned the thin version and somehow ended up with 5 of 6 deep versions.  I want the deep version.  How I ended up with that version, I have no clue.  While I would be interested in finding out how that happened, ultimately, I just need to learn how to fix my problem.  

I have attached a new version of the file below.  It should help make everything clearer.   How do I pattern the existing extrudes around the face of this circle?  I believe it needs to be patterned around the X axis 6 times using the feature object type. 

Thank you!

Whenever you have symmetry, it's a good idea to use it to your advantage.

Here's the result (ignore the wrong selection for the center😁😞

Here's the pattern:

And the base sketch.  Note: The right side was mirrored to the left.

Thank you @etfrench .  I have a pretty good idea of what the final product will look like already.  I am looking for guidance here to learn how to make it in fusion.   I'm not sure if I missed something in your post but I seem a few images and no instructions or files.   Can you elaborate as to the process you used?

I did this model in another thread, the same way Ed has abbreviated the method here.

You should have my timeline to follow the steps.  

Use a sketch of 1/12 of the pattern (30 degrees of it - did not mirror the sketch)

make the pie section with various Extrudes.  

(Or other suitable tools - partial revolve / sweep comes to mind)

Mirror Body, to create 1/6th model,

Pattern that body 6 times.  

Combine to make a single body.

Might help...

Thank you dave.  I used a similar process, utilizing the symmetry of the model and was stuck at the patterning of the features 6 times. 

While process you described should also work I ended up better understanding your original callout and edited extrude #1.  This corrected the design and allowed the pattern to work appropriately.

It's so simple, I didn't think it needed any more explanation😁 In the sketch, select all of the profiles for one layer, then extrude them as a separate component. (This makes it easier to see the results, but isn't really necessary.)  Repeat for each layer.  Combine all of the bodies after patterning them.
