Circular Pattern making one less quantity

[eugeneallann_corpuz]

Beginner to Fusion 360 here, I'm currently trying to reproduce a swiss toolkit and most of the tools have these specific curves leading into the tip of the tool.

I've somehow successfully created the cut by lofting on each face, but when I create a circular pattern to make it for all edges, it only makes a quantity of 3, instead of the selected 4. What is my error? Do I have to tiresomely just manually add in the 4th one?

Edit: Attached the F3d file. Prof didn't tell us we can save files locally so I didn't even know f3d files exist. He actually just told us files are only saved through the cloud. That's my bad. The particular body is called "Hexagonal Screw Big".

Hi,

Impossible to tell without your file. Please export it and attach to this thread.

Cheers

Select the axis, not the edges.

looking at your pics, it's probable that the asymmetrical nature of the loft is causing the last instance to fail.  loft should fail in cases like this, but sometimes it just does what you're seeing.  check the symmetry of your input curves, (or attach your .f3d so someone can have a look and not guess.)

Hi! Try expanding the Circular Pattern panel -> Compute Method -> select Adjust. Does it work better now?

Many thanks!

[eugeneallann_corpuz]

Sorry for the late reply, here is the f3d file. The body is called "Hexagonal Screw Big". Our professor didn't even teach us that you could save Fusion 360 files locally (lol) and that's why I had to take screenshots, sorry bout that.

I've managed to make the feature with little hassle with mirroring it through planes, but I'm leaving this here for future reference. Many thanks!

[eugeneallann_corpuz]

I've already tried to cycle through the compute methods prior to asking this question. The adjust method did make a 4th feature...but one of the arcs returned a 45 degree cut instead of a curved one like I wanted. I've already replied to one of the comments with an f3d file if you are still interested in knowing why. Many thanks for the reply!

[eugeneallann_corpuz]

I did select the axis when I posted this. It wasn't clear because I didn't take a screenshot of the panel. It still happens. So unfortunately, not the reason why it wasn't working.

[eugeneallann_corpuz]

Sorry for the f3d issue. Edited the post to include it. This might be it, but as a neophyte, I couldn't find any better way to cut the curve without lofting the way I did it. Currently struggling because another tool part like in my post with a smaller tip but has a different curved cut (attached picture). Probably really getting further from the point of my post, but what's actually the best way to do cuts like this. I can't seem to find a definite solution from the internet.

Thanks for the help!

Every one of those curve cuts is a simple revove cut using the same cutting profile.

[laughingcreek]

see attached for an example using revolve for the cuts.  like I said before, all the curved bits are revolves like this.

fwiw-extremely surprised your professor would have you modeling a multi-part tool with out using components.  you workflow would be greatly simplified if you modeled this as an assembly using components instead of a bunch of bodies jumbled in together.

also surprised the professor would allow the use of sketches that aren't fully defined.

I taught hundreds of students to become certified experts over a 30 yr career of teaching different CAD softwares.

Several won gold medals in competition.

Would you like to learn how to do this correctly (right now you are developing poor modeling techniques - this will hinder your employment prospects if not simply lead to unnecessary frustration)?

[eugeneallann_corpuz]

I finally got to make the cuts through revolve with your help. I still find it hard to construct the sketch needed to revolve (especially with so many parts I need to do this to), but at least it's way easier than how I've trying it.

With regards to the professor thing, this professor isn't very hands-on with how he teaches us our workflows. He taught us basic shapes and how we should strive to try and make our bodies with as little actions as possible, but didn't actually teach us tips on HOW to. He told us on our first meeting that he actually learned Fusion in an advanced manner compared to his classmates since he deviated from his professor, who allegedly was really slow in teaching. I think he's trying to impart a lesson that if we want to achieve some semblance, we have to learn it on our own, even if it means being really messy in the execution in the meantime.

This particular plate was also supposed to be very lenient for us, since we don't even have to do inner workings as long as the parts you can see is moving as intended. The original plan was we would bring a 7-part object (which most of my classmates are doing, 7 parts), and that is what we were modelling. I brought a nipper, and he rejected it saying it's way too easy. So I had to get something else on the spot, and my professor owned the toolkit and suggested I just model that (well more than 7 parts), measuring with a tape measure lol. Oh and he did teach us components, but he had taught us that we should try to make that our last move when we all have our bodies finalized. I wasn't aware that wasn't standard practice.

I'd say it's much too advanced for our 2nd week with Fusion, but he took a look at what I had finished earlier (I already made 6 of the tools) and seemed pleased it's as detailed as can be at my level and used a lot of tools that he didn't even teach us. Plus, he also modeled this toolkit, but with less details. I just think he likes I put a lot of time into attempting to do it at least. Incredibly messy behind the scenes though, as you said and I wish I could do it cleaner, I just don't know how to since I'm focused on just...doing the thing.

Wall of text, but I hope it at least provides context. Thank you for reading it!

[eugeneallann_corpuz]

I would absolutely love to!

As someone who likes to say he wants to make everything as neat as he can, I'm ashamed it is this messy. However, if this involves shilling cash, I'm afraid I'm a little short on that front, so I'll have to pass if that's the case :')

I apologize that I lost track of this discussion thread.

This is a free help forum.  Not charge for any help offered here.

Do you have a picture of the parts (or something similar from the real world) and we can get started on the best techniques to use.

(You will be very happy with what you learn.)

He posted a small picture of the product in Message #1.

@jhackney1972 

I only see Fusion images and a Fusion file in Message #1.

I do not see a picture of something from the real world?

I do not see a canvas image of something from the real world in the Fusion file.

With a picture of this toolkit, I would be able to offer expert help for free.

[jhackney1972]

Sorry, it is Message @#9.  It is not a very good picture.

[TheCADWhisperer]

Thanks @jhackney1972 

@eugeneallann_corpuz 

Observe as I start to go through this that there is a red lock symbol on the sketches in the browser.

Observe also the color of the sketch geometry.

These are two visual indicators that the sketches are fully defined.

Before I proceed - do you have more pictures of the Frame from different angles.

Once I have worked out a robust solution I will walk you through the steps. At the end of the exercise, you will be the best Fusion modeler in the class.

Keep your sketches simple and define to the Origin as datum.
