How to join bodies made using pattern

Anonymous — Thu, 11 Mar 2021 00:42:38 GMT

I made identical bodies using the circular pattern function and all looks good in fusion. When I convert to stl and then slice it, it has random voids in it and extra lines. When I convert it to OBJ and slice it, it gets rid of the voids but the bodies print separately. Join doesn't seem to work on patterned bodies. Anybody know how to do this?STLSTL after slicingComponent in fusion 360Trying to print sliced OBJ

Combine > Join,

Select one to join all bodies onto it.

Might help...

That's the problem. I can select any one body as the target body but then it will not let me select any others as the tool body. The patterned bodies act as one body but are not joined. There doesn't appear to be any way to join them.

Here's the fix I would do:

1. Move the timeline before all the copy and pasting

2. Delete the pattern you made from the timeline

3. Fix all the errors that creates

4. Repattern the two bodies(not components)

Then everything should join no problem, in the end you should have a Top and a Bottom component without all the sub components inside the two components.

Well, that provided some truly bizarre results. First I hid all but the original body the did the pattern again. When I sliced it it came out completely different on each layer. So I went back and tried deleting all but the first body and then doing the pattern and tried STL and OBJ. Still bizarre and the same file came out different in each format. Screen shots attached. I guess I'll try Joshua's approach next. And thank you both, I really appreciate the help. I've been teaching myself fusion for a couple of months now and this is the only thing I haven't been able to solve.

I should have also mentioned that after I did the pattern I did successfully join the parts but it still came out weird.

Looking at your file, one problem that comes up is that the components are all dependent on one another. So that means that any change to the component is pushed to the other components. In the future using this work flow you should consider using Paste New it will place a new component without that dependency.

I did what you suggested and it worked for the top half but the bottom half still shows 8 bodies after I perform the join. I've tried a few times but I'm obviously missing something and I can't see what it is.

I'm not sure I understand it either, but try this and hopefully it works on your end.

1. I deleted the first and second c&p in the first blue circle

2. then I deleted c&p in the second blue circle

3. finally delete the last union and repeat it.

Then everything came together for me.

Look through the timeline of the attached model and see if you can make sense of it.

I suspect you'll have many questions, so don't hesitate to ask!

In your model the last combine only combined 2 of the 8 bodies.

I only used a single sketch:

and the timeline is much shorter:

That did it. Thank you both for your time and effort. I appreciate the help.

Thank Peter, just saw this. I'm trying to do more complex designs to get past the nubie stage.

Re: How to join bodies made using pattern

TrippyLighting — Thu, 11 Mar 2021 20:28:00 GMT

Understood, but adding complexity before you've gotten down some of the basics is really not a good idea.

If you design complex stuff using your approach so far you'll run into trouble.

I want to step in here to address this question/issue:

This is a bit of an admitted workflow issue, and we do have a bug logged to fix it. However, you can do this. The problem is that Fusion hides the body once it is selected, and body visibility is shared among component instances. You can still select them, though, you just have to know where they are...

So, I would NOT recommend Paste New or patterning bodies, if you decide you do want to keep these as components. That might not apply in this situation, but can definitely apply in other situations.

The screencast below illustrates how this works.

That's a great tip, Thanks Jeff!
