Issues with arrange in manufacturing model

HarrisonClassic — Sun, 08 Aug 2021 07:04:05 GMT

So reasonably large model for sure, but I think I've reached some sort of internal limit in Fusion 360 and now the product is not behaving properly, again...

Created a manufacturing model and am using the large perimeter as the plane for arrange to apply to.

As I've been adding components, they have been placed in the bottom left corner and then I've moved components into the area I'd like.

As you can see now even a small part is not able to be added to the arrange, I've even edited the sketch to make the boundary much bigger, still the same issue. It seems to want to put it on the wrong plane even.

Thinking this is Fusion just not able to handle it, I created a second manufacturing model, a new sketch for it and tried adding the same part, still no luck. I then tried adding parts that I have successfully added in the first manufacturing model and the arrange just overlaps parts not trying to arrange the at all.

I ran another arrange selecting parts in a group, and got a different result where not only is there overlaps, but it orientated a part incorrectly also.

This suggests to me that building a manufacturing model with more that a few dozen parts is not feasible.

Can anyone offer advice to whether this is in fact some sort of hard limit.

Perhaps multiple manufacturing models with few components to arrange might work? At least it's only a days lost work potentially...

I'm starting to get a little concerned as I've invested a year into Fusion, discovering numerous bugs and behaviors that are just not right, now found issues in manufacturing, haven't even got to see how robust the toolpath creation process is....

Is Fusion 360 just not ready for such work?

Love to try and help but I need your model, maybe the second smaller one. Please attach it to a reply post. You may have to use the "Reply to post" area to find a way to Browse and attach your model.

Thanks John, let me try a few things first.

Unfortunately the "second" model is the same as the "first", just only showing around a dozen of the components 😉

I made a post earlier about a body continually reappearing and relocating when the Compute All button was pressed. I did in fact make this go away by deleting that individual sub component and recreating it, then the problem went away.

The components I'm trying to add via the arrange command are from the same parent component.

I suspect that there is some sort of corruption contained within the document relative to this parent component. that is not getting highlighted when Compute All is run. I'll investigate this today.

Sometimes I feel with Fusion that there are just so many bugs, and model integrity is poor with large models ( 250+ components, 200+Mb in size ) and it's just a matter of time before a problem arises and you can't proceed.

@HarrisonClassic

thanks for the feedback, do you still see the problem? if yes, is it possible to share your model, then we could check it? thanks
