Rigid group and subcomponents

Hi, I've a question that maybe have not a solution about rigid groups in hierarchy

 

I´ve a cabinets where I can change parametrically how many hinges are mounted depending from the heigth of the cabinet.

 

I construct in the timeline in a way that the array of the hinges is inside the same group of the door and I make a rigid group about all components inside (with include subcomponents). It works and is not a problem if the number of the hinges is the same but if I change the heigth of the cabinet and the hinges become more than before, the rigid group do not contain the new hinges also if are in the same herarchy level of the other. That means if I had before 2 hinges and later 3 when I move the group of door and hinges, the new hinge doesn´t follow the group.

 

Have someone an idea if there's a solution of this that is not manually edit the rigid group manually? The problem is that do not show any error in the timeline and I´ll forgot to modify it with all the following problems to have an hinge flying around the model.

 

Hope I explained myself

Hi,

Place the hinges in a subcomponent "hinges" of the assembly „door“ instead of a rigid group.

If I understand well what you mean, I´m pretty sure that this will not solve the problem because the hinges are still individual components, also if they're in a different hierarchy, because the command take the subcomponents at the moment of the design but it continue to keep the list of components instead take the all the subcomponent. But I can try again if Fusion decide to give me access to the file that is trying to upload from 1 hour, I don´t know why.

@g-andresen how does that address the problem described by the OP?

Each and every time you adjust the count in a properly assembled component pattern you’ll have to manually adjust the joints afterward to either add the new component(s) to the selection of the rigid group, or rPepair the yellow icon that the rigid group has become.


After severally years of no progress in the pattern tools, now they urgently need an update!

The only "solution" that I know can works is to make the hinges bodies instead of components. The problem is that I have a working structure that count components in BOM for know how many hinges I need and how many panels etc. If I make bodies it will not work and I need to change all. I wonder why Fusion works like this but I guess now they cannot change it.

Creating bodies instead of components is a not  good idea for a number of reasons.

 

Of course that can change it. This has been discussed a number of times., It just hasn't bubbled to the top of the priorities.

I'm not exactly sure that they can change it without break some way to work of other people, at least they need to add as new functionality. For sure add this kind of function would be a great way to solve many of my headache and it had avoid alot of problems to understand the program in my early stage. Fusion 360 is very powerful but sometimes is really difficult to understand how the timeline process of recalculate the model work or doesn´t work.

As a user of a lot of CAD and 3D modeling software for more than 3 decades I can tell you that this can and should be changed and rather soon. The CAD software that Fusion 360 aims to compete with has NO problems with this. I have uses one such software package since 1998!
For a parametric CAD software that wants to compete in an already crowded space of mechanical and machine design, the current pattern functionality  is inadequate! 

 

You also mentioned BOM's and those only count components, so there is really no workaround. I have resorted to use OpenBOM ( I am a paid subscriber) even for my "hobby" projects, because Fusion 360's native BOM abilities are rudimentary at the very best.

I guess we're going a little OT, but is nice to talk.

I used CAD since AUTOCAD 11-12 in DOS version and before I used also Dynacadd on the Amiga for very simple stuff.

The problem is not to change the software but that if they change the way it works, probably there will be some users that will have some solutions that will not work more.

About the BOM I use a Python open source addin and I modify it adding functionality, counting bodies instead components would be not a real problem but I need to change all my libraries of models.

I don't think that is the case. The Fusion 360 team is also aware that his is needed and we've had some discussions on the Autodesk Expert Elite Slack Channel. Technically this can be done without interferring with existing models. There are different approaches.

IMHO a number of timeline features could work not only parametric, but "procedural" like the nodes in SideFX Houdini, where information from one note is transferred to the next one. In this case that would be the instance counter in a pattern node/feature which automatically is updated in a subsequent rigid joint node/feature.

So, if they know how to do it´s time to do it. 🙂

 

Would also be nice to have a more stable software because drawing section and derive components still does not work very well.

If you have examples of instabilities, you should post them. They look out for bug and crash reports here on the forum and often if I come across such posts/threads I tag one or more members of the Fusion 360 team.

I know, but is time consuming to register all the stuff and recreate the bug. I made many times before and I start to be bored. 🙂
