replace component

javelin_exile — Sun, 03 Dec 2023 16:11:53 GMT

I have an assembly I'm adding components to. I have one part that needs an offset to use in 2 places. I created the new component joined it in place and realized the offset needs to be diferent on the second component, so I copied and "paste new" a version I can change that's not lined to the first but I don't see the replace component command. was it removed? or can it not be used in the timeline? Do I need to save it outside and use replace to put it in?

The Replace Component command is only available on Externally Linked components.

So you can't replace on internal components?

No, it isn't! As you progress through projects and get more seat time, you'll agree.

Okay, from your experience then, what could possibly be the advantage of not having this feature?

If Fusion 360 is more geared towards a top-down design approach then not having this feature seems to work against that.

Where did I say it is advantageous NOT to have that feature?

If you understand how top-down design in Fusion works, where it is so easy to have disjoint timelines and references multiple components, replacing a component is technically possible!

To replace a component, it has to be entirely independent of any other elements in a design. In that case, it is better to design it as a separate, external component.

So if I wish to use McMaster-Carr components and say, swap a bolt for one of a different length, I would have to download all bolts I think I may need in my design into a separate part design sheet in order to be able to use the replace function?

Well, I just came to point out that even for external components "Replace Component" has very limited use because it doesn't swap references, it just breaks them. If you replace something up the timeline - everything downstream that references it will break as the referenced objects will be gone. You'll have to rebuild the whole assembly from that component down. There's no interface or dialog window to help with reselecting lost references. You have to fix them manually feature by feature. So the higher up the timeline something is, the less feasible replacing it becomes. It's incredibly frustrating and leads to workarounds where you remove a component and put another one it at the end of the timeline and then just rigid group the whole affair so it doesn't fall apart. Very wrong but that's what one has to do if one wants to quickly swap a part everything else is built on. You then get a bunch of knock-on effects when removed components can't be updated (for some reason that escapes me) and your whole project is constantly flagged as needing a "Get latest", etc, etc.

Been asking for a reference swap doctor for replace components for as long as I know Fusion. Can't be vibe-coded either as the API doesn't let you manipulate references like that.

@Doubletop_ somehow with fasteners it's different. If you use McMaster or other external models - then yes, you'll have to swap them with Replace Component as described above. But if you use Fusion Fasteners you can use right click - Edit Fastener and change the fastener without having to manually fix references. Which just goes to show it can be done if some resource is applied to making it happen. I get it, bolts and nuts are all placed in a similar way. But it shouldn't be rocket science to figure something out for other parts.

I just have a vague recollection of something that worked. Was it in Inventor or an early version of Fusion?
