Patterning a seed component that is already part of another pattern

Hi,

in feature patterns you can pattern a feature, like this hole:

You can then select the same seed feature to create another pattern:

The same doesn't seem to be possible in assembly rectagular patterns.

I have inserted the plate into an assembly:

I pattern it a first time:

I would then like to pattern seed component a second time, but it doesn't allow me to, it obliges me to pattern all components:

I think the source of the issue (not being able to pattern seed component a second time) is that seed component has been absorbed in the first pattern, and you're not allowed to make it indipendent from the pattern.

In attach is my sample assembly.

Is this a limitaton and what would be the best workaround ?

Thanks,

I didn't open the assembly - but what attaches to these plates?

Maybe a better/faster solution would be to have feature pattern in a mating part and then simply place the plates in the assembly via the mating part feature pattern.

Hi Alex,

There are two ways to solve the problem. Like JD indicated, you could use feature pattern driven component pattern. Basically, create a feature pattern of a feature or a workpoint in a part in the way you want the component to be pattern. Then in the assembly, select the feature pattern as the guide and select the component you want to pattern.

The other way is to make the pattern components independent. Simply right-click on the pattern occurrence in the browser -> Independent. Once you do that, the occurrence is no longer part of the original pattern.

Many thanks!

Thank you for your replies.

I guess the best solution is Jeffrey's.

I can't exclude from the pattern seed component, and moreover by excluding it is unconstrained.

I find it weird that there's not consistency between feature pattern behaviour and component pattern behaviour.

In Fusion 360 behaviour is consistent, since I can create a second pattern and choose seed component.

This is such annoying behavior. Why not to fix it?
You cannot make original component independent in its original location.
Only second (or consecutive) element can be independent. The logic is completely illogical.
What also happening is that independent component becomes independent from the pattern, meaning pattern is missing component.
If you remove independent check mark, it becomes a copy in place... Guys, how you come up with this??

The problem is that, if I want to make pattern of same component in 2 opposite directions, there is no way how to make that without additional "workarounds".
Pattern itself designed such that, is does not consider parent component as independent after first direction selection. And if you do second selection in opposite direction, pattern automatically includes all seeds in first direction selection .... So annoying guys... 2025 and no improvement.
