Hole propagation in a pattern

micromelt01 — Mon, 06 Apr 2020 15:05:15 GMT

Hi,

I have a group of jointed components. I create a hole on the middle component and attempt to apply a pattern across all of the components that share a plane. The holes only propagate across the middle component and not the adjacent ones. I am working with the top level activated.

Any suggestions welcomed.

This is a current limitation of all the feature/face pattern commands - they only work if the target is a single body, so you cannot pattern holes across multiple components or even bodies within the same component.

Thanks for the info.

I hope this feature is on your 'things to do' list.

regards,

Hi Jeff

I have read your explanation again and I must admit to not fully understanding.

I created a hole which went through one component and two attached bodies and then also through another component and 2 attached bodies; 6 bodies in all. Then I propagated the hole and it was copied through all 6 bodies in 4 positions so I have, it seems to me, patterned holes across multiple components and bodies within the same component.

So it appears to work on components 'further away' but not 'next door'.

regards,

David

good question. Understand why this may be confusing. The short answer is: Hole supports cross-body/cross-component targets, but Pattern does not. You can see this in the screencast below.

The reasons why are internal and a bit complex. When you create a Hole through 3 components, there are actually 3 Hole features created behind the scenes - one for each component. These are all represented in the Timeline as a single Hole feature, but there are actually 3 of them. This is mainly done so you can do Save Copy As on a component, and bring all its features along. When you do a pattern of that Hole, we are replicating all 3 features. But, as you see in the screencast below, that pattern will not propagate to components or bodies that were not part of the original Hole.
