Mirroring multiple parts in a multi body part and keeping position in assembly

eedmondsHRMXH — Tue, 14 Jan 2025 06:28:28 GMT

In a multibody part, I have these 3 parts highlighted. In the multibody, I mirrored them, but did not create a new solid as I want to mirror them in the assembly to re-use the primary part.

The LHS (highlighted) parts are grounded at origin - so they move and update with the master part. But the mirrored ones are grounded using assembly mirror function, so they do not update position with the multibody part, and I obviously can't ground them at origin because then they'll just be in the same position.

I do not want to delete the mirrored part then re-mirror the LHS parts, as that will probably mess up my drawings and it is a slow workflow.

How do I integrate this exact-same-part-in-a-different-position adaptability in my assembly from a multibody part?

I want to avoid creating new solids for all mirrors etc. - even though when converted to an assembly it will be adaptive. Surely there is a better way.

Consider working on derived parts. They allow you to select bodies, as well as the direction of mirroring for individual cases (files).

Have the Multibody layout part in the assembly, and constrain the additional instances to it.

Hi Kacper,

I'm not really familiar with what you're saying. The parts in my assembly are derived from the master part?

I actually started to try doing this beforehand, but the workflow seemed slow, so I assumed there was another way.

Is this something you do?

Thanks

Yes, this is what I do. My first choice, when possible, is to use feature patterns in the multibody and use an associative component pattern in the assembly to place the multiple instances. When that doesn't apply, I constrain to the multibody. Typically this is three Flush constraints to matching faces on the part and multibody.

"Seems slow" relative to what, exactly? This is already a time-saving method vs. traditional manual constraints. What faster method do you propose?

Hi! The associative mirror component is something we have been working on. Please feel free to sign up Inventor Feedback Community (https://autode.sk/InventorBeta) and take a look at the workflow on the latest internal build.

Many thanks!

Feature patterns is a good idea, I didn't think of this. That will work for some of my parts, however like you said it is sometimes not possible.

I don't have a method yet - that's why I asked the forum.

Thanks for the reply.

That's good to hear!

Thanks
