autodrop with "insert multiple" highlighted stacks all screws in original hole

[mmwhite8AXBE]

when trying to place a flat head socket screw into a mating hole using autodrop content center places all screws (3 screws in this instance) in the original hole. The software seems to see the other applicable holes as they are highlighted (see autodrop 1). It also seems that the iMates are all tied to the original hole (see autodrop 2). I  have also included the sketch used to create the holes.

Any help is appreciated,

Mike

Hi

Please try selecting a different hole or attaching a file.

hi,

I tried using the other holes with the same result. I found that this sub assembly had 5 or 6 failed constraints in an unrelated area of the design. Once all of these were fixed or deleted (even one failed constraint caused the problem to reoccur) I was able to place the screws with autodrop and insert multiple. Why would an unrelated failed constraint cause this feature to fail? Is there a work around for this?

Also the proprietary nature of this assembly makes it difficult to send.

thanks,

Mike

Oh, that's clear.

You shouldn't stop working on a sketch until it's fully constrainted.

Hi! The behavior does not sound right to me. If possible, please share the files in zip with me directly at johnson.shiue@autodesk.com. I would like to understand the Auto Drop behavior better.

Many thanks!

Hi @johnsonshiue! I'm able to reproduce this behavior on any assembly file. If there's a sick relationship anywhere within the assembly, the autodrop will stack all screws in the same hole (using Inventor 2024.3.4).

Hi! When there are failed constraints, it is better to fix them or delete them. Keeping the failed constraints may incur performance penalty, because Inventor Assembly Constraint solver will try to resolve the failed constraints. Go to Tools -> App Options -> Assembly -> check "Enable redundant relationship analysis." Does it work better now?

Many thanks!
