iMates not working ...Why?

[Anonymous]

Hi,

In our content center we have a stud that we use often, it has iMates built into it but they don't work. I'm trying to fix this because unlike other fasteners that we can auto drop this one is causing more grief.

I will attach a sample file I hope they are usable. You can also see that I'm exploring what is the best way to constrain those studs. If you have any input to share it would be great.

Thanks,

Hi Josy,

Inventor assembly .iam file is not enough to the show the issue. Could you do a Pack&Go to include all the part and subassembly files?

Many thanks!

Sorry,

Here it is.

Hi Josy,

I took a look at the assembly but I still need a little more information on what you are trying to do. In Assembly2.iam, Part3 does not have any iMates, while the bolt has two iMates. Are you trying to mate the bolt to the plate?

Many thanks!

Hello Johnson,

To my knowledge content center components with imates behave differently and don't need corresponding imates in mating part for proper placement unlike parts with imates outside of content center. Normally when we place a fastener from CC we are prompted to select mating faces and they auto drop perfectly constrained.

U0038 is one of those content center component and should behave like all other fasteners but it doesn't for some reason. Part3 does not have any imates and it should remain that way too. For example when we place other CC screws the receiving part never has imates on each holes only the screw does and we have no issues.

It is has if that particular component was not published correctly, it does not recognize faces, features or sketches. Up to now we place a few U0038 occurrences freely in space then constrain ourselves and finally pattern as needed but this is a long and repetitive process that should not be.

Hi! I think I know what you are trying to do. You would like to use Autodrop workflow on a CC part from custom CC library, right? If yes, there is a known issue documented in Autodesk Knowledge Network. It looks like a limitation or a bug. There is no solution yet unfortunately.

Many thanks!

Hi!

I can only guess this is a fully custom part since I don't have access to Inventor default CC library to validate. I am not the one managing CC but know that our custom fasteners are created using the default Ansi or ISO families included in Inventor. That could explain why most of our custom fasteners imates work at placement being derivatives of existing components. Maybe in this scenario U0038 was completely invented by us, I don't know. But would that explain why it does not mates properly even on single placement without auto-drop?

Thanks again for your input.
