Subassembly positions and flexible constraints

407 Views, 4 Replies

I have a sub assembly consisting of several components.  I enabled flexibility to position the subcomponents in the main assembly how I wanted them.  However when i double click or "open" the sub assembly the positions of the components revert back to their original state.


The assembly is a lubrication system, and the reason i need the final positions updated in the original sub assembly is so that i can run hoses in the sub assembly, keeping the hoses out of the BOM for the main assembly.


Any and all help is appreciated (to include "you're doing it wrong")

I think this works...(not sure if tube/pipe routes can be demoted but)

If I were to do it I would place all the parts into the top level sub, add my hoses then select all the parts that should be in the sub, right click and select..component.. "demote". That will move all those parts into their own subassembly..

This might also be a good application for making the subassembly adaptive rather than flexible.  This will only work if this is the only assembly in which this subassembly is used, because an assembly can only be adaptive to one instance.  But the advantage for this application is that the subassembly position is controlled by its constraints in the main assembly.

I appreciate the help guys.  With minimal experience in inventor (~6 months) any and all help/suggestions are accepted.  I'm still in the portion of my learning curve where im figuring out how to optimize my modeling methods.  Both recommendations have been filed away in my mental storage for use on future projects.

Little complaint on this issue.... when you take an assembly that was used adaptively in a larger assembly, and do a copy design on it so it can be used differently in a new larger assembly... shouldn't Inventor automatically clear the adaptivity on the copied version?


 For the life of me I could not figure out why I was unable to set this new, copied pump assembly as adaptive on my skid.  Then I read this post, and remembered a little obscure trick someone once showed me.  Went into Document Settings (of all places) and unchecked the "Used Adaptively..." box, and everything was fine.  How in blazes is anyone supposed to know about this, if they haven't already seen it done?!  I think that a copied sub-assembly should automatically be cleared, or there should be a right click option to clear adaptivity on parts, rather than having to dig through Document Settings looking for a tiny check box that most people probably don't even know is there.


I love my job, I love my job.....
