Sharing lip dimensions across parts

[nwk23]

I want to make a 1:1 3d print of an assembly but its too big for any available printers.  So I shrinkwrapped the assembly, did Save As Part A, and extruded away 2/3's of the model.  Went back to the shrinkwrap, Save As Part B, extruded away different parts of the model.  Lather, rinse, repeat until I have the model in 3 pieces that will fit in the print volume. 

Then I used the Plastic Parts Lip command to create alignment features on the relevant faces. I went with an .08" lip because I'm printing at low resolution and I want a chunky surface I can glue up, but that looks like its creating a defect in the assembly.  

Is there any way to set things up so I can change one value and have the lip, and corresponding groove width change in all three parts?

B and C Files are missing from your attachment?

I suspect that I would have used Split rather than whatever your technique was.

I think there is also a utility built in for this process, but I have never used it before.

I could only attach 3 files, but I'll look into Split.  If you open up Part A, you'll see I just did an Extrude-Remove to get rid of parts of the model. 

As to the utility, any clues to its name?

Do you have to do the low resolution?  I personally would think it would be better to go to a higher resolution and alleviate this problem.

Oh, as a side note, yes you can only attach 3 per posting.  You have two postings.  Attach the balance to the second posting.

Place all relevant files into a folder. (I generally already have this project folder.)

Right click on the folder and select Send to Compressed (zipped) Folder.

Attach the resulting *.zip file here.

Yes..

There is also the Lip tool.

So many ways...

Hi! The easiest way to pass parameters among components within an assembly is using an iLogic rule. Create an iLogic rule in the assembly. You can access any parameter within any part in the assembly. Just use an equation to equate the two.

Another way is to link one part to another. For example, you have PartA and PartB. You would like to link PartA's parameter to PartB. Open PartB and go to Parameters table -> Link -> pick PartA -> select the parameter to link. Or, you can use Derive command in PartB and select PartA. It is pretty much the same workflow.

Many thanks!
