Workflow in this is like guiding a wise blind man, you must be specific and show and tell everything to make it work. Leap over one step and forget to mention about it and all will fail.
Creating arrangements with the same name in the top level and all sub-assys won't make it work alone. When...
To change the old sketches first select "Sketch" to selection filter and then select them all by Ctrl+A. Then right-click on one of the sketches, go to Settings and enable the same option from there. I think this should affect the old ones as well.
With Arrangements I was able to create an assembly where the top level arrangement drives the sub-assembly arrangements as well. From there on the sub-assembly specific arrangement suppresses or unsuppresses the components in the specific sub-assy. Before I explain anything more could you verify...
NutAce: This goes a bit off the topic but you can use Arrangements to drive parts two levels below if you use Position Override option in the parts you are driving with Arrangements.
It depends on the scan quality which way I start building the surfaces. I create several of them too when the quality is too poor to create everything or most at once.
I can share the NX file, note that I've done it with 11.0.1. I share couple pictures of the surface pattern to get the idea...
Suskam have you thought about using Deformable Part for this instead trying to do it with Reference Sets? I think it would be worth considering it as well.
Gunman: did you try to create the whole guitar with only one surface? I did mine by using only one Rapid Surfacing feature as the stl quality seemed to be rather good. Or do you see some advantage on using several of them and then creating surfaces in between?
I gave it a try also as it seems like an interesting project as a whole.
Might be that you don't need it all anymore but it was good practice with the reverse engineering tools while trying to keep the surface quality adequate.
Good luck with the project!
Model...
No there's not an easy way to do that. Only way I can think of doing it is to open the NX 3D model in some program that is able to export .obj files. Then you can import the .obj file back to NX as a subdivision body.
Might work or not, definitely not a supported workflow by any means..
If I try to open the motion_1p.sim NX is trying to locate pushrod2.prt which is the assembly file used in the motion simulation. That should be included in the files too. Same happens with the motion_1p1.sim.
Can you include that file too because else I can't open the simulation.
I don't remember having any problems with the second constraint. Is it possible that you could share the model or at least the necessary objects of it?
