Flexible Assemblies
Flexible Assemblies
(OP)
Anyone who has seen NX's tractor demo has seen them grab a hold of the bucket and move it around. When they do this the hydraulic cylinders extend and contract. As simple as this seems to me, I can't figure out how to make this work. In SolidWorks you just didn't constrain the length of the cylinder and made it a flexible component in the assembly. Someone please tell me it's that easy in NX and I'm just missing something. I'm currently using NX6.

Note that the cylinder on the left has NOT been modified so if you attempt to move its piston sub-assembly you will see that it's not selectable as a movable object at this level of the assembly.
Now to show you how easy it is to override the positioning of this piston sub-assembly, for the cylinder on the left, expand that assembly in the Part Navigator so that you can see the piston sub-assembly (you do not need to expand it). Now select the 'piston_assy' component, press MB3 and select the 'Override Position' item from the list of options, which you will find in the second group of items with a Green UP Arrow as it's icon. Once the system returns control to you, you will find that you can now use the Move Component function to move the piston sub-assembly in the cylinder on the left just like you were able to do with the piston in the cylinder on the right.
Now to remove the override, just reselect the piston sub-assembly, press MB3 and select the item which is now labeled 'Remove Position Override' and you will be back to where you started.
Note that you can perform this operation at the top-level assembly without actually needing 'write' access to the cylinder or piston assembly files since all the changes are made in the top-level assembly file.
Also note that the attached cylinder assembly can be opened and manipulated as described in NX 5.0 and as well as later releases.

RE: Flexible Assemblies
Thanks for posting the example I'm pretty sure it is the same one that helped me to learn about this when you posted it once before. Searching the forum for some reason is only giving me results starting at 2007. I wish I could have saved you the trouble of typing out the explanation all over again. I knew there was something more to it that I hesitated to explain because frankly although the method is really great unless you're a big user of cylinders you tend to come back to it only sporadically.

Deformable spring attached. Add it to an assembly and use the slider to determine a length.

RE: Flexible Assemblies
Thanks for your response. I was a little suprised that no one had asked this question before. I guess I'm not the only one having issues with searching the forum.
