Dear All,
hopefully somebody can help me to find a solution for my folowing issue 
At the moment my company using assemblies for flexible hoses (1 fitting + tube in the middle + 1 fitting) as deformable parts, having lines and bridge curves in the top assy level as a guide for the deformable tube.
When I insert this pipe assy in the main assy I add a constrain for 1 fitting and make the other fitting 'flexible' then I can constrain it where it needs to go, then select the bridge curve as a guise rail.
This method is not adaptive, so if I have to move the position of the fittings, I need to re attach the lines for the guide rail.
With this method I can have the same 'part nr' for many difffeent lookign flexible pipe (but with similar length) , and also I can produce a drawing, showing the original sub assy, with straight tube, so we can source it out from a supplier.
I have now a trial licence for the mechanical routing as the management is looking for a quicker way to do the piping
assemblies.
Is there any way I can achive the same principle for my pipe routes, such as:
-having only one assembly for the similar (same) length pipes, but using different guides (splines) in the main assy,
-have a drawing showing the straight pipe for manufacturing purposes.
I am using NX 11.0.1.11
thanks a lot,
regards,
Richard
