Construction of a curve with a controlled length

Ahorrar,
I think this is not going to be possible.
You specification is TOO general.
Let say your controlling length was say 100mm.
You could make a change to a point which would render no solution as it may be impossible to keep L=100mm.
Can you explain your reasoning for doing this as there maybe another way around it?
Regards
Nev

Thank you for answer Nev,
I need to route a flexible cable under two trorque-arms of a landing gear. There will be 2 fixed points on each torque arm (upper and lower) and then the spline between them. The upper has a pivot on the cylinder and the lower one has a pivot on the piston. Both stares one end, the apex. The flexible will go over this apex.
The angle between them is variable during the landing and takeoff and I need to simulate this flexible cable.
I did it in ProENGINEER in the past, but now the project I work is in CATIA. I thought I can do it, but seems to be difficult or even impossible only with the basic licenses.
Thank you again,

Hora,
I would say that it is possible. You need to sort of mimic BMX (Behavorial Modelling) in ProEngineer. You will need to iterate through the various tangent angles and tangent tensions for your spline until you reach the target length versus the current length based on the modification to one of the spline end points.
It will require some nifty coding to do it but it is not impossible.
I can email you a Vr15 part to give you an idea how to craet the start part.
Also note CATIA has a BMX equivalent called PEO(Product Engineering Optimizer) you should be able to do it with PEO without the need for coding.

Neville
