Help on designing Nitinol stent in SolidWorks

Help on designing Nitinol stent in SolidWorks

(OP)
Hi,
   I need to design a Nitinol stent in Solid works software. I have the initial laser cutting dimensions. I am able to draw them in the 3D. I want to know if we can expand that initial tubing and get the final 3D model of required diameter. Please let me know if anybody know about how i can change the Nitinol tubing from 5mm OD to 25mm OD?
   Thank you.

Use a Loft or Sweep. Guide curves may also be needed depending on the finished shape required.

cheers

Hi
  Thank you for your reply.  I used scale command, but it doesn't give me required results. In reality i have to heat treat the small diameter( say 5mm) nitinol tube and expand that to required final diameter( say  25mm). Sacling up command scale up all dimensions, which doesn't happen in real experiment. Some dimension increases and other dimensions decreases. And I don't have the proper correlation between the changes happen during expansion. Is there any way i can creat 3D model of the initial frame and using some command see the final 3D model.
  Thank you.

I don't know how you have your model set up, but from image searching "Nitinol stent", this looks like something that could be done with Design Table & Configurations.

Are you trying to deform the stent?  If so FEA would be more appropriate.  Hope this helps.

If you're doing what I think you are, which is attempting to model the physical deformation of the Nitinol with regard to the temperature change - no, Solidworks (or any other parametric modeler) will not model this.  You can use configurations if you want to see both the deformed and un-deformed state, but you will have to model both configurations manually.

You could attempt to mimic this using an assembly, like an arrangement of pinned joints and struts - otherwise you're asking for a sort of morphing or deformation command, by its nature engineering software is not good at this.  

You could try a 3d graphics program like 3d Studio Max or Lightwave - they have deformation tools that can mimic this behavior.
