stent modeling

[quanvity]

Hi guys, I'm trying to model a stent (it's a medical device) and run pro/mechanica on it. I have done some research and seemed like most of you would use toroidal bend for this purpose.


But here is the question: I don't need the first bend (profile sketch bend) since the stent is a straight cylindrical tube, what can I do to avoid this option?


by the way, does anyone have a stent model (pro/e file) you could share with? I'd greatly appreciate it.

We tried a variety of techniques to model a stent but we
ended up going with a Flatten Quilt / Bend Solid
approach. For some geometries (sorry I know this is
vague) this is the only approach that correctly "bends"
the features (as opposed to a toroidal bend or
projecting a curve onto a revolved surface).

I think we might have a generic model that I could post.
Which version of Pro/E are you using?

Hi Ryan, thanks a lot for the help. I have the Pro/E 4.0 educational version.

I didn't have one ready but I threw the attached together. Hopefully it gives you an idea of how you could
model a stent (there are certainly others too).

I didn't model additional more than one axial pattern, but if I was going to I'd probably model it in the
Flattened Quilt (before the Bend Solid) so I wouldn't have more than one pattern type after the Bend Solid.
