How can I model a wire (rope) which acts like thread??

(First, i apology about my poor english. I'm not native)

I want to make a rope using Inventor 2009.

There are V-belts, chains in Inventor.

But what i want to make is a thin rope which is similar to thin thread.

and i couldn't find any information about it.

I expect a rope which have two ends.

So, i will attach a block to one end(of rope) and spring to the other end using constraints.

Then, I will simulate the siatuation which straight up the block

using fixed single pulley by pulling the spring.

But i have no idea how i can make thin rope which acts like a thread.

Is there anyone who can help me??

Thank you for reading.

You can make a thin rope (string/thread) by extruding a very small circle, making it act like a string cannot be done.

I dont quite get what you mean by act like a string/thread /rope?

I just want to make thread like above picture.

which have follwing characteristics.

- No elasticity

- it can endure some force to be not cutted (unlike electric wire)

- can be folded freely

I'm just wondering that how can i configure the physical property of thin rope which can be made by extruding a small circle.

Can i make it act like a thread?

Simple answer is no. In Inventor simulation it has dynamic simulation but I don't think it can do what you want it to do.

Oh.. It's sad news

Anyway, thank you very much for reply.
