Adaptive Cables, Tubes, and Ropes in Inventor | Autodesk Virtual Academy

Welcome: 00:00 - 1:54
Topic Intro: 1:54 - 3:50
Demo/Q&A: 3:50 - End
In this session, we learn to take advantage of Inventor’s adaptive modeling capabilities to create cables, tubes, and ropes that dynamically change shape and length as their connection points are adjusted. We learn:
-How to use adaptivity in a 3D sweep
-How to choose the right constraints to control the sweep
-Strategies for working with spline curves in a 3D environment
If you have ever needed to model a dynamic, flexible tube or cable, or if you want to learn the techniques for creating an adaptive 3D sweep, make sure to join us!

Thanks so much, was looking for around 2 hours until I found this video

[@joaovitorrebello5818]

Great work! Thank you for your help!

[@JoelyRoley]

What a great demo! I can't believe as a student I have access to such powerful software

[@tomaszkolasinski5810]

It has a simple explanation - if you learn it at school is more likely you'll buy it in your professional career ;)

[@irakperez]

Time well spent viewing this one!

Happy to hear! KETIV | Marco

Just stumbled across this video and watched it to see how closely it compares to the method of modeling hoses that we developed at my company years ago. Turns out that it is very similar. One thing we had struggled with was how to deal with routing through hose clamps. I believe the method you show in your electrical cable example will solve the problems we had. We had been trying to do it using some method with adaptive work points, and the adaptive updating is inconsistent on a good day. I did want to point out that the answer given about controlling the spline length is not quite correct. That is possible outside of Tube & Pipe. However, it was a fairly new feature at the time that the video was recorded, so the presenter may not have been aware of it. He was unable to find it because he was looking in the location where the option exists in Tube & Pipe. Instead, all he needed to do was put a dimension on the spline in the 3D sketch.

Great demonstration. Question: Would this technique work in a situation where one of the components is connected to the rest of the assembly via a slider joint, while the second component is stationary?

Now with this is there any way for inventor to calculate the force required to pull an object through a pulley system as shown?

[@KETIVTechnologies]

Inventor has some built-in design calculators that are intended for very specific scenarios, but cable tension through a pulley system is not one of those scenarios. So, Inventor won't be able to give you this information about your design. KETIV | Cameron Whetten

[@gabrielh5105]

Thanks for this great tutorial. But for some reason, I can't move my parts after I've created the curve. They appear fixed, even though I don't have a ground constrain. Any ideas on why is that?

[@ng3027]

I have the same issue, my parts are now in a fixed position, not sure why

[@TheCapsLock7]

At the example with the pulley, the length of the rope it's not remaining the same when you move the pulley, I am trying to find a way to solve this, but the sketch has too much dimensions if I try to give this a standard lenght so it always break and the sweep becomes red

[@derrickpiche1119]

I'm too scared to do sweeps and cables. But I have a free work period today. I design radial gates.

[@luiitatre]

Why adaptive sketch doesn't work with position representation??

[@KETIVTechnologies]

Thanks for your question. This is simply the way positional representations work. The Inventor documentation specifically mentions that "adaptivity is deferred" and that "results are not pushed down" to adaptive components. KETIV | Cameron Whetten

@@KETIVTechnologies thankyou thousand, you are awesome

[@luiitatre]

@@KETIVTechnologies how can I follow your webinar from Italy?

[@nielsgoris3026]

Fix download

[@KETIVTechnologies]

Guys, appreciate the video, but you need to work on the steadiness of volume. Your voices routinely faded in and out.
