Hey, this video was very useful! I've even experimented a bit, and discovered that instead of drilling a hole on the ground, you could use a *work point*, and drive it along the path as well. I've discovered this after trying to make a complex rotation-translation motion along a curved surface, where a drilled hole driving along the curved-surface path didn't behave as one would hope.

He's so good at what he does.

I just have to accept the fact that with Inventor you can do animation, but with smoke and mirror kind of skills. Thank you!

You saved me! Great work, great material, great presentation! Thank you

So informative, thanks a lot!

Very good. Thanks. Jim

Its been a while since I modeled that. I believe I patterned the rail along the path.

I have been playing around with this and I have managed to get a single work point to drive several components along a path "towing" them, but you are correct in that Inventor gets a bit glitchy when handling the constraints under certain conditions: Moving too fast, pushing not pulling, rads too tight. Should be fine for the four items moving along that track though. It didn't work for what I wanted but it was good to learn new tricks. What I really wanted to simulate was a segmented sheet of thin material being driven off a reel. Perhaps there is a different trick I could use for that?

This is very enlightening, Thanks

collll .thanks. it was very useful.

Hi, Once I try to use the transitional constraint to constrain the 'work cylinder' to the path, it doesn't use the whole path. It only uses one section of it (either one of the parts of a circle, or a straight section, wherever I click) and once I've constrained it to that section, the train is unable to move off it, though it can move around on it. I've tried moving my mouse all over the rail to make sure that i'm not just missing the part to click on. I can't quite see what you did in the video because you've zoomed in. Any ideas?

merci beaucoup a toi :))

I am assuming that this is the same concept used for getting an object to move along a conveyor...right.

Great example

Thanks Rusty, I never tried that feature before. Also, how did you created the wooden tracks. Did you do it as an assembly? Thanks

How would you get the object to go forwards then backwards? Trying to do it but can't figure it out.

Hello sir rusty, why is 30s y not 45, 50, 60? i tried to extend the duration to 60s and it's not accepting it.

i love how u blur ur search history

thank you so much

When you set up the animation parameter you got a "timeline over lap" error I am getting that same error but just canceling out is not working. How do you get around that?

Hi Rusty. Is it possible to constrain a box with two fixing points to a 3D path so it moves parallel to the track? I've used this feature many times recently much to the delight of the sales team. Thank you.

Great job

How can I select a whole path, when i tried to make the same path and make a rectangular pattern, it only selected a line segment, not the whole path. Some help would be greatly appreciated.

Is it possible to do something like this in Dynamic simulation? and have some trace points in Output Grapher?

Hi Rusty, How did you create the center Plane profile on the Base Path Sample? Thanks

Can you constrain the wheels to the track in such a way that they rotate as the train moves along the track?

Exellent..!

Wheels are not turning ;)

I am in a bit of a dilemma. I'm trying to use this technique to drive my custom car along a figure eight track that goes above itself and then under sort of like an overpass but infinite so it keeps going around. I constrained my car to the work point but it does not go up and down the ramp like I want it to. Instead it follows the figure eight path at the same level it started from so at some points it is floating. Please give me some tips on how to fix this any help would be very much appreciated.

hey-- how did you create those round workplanes ? thankyou

I don't believe so. The Inventor Studio Environment is the only place you can drive a parameter.

@RustyBelcher I'm trying to get a train engine to move on the track and everything was working fine up until I had to do the animation in the assembly. once I entered all the info for animating the parameter, it gives me the message: "The specified value could not be applied. Please enter a different value" ive tried changing all the values but I get the same value. do you know how to fix this.

how i can drive two parts in inventor without a bath ??

iS THERE A WAY TO MAKE THE WHEELS MOVE WHILE THE OBJECTS MOVES ALONG THE PATH?

How do you make the path?

Extrude the path as a surface.

DOE's any one one here who can help me to give motion to my rotation i part on a path path is circular and straight i want to know about that parameter you giving how can i create that parameter

Sorry, for yourself asking the video movement of water in the Inventor software, who knows only with, you thanks

Edward I believe so. You might have to send two "dummy" parts down the rails and constrain the box to each of those. There should be a couple of ways to make this work. I did a video about a box going down a spiral conveyor a while ago. I believe I used a process similar to the animated sweep video I posted a few weeks ago. Just a thought. kzfaq.info/get/bejne/ntaqd5aY2daaZ6M.html
