Im working on a miniature train project of PLTW... I have completed the train and made a track for it... but i can't figure out how to create a drive/motion constraint that would make it go along the track.
(All the files are in a zip folder that is attached)
PS... if you go to this youtube video you can see what im trying to do: [URL].......
I have a Scissor Jack Assembly in its open Position. (fully constrained)
I would like to be able to use Drive constraint & show the Assembly in its closed position.
I know I need to adjust one or two of my constraints.
Attached is an assembly that I created. It includes a timing belt, 2 pulleys, 2 shafts, and some profile lugs that are attached to the belt with a false tooth.
1. why can't I constrain the profile lugs around the radius of the belt? Also, when I created the belt and put the holes in it, they disappeared because they ended up in the radius of the belt.
2. Is it possible to create a motion constraint to this model, so that it moves like a real belt?
I am designing a vertical axis wind turbine just for some practice (just started using Inventor) and everything was going smoothly until I tried to "animate" it spinning. First, I set up a work plane that goes through the center of the structure, and then I clicked angle constraint "explicit reference vector." After watching several youtube videos, I figured that I should click on the work plane, click on another reference point, and then click another point that would be orthogonal to those two (right?). Well after I choose the first point, Inventor will only allow me to choose the center axis as the second option (which I think should be the third option).

To activate the new position of the assembly of approx 5k instances takes about 5 minutes in IV 2013 when using Drive constraint. The larger the assembly the longer it takes
In IV2011 takes about 10 seconds. I've never seen the "Not responding" sign in Drive constraint window in previous versions. I'm just wondering how can avoid this "New feature" of 2013.
I have a video clip of a train moving across the tracks. The camera also pans to follow the path of the train. I want text to sit on the top of the first car of the train as its travels from left to right.
I used Track Camera and then parented text to the Null object.
The problem is that the text has to adjust in size and perspective as the train moves along.
I have tried keyframing these options but the result appears jittery and jumpy as if the text is dancing on top of the train.
The text should be the exact width of the first train.
Tiny in the distance and then large as it approaches cameras.
Also, there appears to be a bug with the text object not displaying the font correctly. I have tried many fonts and each appears inconsistent. I have attached a screen grab.
The red text is how the characters should appear given my font choice. The red is NOT tied to the null object; its just a text layer. The black font is tied to the null object. You can obserce that certain characters are bold and others not. Overall this looks nothing like the font is supposed to appear.
Please note that both titles are the same font. password for the vimeo clip is : train-tracker
I wonder if one can use drive constraint in sketch mode for blocks as I like to visualise how the links move when one dimension changes.

-The codec you selected to compress this AVI video stream cannot handle the current screen color depth and/or the graphics frame size. Please try another codec.
-Then I press OK and it records but the AVI file is empty and no video is watchable.
What can I do?
I'm using Autodesk Inventor 2012 ans a windows 7 64bit brand new computer with Nvidia graphic card.
I am using these set limits within a drive constraint so
to show the Jack opening & closing.
Although it can now open & close with ease,
how I can make the crank turn with the screw rod at the same time as the scissor car jack opens & closes.

- click place constraint
- Assembly >> Insert >> opposed

I would like to make above into 1 action, so just click to add this action, then select the 2 faces to constrain.

I am using CS and the “blend” tool to create a train track but I cannot seem to get the spacing to look right. I tried adding a 3rd railroad tie in the middle but that didn’t work either. How I can get more spacing in the foreground and less in the distance?
View 8 Replies View RelatedI have a basic train that I am doing for a project at school. I am doing a fairly advanced extension of this project for some extra credit and I am wishing to make this train be animated.
Since my first name is Jackson, I decided early on to make a track design in the shape of a J (bubble letter). In my class, the only requirement was to make the train go in a straight line.
What I have now: I have two assemblies of both a train, and one of my track design. My thoughts on how to do this. I thought it would be possible to make the train follow a path or something to that effect.
I have been trying to make a train that i made roll on a track. I have seen youtube videos of people who have made their train go around a track (I have the same dimensions as the people in the video through project lead the way).
I have the train constrained to the track with a tangent constraint. How to make the wheels turn on the track (i know how to make the wheels turn, i just do not know how to make all the wheels turn in unison/together and how to make them actually move along the track instead of make the wheels turn in place.
Here is a picture
I have tried in vain to construct a planetary gear train in Inventor 2011 & the spur gear generator hasn't work much since the results are far from good, I have problems getting all the gears to fit together. The Internal gear has a diametrical pitch of d=120mm & the smallest gear a diametrical pitch of d=20mm, the outcome should produce a 6:1 gear ratio. The 3 other gears only offer stabillity, but I still need to know how I get it all to fit together with my measurements?

Having issues on a laptop with Inventor 2012. Inventor will let the user create a new project folder on the C drive but not on their personal network drive. The user does have all needed permissions to use their network space, but Inventor is not allowing a project folder to be created on on the networked drive.
We have desktops on which project folders can be successfully created on the network drive. Only the laptop seems to be affected by the issue.
Am I missing a simple check box somewhere in Inventor?
Picture this, a tubular feature that has a path that runs along the circumference and turns linnear. A path thats .3125 in diameter. I attached a file that shows a hand sketch with this post but I can't tell if it will show up.

View 0 Replies View RelatedI've built a project up with several smaller project file components. It's an easier way to create a video than editing one big project.
Opening the overall project and running it on screen is not a problem. However, when I try to create a smart package of the composite project, I get a consistent error message rejecting the process because of the existence of the component vsp's.
Is there a way to avoid the error and create a smart package from a project file that has smaller component project files?

View 2 Replies View RelatedI have Smoke (same version) running on two seperate Macs. Each Mac has an external thunderbolt drive for the media storage.
I worked on my project at home on Mac #1, and assumed I could bring in my external drive and use it with Mac #2.
When I try to add my drive from home to Mac #2, it creates ManagedFolder1. Which of course doesn't have my project in it- my project is on ManagedFolder0.
I suppose this may be caused by the fact I already have a ManagedFolder0 on a different external drive for this Mac, right? So I removed that drive, assuming I could then re-add the drive from home and allow access to the 2nd ManagedFolder0 with my project.
It just shows my old projects from the other drive still, but everything is broken inside of them. This makes sense as the drive is disconnected.
