AutoCAD Inventor :: How To Create A Motion Constraint
Mar 14, 2012
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?

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.

I want to create some universal bricks creations. These bricks have studs which fit into another brick. To constraint them I need to do following actions:
- click place constraint
- Assembly >> Insert >> opposed
- Offset 0,35mm.
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 inv2011. I have to create rec. blocks very often and in inv2011 . I have to constraint it in middle.
Can i write a Macto that gives me constraint rec block in sketch. This feature already available in Inv12.

I'm trying to create a telescopic cylinder motion in Inventor, making the cylinders move together.
Like in this video: [URL]
Is this possible without using inventor studio? I can't figure out what constraint or joint to use.

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).

I have an assembly which has components mated to a radial surface, I need to locate the center of a round slot against an axis, I have X Y coordinates, how can I constrain that part to those X Y coordinates?
Attached is a picture of the assembly.

I am currently creating a chain block to be animated later on. But, I do not know how to constraint it.
I have attached a zip file of the .ipt and .iam

Maybe I've just been doing it wrong for the last 5 years, but the Angle constraint is obnoxiously unpredictable. When I constrain a part in an assembly with an angle constraint from the assembly origin plane (or anything else), Inventor always has two solutions; a positive and negative.
Is there something I'm missing here, or is just a design flaw we have to live with?

To create an animation similar to the one shown in the page 225, in the tutorial, I created a curve but I am not too sure that was the correct way to create it.
1. Selected the Surfaces Menu.
2. In the font view, using the CV Curve Tool, created the first half.
3. Using Duplicate in the Edit Menu, I created the other half.
4. In the Edit Curves Menu, selected Attach Curves and connected two curves.
5. I, then selected the Animation Menu and created an object to be used as an aircraft and followed the same steps shown in the tutorial and it worked nicely.

Usually in the previous versions of maya I used the timewarp in conjunction to motiontrail for retiming my animations. In maya 2012 seems no longer work.
When I apply the motion trail to my object that has changed with timeWarp, the keyframes are displayed by Motiontrail as if there was the timewarp.
In the old motionTrail there was also a chance to see every single frame of animation with a number, not only keyframes.

I'm trying to create and input a motion template for the intro of the interview I shot. Something simple. I've done it before with Motion and Final Cut Pro. Is there any program that would be comparable to motion for Premiere Pro?

I have a question regarding a transitional constraint between a pin and a surface within an adaptive assembly.
I would like the pin and the surface to be transitional only when the two parts "interfere" with each other.
At the moment with the example attached part A is remaining tangent to part B, restricting the necessary movement of part B to function properly in the mechanism.
In simplified terms I need part B to be able to break free of the "transitional constraint" of part A under certain movement conditions within the mechanism.

This is probably a simple one that I am missing, but how do I get a parallel constraint applied to these two edges.

I have noticed what I consider a bug in AI2009. When trying to delete a coincident constraint using the show constraint command, it is impossible to do so. All other constraints I can delete while I am in the "show constraints" dialog box, but not coincident constraints. As soon as I get out of the "Show constraints" command, the yellow dots are still showing and I can then hover over them and they highlight so I can delete them. Is this how it was intended or should I be able to delete them like the others while still in the "show constraints" command?

I'm running 2014. Somehow, in my ignorance, I have managed to turn off the constraint symbols that show up beside the cursor as I'm sketching.

Is there a way to expand the constraint window so that I can see my entire parameter formula? In the image below, my equation is cut off in the "offset" window. Or am I supposed to be inputting the parameters in some other manner?

I'm having a really difficult time maintaining my parameters when making changes to the part I've made in the attachment. The control parameters for this part are:
-100 mm distance between 15mm circles
-1 of the 15 mm holes
-30 mm hole
I am new to inventor but I would also like to be able to set up my constraints correctly. I'm also not sure if my sketches are ideal for this part either. I usually get an error concerning my fillets from the base to the center support beam when I try to change the 100 to 75.

I've assembled a bolt and a slide block that is constrained to a base plate and am able to put everything in motion. I have the slide block constrained to slide the distance of the base plate and when I reach the end the bolt continues to rotate when, if this was a real part, should stop. How can I get this bolt to stop once the slide block reaches its ending constraint?

How do you constrain an object to the origin once the origin constraint has been deleted. I'm not really sure how it became unconstrained in the first place. When I try to constrain the drawing using the coincident constraint it won't allow me to select the origin.

Why can I not constrain placed objects with three constraints? Anything I place constrains with one constraint then is virtually fixed (without being) and cannot even be moved to allow for further constraining.

My need is to assembly parts into an assembly by a known position in the assembly. The part has a UCS and I create UCS on the assembly programatically. What I cannot do is to constrain the two UCS. I tried this (Inventor 2013 x64 on W7/W8 64, c++ 2010 by the way DEBUG mode is not working from the IDE):
CAssemblyComponentDefinition compDef = doc.get_ComponentDefinition();
// MOdules UCS
CUserCoordinateSystems coords = compDef.get_UserCoordinateSystems();
CTransientGeometry geom = m_InventorApp.get_TransientGeometry();
CMatrix matrix = geom.CreateMatrix();
[code]...

Basically, I would like to do this:
[URL]..........
(i.e., take two object Z axes and constraint them to be the same), but in C#. In particular, what puzzles me is that I cannot make
'Get the Z-axis work axis from the occurrent.
Dim oPartAxis As WorkAxis
Set oPartAxis = oPartOcc.Definition.WorkAxes.Item(3)
in C# because the Definition object has not a WorkAxis instance.

See attached screen shot.
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.
