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 am working on a design at the moment using Inventor 2012.It is a Scissor Jack. It has been designed to specific dimensions.Although I am making up the majority of them as I go along.Dim's spec's of which I must design to are as follows,
Max Height @ Open position = 250mm. (must be kept)
Min Height @ Closed position = 70mm. (must be kept)
Max width = 75mm. (must be kept)
The rest I have been taking from other designs of which I saw during my investigation.I have been modelling in such a way trying to adapt the open & closed position limitations with the use of constraints as my maximum & minimum limits. In doing so I have set a Drive Constraint so I can show the jack in its mechanical motion. I don't mind making any changes that will work to achieve completing it to act as it should. I believe there is still some tweaking to be done to it, but I feel the actual engineering design to be almost sound. There is an issue with the base via support arms. I cannot have the support arms moving past the floor level.
I will need to place location pins through the saddle & base connecting the arms. Finally If possible alter the gear teeth so that they interlink & coincide with each other. My screw rod also needs to work properly & turn also the nut needs to be localised in the correct position fixed on the screw rod at the end of the Side sleeve.
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.

PS... if you go to this youtube video you can see what im trying to do: [URL].......
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).

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?
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.
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.
Is it possible to make a Lisp program to move a mechanism by a dimensional constraint?
View 9 Replies View RelatedI'm trying to make a view showing a motor-jackscrew unit with the jackscrew at the fully retracted position and also with the jackscrew at the fully extended position (in phantom). Refer to the attachment.
My initial plan was to have two views in the drawing, one retracted and one extended, and then just align them vertically and horizontally. But it turns out that you can only align vertically OR horizontally, not both at the same time. So I created an assembly of two iAssemblies, one with the screw extended and one retracted. Then I made the drawing view from the direction that placed the extended assembly directly behind the retracted assembly.
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?
I'm basically looking for the different fonts to use, etc. to make my label look fairly authentic, but I'm having a hard time finding the correct ones.

View 4 Replies View RelatedI 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.
View 4 Replies View RelatedI 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?

View 9 Replies View RelatedI'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.
How do you delete a constraint between a point and the center point of a line? (in the sketch environment)

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?

View 9 Replies View RelatedMy 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();

Basically, I would like to do this:

(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.
We have an interesting problem after reinstalling the software. We found that there is a time lag between the mouse pointer and the line highlight to indicate we have click the correct entity. The video attached in the link below may be able to explain our problem better. In the video, we move the mouse to where we want it and it shows a time lag.

I can't seem to get inventor to select a given parameter inside a sketch. It keeps giving me an error.
All I want to do is to have inventor Select / Highlight a parameter inside of a sketch so the user can clearly see it in the window. Ive tried heaps of different selection options, I just can't work out what ive done wrong.
