AutoCAD Inventor :: Spring Steel Constraining

Jul 2, 2013

I have a piece of steel that I need to flex. It is a piece of blue tempered spring steel pressed against the corner of a brass pressure transfer. The opposite end of the transfer is tangentlly constrained to a latching mechanism. When the latching mechanism is lifted, the transfer rotates slightly around a screw (made invisible) and the spring is flexed. When the latch is released, the spring returns the latch to the closed position. I have several other assemblies that use the same principal, but some with just a piece of mild steel used as a cover as well as a spring.

AutoCAD Inventor :: How To Make A Spring Moved

Aug 8, 2012

I can't make a spring moving according to other parts' behaviour. I use Inventor 12. by the way I  sent two photos (scanned by Microsoft Security Essentials-no problem), the spring in the photos was made by design accelerators-as compression spring. I want from spring to move with the other parts but it doesn't. For instance when I pull the blue part down, blue part, and the spring go the into of each other.

AutoCAD Inventor :: Drain Care Spring

May 29, 2013

Inventor  offers us several options to design a coil of constant pitch with a tapering diameter.  However, I am unable to create a coil with a taper and a changing pitch at the same time.

We are using Inventor 2013. I would like to produce similar parts as the attached 2D drawings in 3D, only with a changing pitch (distance between revolutions) per revolution.  Can it be done?  There is software for the CNC spring manufacturing machines to produce such parts. Therefore the proper inputs to produce these effectively and efficiently, are available somewhere.

The part I've been describing uses .09 diameter wire and has about 54 coils in about 8 inches. The starting inside diameter is about .53" and the pitch is about .27" the ending inside diameter is .109" +/- .01 with a pitch of about .091".

Here are 2D drawings of similar parts, the last (NF3) is closest to what we need.

AutoCAD Inventor :: Create Coiled Spring On Arc?

Jul 19, 2012

Is there a way to create a Coiled spring of 26 coils on an arc radius of 3.781inchs arc length of spring is 13.706inc

The major dia of the spring is 3/8 inch with the wire dia is NOT given

The original Hand done drawing are attached in PDF version 6 format

As for Inventor I'm using 2012. It is the first time I have come across this sort of problem I thought of doing a single coil and creating a sub assemble of it around a construction line arc rad with each coil mated and rotated at an angle to the other but then thought that there must be  an easier way of creating this spring.

AutoCAD Inventor :: Constraining Assembly To One Motion

Nov 12, 2013

When I rotate the drive shaft gear very slowly, the assembly follows the the correct motion path, (figure 1), however, when I rotate it quickly, the assembly snaps the linkages to an orientation that is not physically possible, but satisfies the geometrical constraints (figure 2).  I can't use contact solver because I am using the adaptive function for my sub-assembly to avoid having to re-constrain many parts.

AutoCAD Inventor :: Tube And Pipe Constraining

May 10, 2013

I'm just getting started using the Tube and Pipe environment for some of my work, and I've got what I'm hoping is a simple question with a simple answer. In the picture attached I've got a 1" pipe dropping down into a 8" pipe which I've disabled because it's a standard part right now and I want to replace it with a tube & pipe run. The thing I seem to have the hardest time doing when routing my pipes is aligning/offsetting my nodes with existing geometry in the assembly. In this case I want the end of the 8" pipe to be 12" offset from the centerline of the 1" pipe, and for the 8" pipe's centerline to be 12" below the bottom of the mezzanine's I-beam (as the standard part it is now). What's the best way to do this in the Tube and Pipe environment?

I tried "Include Geometry" from the "Create" panel but that only lets me create planes, which won't work with offsetting from the 1" centerline. However, SOMETIMES (it's a big sometimes) ALL of the options in the "3D Sketch" tab are available. When that's the case, I can go to the "3D Model" tab and create workpoints, axes, and planes. Sometimes, though, they're not all available, and I'm not able to place anything but planes. How I can change it so I can always use all the geometry of my assembly?

Also I'd like to know if constraing fittings and point-snapping routes to my assembly geometry in this way is the best way to do Tube and Pipe routes. Will doing this allow my routes to update if the assembly changes?

AutoCAD Inventor :: Constraining A Part To A Point

Dec 26, 2012

I am assembling a weldment and need to place a looped bar onto a tubular stanchion 50mm below the top of the stanchion. I have made axis at each point on the stanchion and the bar, but i cant figure out how to constrain the loop to the point I require. All I can get it to do it to constrain to the centre of the stanchion only.

AutoCAD Inventor :: Constraining A Wire Track

Nov 14, 2011

I am having trouble constraining the wire track in the attached picture. I want the track to move naturally when the sliding piece moves, however it folds over on itself and doesn't stay in line. I can't figure out anyway to make it look uniform and move they way it should, is it possible in inventor?

AutoCAD Inventor :: Constraining To A Random Path

Oct 22, 2012

My goal is to let some wheels roll in a path which exist from 2 straight paths and a corner. I can constrain them to 1 path at a time but not to all of them so my wheel makes a corner. I

You can find the guide rail as attachment. There is a path in the sketch from which i sweeped my form but he divides it in the 3 parts so i can't constrain the center point of my wheel to this path.

AutoCAD Inventor :: Constraining A 3D Sketch To A Part

Dec 13, 2011

I am trying to make a 3D sketch that is constrained to two different parts in an assembly.  I want the sketch to be constrained to each of these parts so that if you move the parts relative to each other the sketch will adapt. 

I have tried using work planes and project geometry but when I go to move the part the geometry won't always follow the part.  I am using a spline for the 3D sketch so it should be able to adapt when the parts are moved but the problem is constraining it to something that follows the part.

AutoCAD Inventor :: Show Spring Flexing Back And Forth

Jan 2, 2013

I would like to animate the model so that it moves like a whip antenna.

I would like to show the spring flexing back and forth with everything above the spring moving side to side as spring moves.

I have tried several ways to do this but have not had any luck. I haven't done a lot of animation.

I have attached the assembly and parts.

It doesn't have to perfect it's for a presentation.

AutoCAD Inventor :: Fully Constraining Parts In Assembly?

Apr 11, 2013

I am trying to make a robot chassis in inventor using vex parts. I have a full library of vex parts. I have my basic chassis constrained but for some reason when i use the move command the parts still move, but then snap back into place.

Also, after giving up on the moving chassis i tried to move onto bearing flats. Bearing flats consist of 3 holes in a line that match up with the holes in the chassis rails. I constrain the face of the bearing flat to the face of the chassis rail. This constraint works and removes a degree of freedom. However, when i try to remove the other 2 degrees of freedom they dont seem to go away. I use the tangent constraint, constraining the hole of the bearing flat to the hole of the chassis rail(which is square) using an offset to make the hole centered. I constrain in both of my remaining degrees of freedom, but they bearing flat still moves.

AutoCAD Inventor :: Importing And Constraining Vector Drawing

Apr 10, 2013

I have a vector drawing of a logo, currently in adobe illustrator format. I'd like to create a 2D sketch in Autodesk Inventor and then insert this drawing into the sketch as a shape that can only be placed and scaled.

The way I'd expect this to work is essentially that I'd get a rectangle X enclosing vector object Y, and that I'd then be able to create a fully constrained Inventor sketch by simply constraining the corners of this rectangle X. Is it possible to do something along those lines, and if so what is the best practice for it? 

What I tried, which failed, was this:

1. Converted the AI file to a .DWG file

2. Used the "Insert ACAD" command to place the file in Inventor with the Constrain End Points and Apply geometric constraints boxes checked (other boxes were unchecked)

3. Waited for a surprisingly long time for this operation to complete, maybe 30s on a 16GB 2.6GHz quad machine 

The result of this operation is that I now see my imported geometry, BUT all vectors are treated as individual shapes and I have 2637 dimensions needed.
