AutoCAD Inventor :: Multi-link Car Suspension Assembly Drawing - Rotational Joints Binding

Nov 28, 2013

I've been teaching myself inventor over the past couple of months so I can design the rear suspension setup for my car.

I've got the IRS modelled with enough detail to show my engineer the concept, but I want the suspension to "work", ie each link will move as the suspension flexes.

I'm attaching the arms (blue, dark green, red and yellow) to the cradle (orange) using the joint command, and selecting "rotational".  This works fine and the arms can swivel about a single axis as they should.  But as soon as I attach the knuckle (lime green) to the other end of all the arms using the same type of joint (except the joint with the blue lower control arm, which is a ball joint), nothing will move. 

I understand that in real life, each joint has a bit of "slop" in it, allowed by rubber bushings, which prevents the whole setup from binding.

To my uneducated mind, the solution would lie in one of 3 methods: Convert all the joints to ball joints (I'd like to avoid this if possible) Add some kind of flexible rubber bushing to all of the joints (probably not possible) Get rid of the rotational joint constraints altogether and somehow mate all the parts to each other using work points, rather than a cylindrical bolt and eyelet, so that each arm has full range of movement in both the X and Y axes.

AutoCAD Inventor :: Why Access To Content Center Available In Assembly Environment

May 7, 2013

Why is access to the Content Center only available in the Assembly Environment?

Surely I can't be the only one that could benefit from access to the library when creating a single tube or beam or angle bracket etc..in the part environment.

AutoCAD Inventor :: Constraining A Part To A Sketch Point In The Assembly Environment

Aug 7, 2012

Unfortunately, it's chock full of proprietary customer data, so I can't share the parts or the assembly.  But I can pretty well explain what needs to happen, and I've attached a JPG that shows a bit of what I'm doing.

I need to design a bracket to hold an RPM sensor at a certain gap to a spiral bevel gear.  I've got a huge assembly model (non-Inventor) from the customer, as well as the model for the sensor.  My plan is to start a master IAM, insert the customer assembly, insert the sensor and constrain him, and draw the various hardware I need around the sensor.

So I start by making a work plane that matches the bevel angle and is in a location so the end of my sensor will be flush to that plane.  Create a sketch on that plane, then project 2 relevant axes to create the appropriate "origin" from which my location will be based.  Place a point on one line, at a certain radial distance and constrain my point.

So now I've got a point and a plane that are where I want my sensing face and my centerline axis to be.  What now?  I was thinking that I'd create a work axis "normal to plane through a point", but this workflow isn't available in the assembly environment.  I can't constrain a solid to a sketch point, so I really don't know what to do at this point in order to put the part where I need it.

AutoCAD Inventor :: Change Appearance Of Face In Weldment Assembly Environment

Jan 29, 2013

I was wondering if there is a way to change the appearance of a face in a weldment assembly environment. I have a weldment which in the machining process a part of weld bead as well as a portion of one of the components is machined down (spot faced) and I need to change the appearance of those face to polished, but it doesn't let me do that?

AutoCAD Inventor :: How To Create Multiple Frames In A Single Assembly Environment

Jul 3, 2013

Is it possible to create multiple frames in a single assembly environment? (i.e. Frame0001, Frame0002)

The members all lump together in one Frame regardless of when they are created in the workflow.

I know there is a workaround for this by making each frame in its own assembly...but that will be more cumbersome than it is worth in this application.

Right now I have just created folders in the Frame0001 to sort things out, but the folders are not very flexible as far as moving things in and out or reordering...it is a pain.

I've used the Frame generator to create my existing building columns, existing platform columns, and existing handrail. I'll be using the frame generator pretty soon here to build a new platform, which I would love to keep separate from the existing steel.

I suppose I could save the current assembly and insert it into a new one so I can add the new equipment, but I'd rather avoid large subassemblies like that. Seems like it would be a lot easier to just have an option to create Frame0002.

Maya Animation :: IK Without Joints?

Aug 22, 2013

I have 3+ Nurbs Circles that I have parented up in a hierarchy and now want to use them to create an IK chain.I can create a chain with a joint system, but can I create it with just my curves?  I have tried using the IK handle tool and it requests that I LMB on the first joint and nothing happens.

Maya Animation :: Object X-ray As Joints

May 3, 2011

Is it possible to make an object, say a NurbsSphere to always be on top of the geometry in the viewport, like x-ray on joints. That way, I could use a small sphere in say the Elbow as a controller, and it could be inside the mesh but not hidden. Much like what you see here:

Is that really not possible?

Maya Animation :: Rig Moves The Joints But Not The Body?

Jan 10, 2014

I picked up two characters that I had working just fine about 3 years ago. Somehow, when I imported them into the same file, the skins came unbound. Annoying, but not insurmountable--rebind and weight painting took a couple hours. However, while the controls move the joints and deform the skins, the global move controls do not move the characters. It seems like the main mass of the bodies are stuck in place.

Maya Animation :: IK Handle - Rotation Limits On Joints?

Jul 13, 2013

I have set rotation limits on all  of my joints in a rig.  But when I move the Ik handle, the joints all rotate in however they want.

What can I do to make it so that when I move the IK handle, the joints are constrained to their individual limits?

Maya Animation :: Adding Prop Joints To HIK Characterization

Feb 24, 2012

I've been trying to feel out the pipeline for creating HIK rigs and jumping back and forth between Maya and Motion Builder. In Mobu, there is a way to add prop joints to a character's definition, but I haven't found a way to do so in Maya.

What I have done, is created the joints as necessary, and then created custom controls that the prop joints are constrained to. It's a simple parent constraint, so nothing too tricky. However, when I go to File-> Send to Motion Builder, the joints that are constrained are offset from their proper positions by a distance similar to their offset from the origin of the scene. The only way to get them back, is to turn off the effects of the parent constraints.

The controllers, and constraints transferred into Mobu fine, it seems. So I'm not sure where the discrepancy is. It would be ideal to be able to add these joints into the characterization step in Maya, to simply move them about with FK controls. What the best way to set this up would be? Is there a way to add prop definitions to a character in Maya?

While the original question remains, I found that the prop controls I had in my scene, were off from their proper positions, by the exact relative amount from the origin in the maya scene. Even though I froze transformations on the controls, coming into Mobu, they were put back on somehow. After selecting them, and setting their trans values to 0,0,0, they were put back into the correct position.

Maya Animation :: Selecting Multiple Joints For Setting A Keyframe

Apr 18, 2012

Trying to animate a rigged model for a class project but I'm running into problems. If I, for example, pick the joint at the top of the hierarchy, in the main view it appears as though everything gets selected. When I try to set a keyframe for the whole model, though, it only gets set on the actual joint I picked, none of the ones below it.

I looked at things via Outliner and see the same problem: I pick a joint there but the ones below it show as unselected in the Outliner window. Right now it appears the only way I can select multiple joints to set a keyframe on them all is to manually expand the tree in Outliner and then explicitly pick each one with command-click or shift-click. If I select an un-expanded joint section in the tree the hidden joints do not get selected, and if I expand the tree and pick a root node the ones below it are not selected.

I have tried this on three different models, including one I rigged myself, and the same behavior is present across all three.

Is this normal behavior for Maya animation? Is there some configuration setting that will change this so I can select an entire skeleton tree via the root node and have all of them accept a keyframe?

I'm running Maya 2011 for the Mac, on OS X Lion, with service pack 1 installed.

Maya Animation :: Facial Joints Versus Blend Shapes?

Sep 17, 2011

I want to rig a face for animating. (not for a game). and I can't figure out which is better and why: having all joints, and those joints driving parts of the face.. or just making blend shapes for all expressions like smile, angry, sad etc....

I know blend shapes won't work for games, but I'm planning to do mmo's anyways so I'll never need a complicated joint setup for faces... but as far as film, what works better?

AutoCAD Inventor :: Studio Assembly Animation - Part Parameter

I have an assembly inside of Inventor Studio.  One of the parts inside of the assembly has a parameter that I would like to animate. When I select the "Parameters" function within the "Animate" tab on the ribbon, I get an error:

"There are no favorite parameters defined."

This worked fine when I tried the same thing with only the part inside of Inventor Studio, but not when the part is included inside of an assembly.

AutoCAD Inventor :: Creating WorkPoint In Assembly

Nov 11, 2013

Simple question: How do you add a WorkPoint in an Assembly? I was hoping to find something like:

dim pt as new point ( 0, 0, 1)
oPartDef1.workpoints.add(pt)
   ~OR~
dim pt as point
pt.setlocation(0,0,1)
oPartDef1.workpoints.add(pt)
[code]....

It seems like I need to make a geometry (i.e. thisApplicaiton.TransientGeometry.CreatePoint(0,0,0) ) but I cannot find this feature for a component Occurence.  I don't want to make a "Global" point, I want to make a point "Local" to a particualar part.

AutoCAD Inventor :: Creating A Flexible Assembly?

Jan 11, 2012

I am wanting to create an assembly that I can manipulate and `pull about'.

To describe what I have and I want to acheive try and picture this very simplistic layout :-

A length of hose 50 meters long.

Another length of 50m long hose 2 meters directly below it.

The 2 lengths of hose rigidly tied together at 2m intervals with a small diameter solid bar and clamps around the hose.

What I need to acheive is :-

An assembly showing the above items in a long straight 50m run.

(I have no problems with creating this assembly.)

From there though I then need to be able to create an `S' shape, with the hose staying at a fixed radius where it is rolled to form that shape, both hoses must stay inline with each other at all times.

If you can imagine how a hose would react as you rolled it in reality I want to try and replicate that within my assembly if it is possible?

I realise I could create one long flat assembly then create another seperate assembly showing it in it's rolled up `S' shaped state but that is not what I am wanting.
