I'm trying to scale a spring (which is actually a renderable spline). I want it's scalable boundaries to be controlled by two other animated objects.
I thought a simple FFD modifier with a linked xform modifier to the control points would work, but unfortunately it won't let me link control points.
I use inventor 2011 and i want to create a spring animation. I followed this video step by step but when i constrain the upside and the downside of the spring to those plate objects i get an error.

I'm trying to use the spline IK system to animate a linked 'train' on a path.
There are 4 segments which are joined with a universal coupling. I can only get one segment to actually follow the path, as the others don't follow at all. I've attached my example file.
how to design and simulate a extension spring (not compression spring) in Autodesk Inventor 2012.

The number of bones in the chain upon which the Spline is set doesn't seem to affect the number of control vertices I have to work with when creating the spline and I can't find a way to increase the number. I'm trying to animate a fish but finding it difficult to get a smooth wave to travel along it's length with only four control vetices.

View 1 Replies View RelatedI've got a 2 bone chain that I have attached a spline IK to with a flex modifier on the spline. This was working pretty well however, once I skinned the mesh to these bones I noticed that when I rotated the 2nd bone it would seem to pop on a different axis. It was hard to spot at first because it popped between 2 frames, popped 90 degrees and seems to happen at the same rotation amount (can't recall exact degree at the moment).
I turned off the flex modifier and it is still popping so I'm assuming it is from the spline IK. Is there a way to prevent this?
I have problem with animating camera along a spline using path constraint. The spline has been spline normalized before added to the path constraint. Then I add besier floating to be able to slow down the camera.
The final camera seems to move not smoothly. This can notice especially when the camera are further away from the origin (0,0).
Some says it's because of Max's coordinates is not fine enough which can clearly proved when import autocad file which located very far from the origin into max and most vertex will be shifted from where it should be in Autocad.
I am working on a rig right now and I'm trying to do the Isner Spine from the Body Language Advanced 3D Rigging Book.
I did the Spline IK with the spine and I have everything stretching fine but when I made the CVs into clusters and parented them to the controls, when I got to translate the rig, whether I use the Root CTRL, Main CTRL, or whatever, the spine translates twice as fast as everything else. The clusters and everything in the lower body moves normal and everything about the head is moving normal..
I know in other situations with curves you have delete history but I can't delete history on the joints and I can't come up with any solution. I can attach a file.. not all the controls are done right now and I haven't reparented the wings correctly so just ignore that.
I have a skeleton with baked motion capture keys on every frame. I'm wondering if there is a method to convert these baked keys to curves, so it will be possible to start cleaning up the animation. I'm fairly new to dealing with mocap. Perhaps there is a method for achieving this in Motion Builder rather than Maya, that I'm not aware of?
View 2 Replies View RelatedThere are a few Aluminum Composite Panels represented in my model.To cheat I use RENDERABLE LINES for the Joint lines so that they show up when Rendered.However, I did something stupid -- like erase all of them. They must have been grouped or something. But they are ALL GONE.SO, I went to earlier versions of my model and tried to do the following:
1. Merge: Fail. I see the Gizmos for the lines, but they are a no show in Wireframe and they do NOT render
2. Import .3ds: Fail. All I see are Green Outlines of where they should be AND STILL do not render.
3. Xref: Fail. Same as attempt 1.
QUESTIONs:
-Why are these lines not able to import, or be seen?
-What other solutions (besides redrawing them) have I overlooked?
I seem to be having a very strange and annoying problem with Maya 2013. I cannot change the rederable frame range at all and also some of the other rendering options! I had this problem with Maya 2012 but overcame it by borrowing a friends project file with all the render settings working and then saving a pre-set of those settings.
View 3 Replies View RelatedI'm trying to create an external involute spline (ANSI B92.2M) Fillet Root Side Fit 26.9mm x 1 mm x 26 teeth x 38 mm long using the spline generator with Inventor 2012. I created a test shaft"M-182-AMA.ipt" that is Ø26.9 mm x 38 mm long with 1 mm radius on each end of shaft.
I use the following steps:
1. After creating component "M-182-AMA.ipt" I select Design tab>>Power Transmission>>Involute Spline.
2. A window appears that has the caption "Involute Splines Connection Generator".In the Dimensions section I choose "Splines Type: ANSI B92.2M - 37.5 deg, Fillet Root, Side Fit, 26 x 1.00 x 38 x 5H/5h" and change the Length to 38 mm.
3. In the Shaft Groove section I use Create new, and I push the Reference 1 button that turns blue, I then select the od feature from the model and I get an error(see attached pic "error1.jpg).
I changed the 26.9mm od to be 27mm and it still gave me the error.

if I have a rig and an object which is skinned to it, what is the best way to enlarge a bone so that certain vertices on my mesh will look inflated or deflated?
I tried to some tricks with the Xform modifier: wiring it's Gizmo controller to a slider UI control so that I could increase and decrease its size without actually scaling it, but this doesn't have any affect on the mesh. I then tried creating morph targets for the bones so that I could again increase and decrease their size without scaling them, but it didn't affect the mesh either.
It seems that the only way to get the mesh to localy increase or decrease in size is to scale parts of your rig, but that's something I always try to avoid.

I'm using MassFx in 2013 64bit. When I apply any rigid body modifier to an object it looks fine but after I save and reload the .max file the scale & position of the rigid body is wrong. This seems random, I've tried switching to CM and Meters etc, nothing seems to fix it.

View 2 Replies View RelatedI have several art assets that I have already rigged, skinned, and animated. Unfortunately, the objects have to be re-sized.
There isn't a simple way to simply scale the rigg to match the new size, because then the transforms are incorrect, and the scale on the bones are no longer at 100%. Normally it wouldn't matter, but these objects need to go into a game engine, so it has to be at 100%
No, simply re-sizing the rigg and hoping to just 'reset scale' will not work either.
Save/Load animation will inherit the pivot points of the original animation and paste them onto the re-sized objects, so that does not work either.
Is there a way to transfer a rigg and save it's animation when an object gets re-sized? I'd figure that Autodesk would have made some kind of feature for this scenario, since in game production things will inevitably be scaled at some point.
It's easy to scale everything to it's new size... the problem is... how do I reset it's transforms without the rigg going bonkers?
How do I take the original animations and re-apply them to the newly scaled down version?
Say I have a series of keys, and I want to add exactly 1 or 2 spaces in between each key. is there a way to do that? rather than selecting chunks at a time and spacing them apart... like +=2 will move all the selected keys over 2 spaces all together. maybe theres a code that moves them with an offset?
View 2 Replies View RelatedI have a model that contains a spring dynamic that needs to be exported as FBX. However, the FBX exporter is unable to translate the movement of the spring and converts it to a static mesh. Is there a way to "bake" the movement/animation of the spring dynamic object which FBX will be able to translate?

View 1 Replies View RelatedInventor 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.
