I am trying to anymate a chain using rigid bodies.However, when I try previewing the thing, my chain links just snap and the whole chain blows apart.
Anyway, it appears to have something to do with interpenetration of the links. I'm sure it is easy to fix just by changing some numbers somewhere, Now all I need to know is which numbers and where they are located...
I though rigid bind wouldn't allow any weight deformation of any kind, was i right because it doesnt seem so here, how can i get rid of any weight deformation anyways.
View 2 Replies View RelatedI still don't know how to simulate the following :
My system is basically a clamping device that works with a cam and a metal plate. When loose, the metal plate remains straight :
When clamped, the metal plate bends like so :
As far as I know, the Dynamic Simulation Tool can work with rigid body parts and you later export the simulation to the FEM Tool. I thought I could use a spring-link that would behave like the metal plate but I must admit I don't know the relationship between the stiffness of a spring and the elasticity of a metal plate.

I now use the magic wand tool to select most of the selection i want to cut out. But as soon as the "rest" (background) of the pic is sorth of thje same colour then this won't work.
I then go to paint and add an outline around the selection i want to use and start all over again in PS.
Layers used have individual chain link options. (CS1)
The way it is handled now, is awkward and time consuming.
If you want to link layers that are not next to each other, you shift-select all the unwanted ones in between as well. Than you need to de-link those in a second go. (By moving down to buttom for each single layer you need to deselect)
Is this supposed to be a smart improvement?
Is there an on/off option to have individual chain link with every layer, that I have missed?

View 1 Replies View RelatedI have a simple character with two a leg. The IK chain goes from the top bone to the bottom nub. When I move the ik helper around, the knee does not bend, even though there is a joint for it. Instead the leg rotates only at the top.

The bones are all connected correctly as well.
I am working with a rig that has arms and legs in which the upper and lower sections (Thigh, Shin, Upper Arm, Forearm) are composed of chains of bones in and of themselves. I have included a screen shot to show a simplified example of what I mean.
When working FK, of course, this is no problem at all, but sometimes I'd like to be able to use IK solvers to make placement tasks easier. Unfortunately, applying an IK solver means the bones forming the upper and lower parts of the limb also bend as the limb bends. In the screenshot, the bones on the left are an example of what sort of limb I am dealing with, the bones in the middle show the effect of using an IK solver (note the bend in the upper and lower leg) and the bones on the right show what I would like to achieve using IK.
So, is there any way to lock the motion of those bones composing the upper and lower parts of the limb so they won't bend as part of an IK chain? I'm using Max 2010 by the way.
I am currently creating a chain block to be animated later on. But, I do not know how to constraint it.

View 9 Replies View RelatedI found a VBA-code on internet which turn off all work features (plane, axis, points) in all documents in an assembly.
I want to modify it so it turns of all surface bodies instead. I use skeleton modelling where i only want to keep the solids visible and not the surfaces. When I run this iLogic rule all solids get turned off instead of surface bodies.
This code works (when edited) for axis, points, planes, allworkfeatures etc.

I am now modeling elements for silicone formwork for casting elements of epoxy resien.
I would like to schow idea of this formwork. For this I would like to make part representing silicone part of this formwork. It is contained in aluminium "cover" for convenience of use.
In assembly I have placed may model, and aluminium elements representing "cover" of formwork.
I am trying now to model silicon but it is quite hard. I can not use "derivered part" method to substract model and cover elements from some big block body because coordinate systems do not mach in all elements.
In Part there is "combine" function but it only works with bodies mabe within this part.
Is it possible to substract one placed in assembly from anothe part in this assemby?
how do i get the effect of a super big head ( not by liquify ) with a small body of a person in a complicated background? i do know selection methods using extract tool, but i need to maintain the resolution whilst upsizing the head, and if i downsize the body, there's no background to go with.
View 6 Replies View Relatedwhat I do need clarification on is the statement in this warning "One or more bodies which are thing being treated as solids". Does this mean that the bodies that were detected fall under the criteria for being a Midsurface or Offset and that the user has the opportunity to apply these commands in order to make the analysis more accurate? So if I were to ignore this and continue with my analysis, the members will still be treated as a solid and not as a shell and/or surface (which is what the Midsurface/Offset command produces)? The members I am using that have triggered this warning are HSS 2x2x0.125 x 12' long.

View 5 Replies View RelatedI have a model with solid bodies. I have used the combine feature to make cuts outs in some plates. The geometry is complex to model so Extrude cannot be used for cuts.
The body used for the combine can be at different angles and sizes. Due to this some of the combine features will not be needed or have no effect. This leads to the error message:
" The feature as specified did not change the number of faces (and may not have affected the part). Accept the feature that resulted, or use Edit Sketch or Edit Feature to change the feature definition." Is there anyway to suppress this feature automatically using i Logic?

View 6 Replies View RelatedI have an assembly file for a fan casing. We reuse this model and scale it up and doen depending on the size of fan.
For transportation we split the caing into several parts and join using flanges. The number and angle of splits changes depending on the job and geometry.
To model this we share a sketch through the parts and use the split solid command to split them.
I would like to able to create sub assemblies from the main assembly so that drawings and masses can be obtained for the sub assemblies. However, the 'Demote' command does not allow you pick individual solids from a multi solid part.
I have tried creating new parts from the split solids but these are not in the correct location as they are not constrained correctly.
Is there a way to use the Demote command as I am proposing? or is there a different method to split my parts?

I'm trying to animate a couple of bodies along a path with a workpoint that will move the assembly at the beginning created using a rectangular array along the path.

How I constrain the other body to follow along the path with the ride points as labeled?

Actually, I need to modify part color. But in some cases, the part color and the solidbody color are not the same. So I need to modify the Solidbody color, to match the part color.
