I’m having a problem with a part being skewed after it’s been linked to another part. This only happens when the part that it was linked to rotates.

The unit basically consists of 3 short cones which at tilted at 30 degrees to the horizon and each on spins on it's own. In order to get them rotating properly I had to assign a TCB quaternion controller. With these three 'cones' rotating on their own I need to have the entire setup rotate with these guys still rotating individually.
google images "oil drill bit" to get an idea of what I'm putting together.
So I link these animated cones to the parent main shaft. Once I do this I lose all the rotation animations I had given to these cones.
The problem I'm having with Skin Morph is that it's skewing my vertices side-to-side locally.
I'm using Skin Morph to better preserve the volume around the two joints of each finger of my hand model (See Arm1).
The two skin morph targets were created for the index finger while it was in the same position as the second image (Arm2).
I repeated this process, creating skin morph targets for the other two joints on the three other fingers and on the thumb.
The problem comes when I rotate the knuckle joint in any axis, in the third image (Arm3) I've rotated the knuckle downwards and you can see the vertices affected by the Skin Morph modifier have skewed to the left. When I turn the modifier off the vertices go back to their original position - so the problem isn't being caused by something like non-uniform scaling of my model (I reset the transforms before skinning).
The fourth image (Arm4) just shows the basic child/parent relationship that I've setup with the Bones and SplineShapes.
The fifth images show the (perhaps strange) position of the Driver Bone Matrix and the Morph Bone Matrix which could be constributing to the problem somehow.

So i have a box with a left side, right side, top, bottom and a door in an assembly.I've linked all the parameters to the 'right side component' so that when i change it, it updates all the other parts in the assembly.
What I want to accomplish is to be able to use my BASE SIZED BOX ( say 500 x 500 ) to create many different sized boxes.The problem I have is when I save the assembly as a new one and save and replace all the components for the bigger box, all the components still reference the old part ( 500 x 500 right side component) instead of the bigger ( 600 x 600 right side component.
how to link parameters, don't know ilogic, and just know the basics of assemblies and part modeling.
I dont know if this is possible or not. What it is, is that we use skeletal modelling, so we use intelligent "master sketches". Now we are just starting to use frame generator also and we want to combine the 2 methods.
An example of how we work is this.......
Lets say, we are designing the base of a basic frame. Now, we sketch in the profile of the RHS that will run along the front of the base and we also sketch in the elevation view of this RHS (see snip 1). This gives us 2 sketches to derive in to create a new part of RHS.
If I change the size of the profile of the RHS within the "master sketch" the newly created RHS part will update to suit. This also applies if I change the length of the RHS within the elevation view within the "master sketch".
So, now we want to add in a 5mm thick plate that sits flush with the top of the RHS, we sketch in a 3mm thick rectangle and make the top line colinear with the top line of the RHS profile sketch (see snip 2). We would then derive through these sketches and use them to create this plate as an ipt.
So now we have 2 parts, 1 length of RHS and 1 piece of plate. If we place these to parts into an assembly and ground them to their "root" then the plate will be sitting flush with the top of the RHS.
If I change the profile of the RHS to 50mm taller in the sketch, then the plate will move up to suit and stay flush with the RHS in the assembly.
NOW, what we want is to use frame generaotor along side this method. Instead of deriving through the first 2 sketches to create the the RHS, we want to create the RHS using frame generator and the elevation sketch BUT what we also want is when we change the profile sketch of the RHS, the Frame generator generated part updates to suit the altered sketch. The reason we want this is because we control all our full assemblies using sketches.
Lets take the same bunch of aforementioned sketches and create the parts using FG.
So I have the RHS profile sketched out at 100x50 and the plate sketch sits colinear with the top of this.
I then go through the motions to create the RHS within FG.
I choose RHS from the drop down menu, then choose 100x50 from the "size" drop down menu. I then use the elevation sketch to specify the length.
Now if I increase the size of the RHS (to 150x50) within the sketch, the plate will move up to suit BUT the actual part of the RHS which was created using FG will still stay the same size (100x50), and the plate will be shown as floating within the assembly!!!
If I do it the other way, i.e. change the size fo the RHS within FG, then the sketch will still show the original size and the plate will still sit flush with this original size. This will show the plate as sitting too low in the assembly!!!
Is there anyway at all, that we can link the profile sketch dimensions to the FG generated parts, so that if we edit the profile size of the RHS to a larger or smaller size then FG will automatically alter the generated part to suit the profile sketch???
Is this at all possible???? Or will we just have to alter both the sketch AND the FG part? We really don't want to use adaptive parts within our assembly, we always just control our assemblies with our "master sketches".
100 frame animation setup. created a slice plane on a box, animated it, copied it to a copy of the box with different material, tried to link a deflector created in the left view port to the slice plane and it doesn't exactly line up/match.
checked animation curves, there was only 1 on the slice plane, and tried linear or curved, no difference, the deflector doesn't line up exactly.
tried wiring it to each box, recreated a couple times. the attached picture shows the slice plane and how it lags behind the gray/white slice modifiers.

How come baking some part of animation in graph editor deletes everything before and after the part i bake and how can i bake that part while leaving the rest untouched?
View 2 Replies View RelatedI am trying to find out if it is possible to hide parts of a mesh while I skin certain parts of a mesh using biped . Here is what I have tried. Below my skin modifier on my stack is my edit mesh. I open up edit mesh and select the faces I would like to hide and hide them .Then I return to my skin modifier and skin parts of my mesh. but then I reliased that my biped is no longer skinned to my mesh if I hide a porition of the mesh. Even When I unhide the faces the mesh is no longer skinned to the biped. The biped moves but my mesh no longer follows. I tried deleting the skinned biped bones on the skin modifier and re adding them but it still did not do anything.
I know there must be a way to hide parts while you skin. By the way I am using MAX10
I have several parts that at a point in time come together and need to rotate together around a common point. However, when I animate them it will only let me rotate them around each individual part's axis. How can I temporarily link these parts to a parent dummy object so that I can rotate them together? I want this to happen midstream in the animation and after the rotation I will be decoupling the parts and having them do different things..

View 1 Replies View RelatedI have drawn a shape as a template for a picture which I want to skew into the same sort of shape. I have tried various tools (including Shear, Free Transform, white arrow and arrow +, ...) but I cannot get it to go into that particular shape, though some have moved it towards the shape, but not exactly.
I thought this would be easy, just using the white arrow and selecting one corner point at a time, moving it to the place I want it to be.
Here is the shape (the yellow part):
How can I get my picture into that shape and angle?
I find at least once every project I need to do something like this (skewing/forshortening). If I make a section view of a set design (cutting right through the stage), I'll do that by taking my set elevations and skewing them.
the solution, painstakingly outlined in VIDEO FORMAT, and annotated..?
When you get back up and running, here's a full demo of both the 2D and 3D methods described [URL] ......
Is there a way to have the bitmap fill of an object stretch a skew with the object as the handles are moved?
View 1 Replies View RelatedWhen I use the move command to, let's say, to move a floor plan (drag to new location on the page), some of the lines in the "moved" floor plan are either skewed or missing. I'm able to "cut and paste" as welll as "copy with basepoint" w/out problem.
See attachment below.
How might I correct this problem?
There is a script here but it is not finished and I don't know if it ever will be... Any tool that can do this in AutoCAD.

If I try to warp after doing one of these two transformations, I am unable to click on any of the points or handles. The only thing it will let me do is alter the lines, but the points themselves cannot be moved. What am I missing?
View 6 Replies View RelatedThere are 3 elements there. the top of the clap board was placed before i started tryinbg to create the slanted dashes that are on the average clapboards. The white dash was skewed using Object > Transform > Shear. Then i attempted to rotate it to fit.
I need 4 of these skwed white squares / trapezoids on the top along with 4 to match on the top of the larger potion of the clapboard. I do not want to eye it as it will be a part of a logo.
What would be the best method to use?Is there a way to draw the 4 rectangles on top of a perfectly horizontal long black rectangle and skew the white dashes at the same time?Is there a way to skew based on the dimensions of the longer black rectangle?
I am trying to replace a custom part - created from a content center part - with a copied part with a different name. (I am using the replace tool in an assembly.) However, Inventor is not replacing the part with the part I pick but rather the content center version of it.
View 3 Replies View RelatedOn the main sheet of my drawing I have the overall Parts List. Shows almost all parts except for the few that we don't want to list. On the second sheet I inserted a Parts List to show only parts that are shown in a detail on that page, made the rest non-visible.
On the main sheet there is an item (#13) that has a QTY of 3. Two of those Three are optional parts. What I'm trying to do is insert a custom part into the Parts List, give it an item number of 13A and put in the description "OPTIONAL", then do an Override in the balloon to show 13A.
I get it in the Parts List, Apply it, close it, save the drawing. Looking at the Parts List, item #13A is there, but item #14 is gone. I go back into the Parts List and 13A is there and there's a blue box around the item # and the description. I uncheck Static Value and number 14 shows up (item # and the description).
Then I go over to sheet two, open that Parts List and it lists 13A at the bottom with all the info I added in sheet one and it's non-visible. Go back to sheet one, open the Parts List and there is no 13A to be found.
I am working on an assembly that is designed around a box (bounding box) that could change size. I modeled the bounding box and placed it in a new assembly file. All other parts have been created within the assembly by referencing that bounding box with starting work plane and project geometry.
The problem comes in when I change the bounding box dimensions. The work planes for each additional part, which were defined by the faces of the bounding box, do not move when the sides move. Also, my projected geometry is not updating correctly. This is a simple box, with all 90° corners. So, all associated parts (at this point) are just rectangles.
My parts list on my idw do not update when I make changes to the model. Specifically, I have deleted a bolted connection on my design and replaced with a different components but the parts list table does not update - all I see is a lightning bolt in the browser next to the parts list but I cannot update it here.

I was using virtual parts to add nuts and bolts to a drawing in 2013
I can make a VP bolt in the assembly, no problem, set it's size, weight, etc.
In the VP itself, there is no option for number of bolts I want it to emulate. For arguement's sake the weight was 1 pound per bolt (they are big bolts).
I can go into the BOM and say quantity 60, hit done and save the assembly.
If i open the drawing, the parts lists shows 60lbs for the 60 bolts total - which it should when summing the weight.
The problem is the BOM/assembly. If the weight of my assembly (without bolts) is 10,000lbs, the assembly sees the VP weighing 1lb and says the total weight is 10,001 lbs. Am i going to have to pattern a fake part to get this to work right? Shouldn't the total weight take into account the quantity set in the Bom??
Is there a way to display the density of materials that are assigned to varius parts in the parts list on a drawing? I don't need the mass of the parts I just need the material density to show up next to their respective parts.
For example, if I have a part with [steel mild] material assinged to it (no matter the size) I need a column in the BOM on the drawing to show: 490.684 lbs/ft^3. "Worry when there's something to worry about."
I have an assembly with a lot of purchased parts. I need to create a buy out list for purchasing. I've done this many times in the past and have a template set up for this purpose.
So now the problem, In this assembly, I have subassemblies showing up on my parts only parts list.
One of the subassemblies cinsists of two purchased parts. Both parts are set to purchased in the Bill of materials. If I do a parts only list on this assembly, it works as expected, showing two purchased parts. However, if I put that assembly into a higher level assembly, A parts only parts list shows the assembly instead of the individual parts.

Been working over an idw MANY times due to project lag.Today I opened it up and tried adding balloons to an already ballooned assembly.
The parts list has not changed, and is "structured".But, if I try adding balloons, they tag each part, not the entire assembly.
Also, I verified this by trying to add another parts list, which defaults to "parts only".
I can't show my data set, b/c it's HUGE, plus it's proprietary.

I have a .idw that I'm trying to make a parts list on. I select parts list and highlight everything. There are two screws that are not showing up on the parts list. I cannot select them manually either. It's acting like they are not there. Even if I do a complete parts list (adding the assemblies parts into one big list), they still don't show up.
How can I select these parts? What is wrong with them that they do not show up in the parts list?
I have been working with an assembly today where it is ideal to mirror parts and have figured out how to reuse the parts rather than create new parts. Now I find that when the parts are mirrored, they ate not retaining the mates. Where do I find the setting so they either retain their mates, or prefferably retain the mirror so that if I move the origional, the mirror moves as well?
