AutoCAD Inventor :: Underground Scoop - Animate Movement
Jul 2, 2013
I am have a model of a scoop that I would like to animate to show motion and check for interference and clearance.I was told by a friend the best way to create and assembly is to create it as it would be built.
Doing this, I created the cylinders and added to them to the main assembly as an assembly, but I am having trouble controlling movement. I checked off flexible for each cylinder but using the mouse to try and position the scoop bucket and front frame is undesirable. I know I could apply mate constraints to check for clearances and movements, But seeing the scoop move in a regulated motion would be need. Could possibly be used for marketing purposes as well.
Is using dynamic simulation or studio better? I have heard good things about the Wasim Younis Series - book
Does his books get into how a model should be assembled/created before trying simulations?The boom moves off yellow cylinder and the bucket moves off the red cylinderA 4 way joystick controls this movement (hydraulically), is it possible to simulate a joystick to control this animation?
The blue cylinder is controlled by a 2 way valve, that steers the front frame.I know uploading a model is the best way to get fast accurate solutions, however this model is currently over 200 parts, so I figured a .DWF export was the easiest way to give you a visual representation.
Say I have 400 boxes and I want to animate each box to move up and down along the z axis randomly. How would I go about doing that? I assume somehow with the noise modifier, but I can't figure out how to get it to work with motion and not the shape of the object.
I'm working on a little trackless train at the moment. I have a working model of the train going around a curve, but I cheated a bit, by constraining the center points of the axles to the curve, and then had the wheels angles based off the drawbar angles.
I have began working on a more accurate version, where the angled wheels are what drives the carts around the curve. Long story short, if you have a thin playing card in Inventor, how can you restrict motion in the normal direction, allowing the card only to translate tangentially no matter how it is orientated in the model space?
Constraints are all based on relationships between two parts. Is there such a thing as restricting a part's movement in certain directions? The reason I ask, is I would like the wheels to follow the direction they are oriented (not being dragged in a normal direction, something resembling slip motion).
Essentially, I would like to do this without using contact friction between the ground and the wheel (which is what actually makes the wheel follow the direction of its orientation in real life).
I have a question about limiting movements. In real life, when you close a door it stops as soon as it hit its frame. I want to do the same in Inventor.
I have one problem and I would like to get your opinion how I could solve this.
I can't share models I have problem with, but I made another with the same problem.
I have two parts - one with slot, another with "pin". How to constrain the "pin" to always move in slot?
I had some ideas but non of them worked for me:
1. Use the Transitional constrain came first in mind, but it gives unsuspected results in this situation. Pin part is jumping around and ends up contrained in another place ir should be.
2. Contact solver kind of do the job, but it works quite bad. I gives no control or accuracy (i can not control how much pin is moved out)
3. I even thought of point on 3d sketch constrain, but it can not be done
How you would suggest to constrain the movement? I hope I stated problem clear enough.
In an assembly we can set driven constraints to drive parts etc.. or we can set the contact solver to show contacts.
Is it possible to set something like a driven constraint but so it is flexible between the set parameters?
when creating designs i like to move stuff around with the mouse to see how it works and the potential problems that might arise etc.. however i would like to still move stuff around with the mouse but restrict the movements with constraints.
so if you have a hingy flappy thing, the constraints would be set so it can rotate round the hinge as required but also an angular constraint could be set do it would work between set angles, say 0 to 50 degrees and if it gets to the limit it stops?
Is this possible, I think it would be very useful?
I have an assembly of a rod in a cylinder. When compressed, this rod sticks out 10mm from the cylinder. When extended, this rod sticks out 50mm. I am trying to create a drawing which shows the compressed state and extended state together.
Why is it that when you create the first constraint between any two components, the secondary component moves not only to satisfy the constraint, but also in ways that have nothing to do with the constraint. This is not occasional behavior, it happens every time.
I always have to stop and move the secondary component back out of the way to get to the other features I need to reference to continue.
I have to make a vice and I am trying to make the vice move. I am trying to use the screw simulation in dynamic simulation but don't know how to do it? I have only made the screw and the nut or the thing that it screws into to make the vice work.
I have a stress analysis result that doesn't make sense to me. I have a flat plate, that is loaded with 100psi equally throughout the surface. I have an array of bolt holes that are 120mm x 109mm spacing. When I do the simulation and look at deflection, I see more movement on the ends. I expected the movement to be consistent eveywhere?
Is this an Inventor issue, or are my expectations in error?
On a side bar, is there a better way to constrain holes than on their edges? I would think that would give errors on the stress levels due to the point (line) contact.

I'm attempting to model a spreader bar that we have in the workshop to estimate what load it should be certified for. It will be suspended froma 2 chain sling attached to the outside top lugs and the load suspended from the bottom outside lugs.
My problem is that simply constraining the inside faces of the top lugs with pin constraints results in erroneous values as the lugs can't move relative to each other. The other method I've tried is constraining the same faces using a fixed constraint and de-selecting the z-axis. Now they can move but I end up with large stresses inside the lugs as they attempt to resist the moment that's now been created.
Is there any way to select individual degrees of freedom (both rotational and translational) or at least set up the simulation in such a way that the constraints accurately represent reality?

While tracing a tree image using splines for a school project i have run into some problems...I am creating a pattern for a plasma cutter.
When i move the points of my spline sometimes it causes the whole spline to randomly move around and twist and turn where there are no points. Also sometimes when i open the drawing some of the spline lines are out of place while the spline points have not moved.I have tried to constrain all the points but it turned into a mess.How can i stop this from happening?
how I can create a sort of grill openings in the ceiling of an underground parking level? There are no ducts connected to it, it's just an opening between the underground level and the ground level, like a courtyard, for example?
I'm using 3D Max Design. I am unable to move an object on the Z axis of the gizmo. When I attempt to do so, a yellow line follows the path of my drag. I can move an object up and down only if I drag by all 3 axis.
I would like simulate this action or model this simple action I have in this sketch. It is pretty basic but I am drawing a blank on how I could see the max movement I can get with a 6" cylinder stroke.
Maybe more difficult than I am capable of, I could model it but don't know how to get it to move or rotate that would simulate the movement.
I would like to be able to show an animation of a flat plate of material converging into a half hollow sphere (like a bowl). Its easy to model the beginning and end stae, but I do not know how to show it transitioning from one to the other.
How to do this? I need it for a presentation to convey a design concept.
Is it possible to animate the Grounded function? I want the box (In the assembly that I attached) to walk through a line of stations, each one of them with a specific purpose, in a factory where the "solar collector" is being built.I am unable to switch between who's gonna be grounded during the animation, but maybe there's another way to do it?
Im a new user of Autodesk Inventor, working in a semi automation company, supplying conveyors and other related customized equipment. how to animate conveyor flow. attached is my file. a box and a conveyor line with straight, curve and spiral path. by self study I learned a lot of animation but this time I'm having problem because it's a combination of curve and spiral
I like the new(ish) feature where you can drag a section plane through a component, but is it possible to program a moving section and record it to an avi file? Is this something I can do in 3ds, Studio or Showcase? IV2013
I havent used inventor studio for animation too much. The question I have is why cant I animate a component in a subassembly? I can animate the parts in the assembly, but not any parts that are in a subassembly. Is this how it has always worked or just a 2013 thing. If it is suppose to be like this, I think it is ridiculous and pointless to have this feature. now I have to place all the moving part into the main assembly.

Using an old version of autocad 2012 in my laptop as backup loaded on Window 7. Everytime I used the snap mode it slow the movement of my cursor to move to specific location, but no problem using the Window XP.
1.) How do you recommend I model a rectangular spring? 2.) How do I apply the concept from the initial question and apply a curve to the spring? 3.) How do I mimic the properties of a spring in animation?
I am trying to animate a couple slides in to show their motion. I setup each different position in a positional rep in my iam. They work correctly. Next I went to Studio and created an animation that went from one PR to the next. I am using the sequence like PR "A" to "B", then PR "B" to "C", then PR "C" to "D".
The trouble is in studio it does not work like it does in the assembly. Watch both videos to see what I mean. It is difficult to explain without being lengthy.
The video shown here is what I am trying to show in Studio. See the reply to this message to see my clip taken from Studio.
I have two gears. In the assembly I have them setup to mesh correctly. I can drive the constraint on the pinion and the gear will follow it (some what). I wanted a better video of it, so I went into Studio. Now when I drive the constaint like before on the pinion, the gear goes crazy.

There is a rotational translation constraint set between the pair (= to inverse of gear ratio) that works in the iam, but it is like Studion ignores it. How can I animate this to show the gear mesh?
