I'm trying to make an assembly that would move. however I'm having trouble right now, when i try to move things by mouse, it seems they just go everywhere without respecting the constraints. At first i was using the drive constraint on the slider delete for the movement but it doesn't work either.
I am using inventor 2011 btw. Here are the files, assemblage.iam was working correctly but when i added the arms, they don't work ( assemblage2.iam).
When I rotate the drive shaft gear very slowly, the assembly follows the the correct motion path, (figure 1), however, when I rotate it quickly, the assembly snaps the linkages to an orientation that is not physically possible, but satisfies the geometrical constraints (figure 2). I can't use contact solver because I am using the adaptive function for my sub-assembly to avoid having to re-constrain many parts.
I have a damper, I started it with the bottom frame member, which was grounded at origins when it was placed and I built the rest of the damper from there. All my constraints for blades and linkages and all related parts were able to move (with the damper held in place in "space" by the grounded frame member.
For parts list purposes I need all 4 sides of the frame to be one BOM item so I demoted the 4 frame pieces as one inseparable assembly.
After that all motion is lost in the main assembly and I can drag it all over "space" since I lost the bottom frame member ground point. I can ground the demoted frame assembly to lock it down, and drive the constraints to make the damper parts move to create positional representations.
I guess I'm just wondering if I'm not really supposed to be able to "move" components arbitrarily and I should just be driving the constraints all the time in the first place...I'm just not sure why the motion is lost after the initial ground point is lost.
I'm looking for the best way to create a separate assembly out of various component parts in an existing assembly so that the whole thing can be placed in an assembly as you would a part, I know it's possible to demote components within an assembly but are there any other methods similar / better ?
We have an iLogic assembly with to parts in it. Maybe to cylindrical parts. The iLogic rules should do the following.
1. Start a Rule after open document.
2. This Rule starts a Rule in the first cylindrical component.
3. This Rule ask the user for a diameter.
4. The assembly gives this new parameter value to the second component
5. Then the assembly calls another rule in the second component to change it with the new parameter
Everything is working fine when the following combinations are taking place:
1. I open up the assembly out of vault or from a local drive or an accessible server drive
2. I insert the assembly as sub assembly in another assembly from a local drive or an accessible server drive
It don't work with the following situation:
- I insert the assembly as sub assembly in another assembly out of vault
Then the user becomes the dialog "Choose a diameter" twice.
I don't know why, but I have the idea it has something to do with the functionality of inventor to insert a component more than once. If you insert a component in an assembly Inventor gives you the opportunity to add more than one occurence after each other.
change that behaviour? Maybe a switch to change that inventor "add more than one occurence" behaviour.
I have encountered a problem with the Tube and Pipe styles.
As you can see, I have a rack assembly with a custom tube and pipe style. A wire as a tube in orange, and a tube support in white. Both have their seperate colorations at a style in the tube and pipe styles editor
When placing the rack assembly into the main assembly, it reverts to the coppor coloration I changed from the original style.
Steps I've taken:
Exported the styles .xml and Imported the styles into the master tubeandpipe.iam
Imported the user created .xml styles into the main assembly file nothing seems to work
I am trying to find the interior volume of an assembly (when am I not?!?!) by subtracting the assembly from a block that surrounds the most of it. Somewhere the assembly has a "leak" and I have been trying to use the Cross Section Analysis to track down where the inside lump is connected to the outside lump to be subtracted. Is there a less time consuming way to dynamically drag a plane across and get cross sectional views?
Even better is there a simple way to animate the analysis plane moving across the block so I can hopefully just watch and pause it when I find a leak?
My assembly has grown (about 50 parts) to where I need to consolodate some parts into subassemblies for reuse and alternate iterations of the basic design.
When I import the original parts into a new assembly, all of the constrains I created are not there of course.
I've tried creating a new empty part and then deriving a new part from the assembly, but I can't add, delete or edit any parts.
I looked at using Shrinkwrap, Substitutes, iParts, Multi-body Parts, and Multiple Solids but I remain confused.
In retrospect, maybe I should have created the subassemblies between the part and assembly stage but I didn't.
I want to be able to control the location/position of a component in an assembly. This is easy enough through the iProperties/Occurrence tab and then adjust the location of the X,Y, and Z offsets. Is this possible using iLogic? I have been unable to find a function to access via iLogic. Ultimately I am trying to translate a component about an axis not a pattern.
I have a two part duct fire damper assembly. The IDW has the combined two part assembly, which I know how to turn the CoG on, so that it can be dimensioned. The problem is each piece will more than likely be hoisted separately so I would like to show the CoG for each piece, not the combined master assy.is there a way to do this?

In SW I was able to create assemblies that had components with limited motion and then set them as "Fllexable" and allow them to move in larger assemblies. How do I do this in Inventor? I have a trailer with both the front and rear axles able to pivot. These axle sub-assemblies are both able to pivot as top level assemblies but when they are assembled in the trailer assembly the only way I have found to allow movement is to make one axle active and move it then activate the other nad move it. This doesn't work well if there are several interdependant subassemblies that should move together. I am in Inventor 2012.

How do you limit translation/rotation of components in Assembly mode? I'm volunteering as a teacher to some high school students and we're modeling a robotic arm using syringes as prime movers. I want to keep the linkages from traveling inside-out and limit the travel of the syringe plunger.
i'm developing a hexapod robot and i want to simulate the motion of the robot's leg. The mechanical of robot's leg contain a servo motor that variate your angle between 0 to 330 degre. How can i delimite the angle of servo's rotation?
Other questions, is about the fixation with bolts. How can i do for the motion simulation respect the connection of the bolt? when i do a dynamical simulation the parts that contain bolts don't stay joints, i have to do a rule of fixation with constrains?
I'm trying to design a gear system wherein a small gear rotating on an axle interacts with a large gear, held on an arm. The arm rotates about the same axis as the small gear, in the opposite direction. I applied the relevant motion constraint between the two gears. When I rotate the arm, the motion of the large gear rotates the small gear. However, if I just rotate the small gear, it freewheels, and the large gear doesn't move at all. This is a problem, because the machine depends on the independent rotation of both gear and arm-- the small gear has an input applied to it, but if I try to rotate it it has no effect on the large gear. I assume this is to do with the fact that the large gear's axis of rotation moves with the rotation of the arm.
I can't just throw it all into dynamic simulation, because I don't know yet what kind of torques will be rotating the arm and the small gear-- I know how they rotate relative to each other in terms of degrees, but that's all.
Essentially what I need to do is make it so that rotating the small gear turns the big gear, even when the arm is free to move (when it's grounded, the gears turn normally). I thought about using a contact set, but the gears (generated by Inventor) actually slightly intersect at the teeth, so that doesn't work.
Attached is an assembly that I created. It includes a timing belt, 2 pulleys, 2 shafts, and some profile lugs that are attached to the belt with a false tooth.
1. why can't I constrain the profile lugs around the radius of the belt? Also, when I created the belt and put the holes in it, they disappeared because they ended up in the radius of the belt.
2. Is it possible to create a motion constraint to this model, so that it moves like a real belt?
I would like to see if there is a routine that allows my iLogic code to detect if my assembly contains another assembly within it. If my assebly contains assemblies then I don't want "MyRule" to run. Else if it does then I want "MyRule" to run.
I'm trying to constrain a length of ACME threaded rod to a nut so that when the rod is spun or threaded it shows it traveling into the nut as it will be grounded. I would like it to work as a driven assembly or if I was to turn or spin the rod by the mouse. I've reseached this for the last 2 days and can not spend any more time on it so time to ask the experts.
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 am pretty familiar with Assembly constraints but I want to know how do you constrain/motion a screw or similar object to be able to turn appropriately whilst going up & down a threaded hole?
I am trying to constrain motion for the following design:
-Object constrained to vertical motion (a counterweight). -Object constrained to horizontal motion along a track (a slider).
A cable runs from the counterweight upward, makes a 180-degree turn around a pulley, runs back down, makes a 90-degree turn around another pulley, and connects to the slider.
When the weight moves down 10 cm, the slider needs to move laterally 10 cm.I don't care about modelling the cable, but I do need to have the slider move as the weight moves.
I will also need to model a case with a more complicated pulley, where when the weight moves down 10cm the slider moves laterally 5cm (again I don't care about the cable, just the relative motion).
Is there a way I can do this without creating a series of planes and cylinders and using rotation - translation constraints to link the motion of the weight to the slider?
Im working on a miniature train project of PLTW... I have completed the train and made a track for it... but i can't figure out how to create a drive/motion constraint that would make it go along the track.
(All the files are in a zip folder that is attached)
