AutoCAD Inventor :: Stress Analysis Constraints With Both Translational And Rotational Movement
Jun 13, 2013I'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?

AutoCAD Inventor :: How To Constrain Movement In Slot
Jan 9, 2013I 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.
I attached model files. I use Inventor 2013
AutoCAD Inventor :: Suppressing Translational Constraints
Aug 8, 2012I am working on an Inventor Studio animation and have noticed a problem. It appears that it is not possible to suppress/enable translational constraints. My assembly has a translational constraint that I suppressed in order to “explode” the assembly. I am animating the assembly process. Once it is put back together, I need to enable the suppressed translational constraint in order for the model to function properly.
I thought about recording two animations and then splicing the two videos together, but I am worried about the transition. I really need it to be a smooth transition in order to work.

Jul 23, 2012I am trying to produce an iFeature that can be used as a punch/slot within a sheet metal component.
I have had minor success creating basic dimples before (simple revolved features), but this time I require a more detailed feature. I haven't been able to produce this part (see attached) as an i Feature. I believe it is because I have used a loft.
What alternatives are there? (I feel if I could get a good grasp on the limits of iFeatures that I could really make my modelling more efficient and versatile).
AutoCAD Inventor :: Multi-link Car Suspension Assembly Drawing - Rotational Joints Binding
Nov 28, 2013I've been teaching myself inventor over the past couple of months so I can design the rear suspension setup for my car.
I've got the IRS modelled with enough detail to show my engineer the concept, but I want the suspension to "work", ie each link will move as the suspension flexes.
I'm attaching the arms (blue, dark green, red and yellow) to the cradle (orange) using the joint command, and selecting "rotational". This works fine and the arms can swivel about a single axis as they should. But as soon as I attach the knuckle (lime green) to the other end of all the arms using the same type of joint (except the joint with the blue lower control arm, which is a ball joint), nothing will move.
I understand that in real life, each joint has a bit of "slop" in it, allowed by rubber bushings, which prevents the whole setup from binding.
To my uneducated mind, the solution would lie in one of 3 methods: Convert all the joints to ball joints (I'd like to avoid this if possible) Add some kind of flexible rubber bushing to all of the joints (probably not possible) Get rid of the rotational joint constraints altogether and somehow mate all the parts to each other using work points, rather than a cylindrical bolt and eyelet, so that each arm has full range of movement in both the X and Y axes.
AutoCAD Inventor :: Center Line On An Open Ended Slot
Oct 7, 2013how to put a center line on an open ended slot. Say in the front view you can see the radius of the slot with horizontal tangents running to the end of the object; this isn't the problem. When creating the top view, you only see one hidden line indicating the arch, but the other side is just open to the end. You have no means of finding bisectors.
I've added a jpg file, looking for the center line in the top view.

Jun 26, 2012I've managed to hack together some code to draw a rectangle and dimension it. Now I want to constrain it to the origin. I figure either using two dimensions from a top/side to the origin and setting the dimension as half of the other respective dimension would work. Or constraining the center point of a top/side line to be vertical/horizontal to the origin.
The problem I'm having is I do not know how to reference the origin. So until I figure out how to reference the origin point I can't use either method.

AutoCAD Inventor :: Speeding Up Constrain Execution
Oct 19, 2012SO what is everyone say, trick about speeding up constrain execution. I have started working on this new project with 2013. And i'm finding myself losing alot of time. Basicly what i do is insert part from our database or content center and assemble them. So 80% of my activities on inventor are constraints. Right now i have this assemblies 175 / 156(small to me). And executing a constraint is minimum 4 seconds each time. If you consider that about 3 contraint is needed for each piece and final total part will probably be around 1000. i'm losing alot of time here
Yeah, i am not using preview. Why is inventor recalculating that much each time? Is it doing a rebuilt after each constraint?
What have you done that really increase the excution time of constraints?

Dec 31, 2012I am trying to determine how to properley constrain the assembly below, so that the compression of the rubber gasket will be properly indicated.
Currently I am seeing the deflection of the shelf in the downward direction, but I do not see any indication of stress in the gasket behind.Currently the gasket is "bonded" to the steel tube the screws are bonded to the shelf bracket and the steel tube.
I put in "work axis" at the center line of the shelf bracket and the CL of the gasket, but I can't find a way to constrain to a work axis.The file is too large to upload here...
AutoCAD Inventor :: Constrain Component In A Track
Nov 25, 2012I'm trying to make a constraint allowing the dark smaller cylinder (1) to run in the copper track (2). I want the larger cylinder (3) to be able to rotate around its own axis, while everything is rotating around the Z axis. I've successfully constrained the parts so that all the parts can rotate around the Z-axis but when I constrain the smaller cylinder (1) with the tangent constraint with the track (2) the smaller cylinder is not able to move around on the face, it's just glued to the face.
I want the smaller cylinder (1) to recognize the copper faces as solids (so that it can't intersect the surfaces), this would allow the proper movement. I've attached an image of the parts.

Aug 4, 2013Is it possible to have a tangent constrain on multiple curves?
see enclosed rough sketch, i would like the curved free end or the arm to be in constant contaced with the wavey top line on the other part, the wavey line is constructed as 3 curves but i can only get the tangent constrain to apply to one of the curves.
i would like the tangent constraignt to move between the curves so the part stays in constant contact with the wavey line. this is just a mess about sketch i suppose a real world instance will be a wheel following a shaped cam plate.
AutoCAD Inventor :: Sketch Changes Constrain Status After Rebuild
Oct 22, 2012I have a sketch that Inventor changes its status between under constrained, over constrained, and fully constrained depending on dimensions (makes sense), and wether I rebuild the model (WTF?).
Steps to reproduce:
1) Open the attached .ipt file.
2) Examine Sketch11 (under Face3) It should be fully constrained.
3) Exit the sketch. Open the parameters dialog and change the value of "angle" from 45 to 60. (If you get an error message change it to 50 first, then 60. It's a work in progress.)
4) Re-examine Sketch11. It is now under constrained.
5) Exit the skecth and go to the manage tab. Click "Rebuild All".
6) Re-examine Sketch11. It is now fully constrained.
7) Scratch your head and post back with your theory.

AutoCAD Inventor :: VBA Script To Constrain Multiple Parts
Jun 28, 2013Lets say we have a plate with 100 randomly placed holes on it and 100 parts to attach to those holes. The parts aren't content center parts so they can't inserted in an easy fashion and the random hole spacing makes component pattern useless. The parts would normally be constrained using the insert command and you'd have to do all 100 separately. Would it be possible to make a script that would let you select the 100 parts then choose the selected geometry on one part and then a hole on the plate. It would apply that insert constraint and automatically select the same geometry on another part so you could simply select another hole. Then rinse and repeat until all the parts have been constrained to holes on the plate.
If something like that is possible it'd cut down the number of clicks greatly and also panning/rotating to select the different parts and holes on the plate. This isn't a daily thing we'd be doing, but it comes up enough in large assemblies it could be very useful. I haven't done any scripting for things inside parts/assemblies so I don't know what's possible while scripting.
