Why can I not constrain placed objects with three constraints? Anything I place constrains with one constraint then is virtually fixed (without being) and cannot even be moved to allow for further constraining.
View 9 RepliesI am designing a vertical axis wind turbine just for some practice (just started using Inventor) and everything was going smoothly until I tried to "animate" it spinning. First, I set up a work plane that goes through the center of the structure, and then I clicked angle constraint "explicit reference vector." After watching several youtube videos, I figured that I should click on the work plane, click on another reference point, and then click another point that would be orthogonal to those two (right?). Well after I choose the first point, Inventor will only allow me to choose the center axis as the second option (which I think should be the third option).

I created a sketch on a 'fixed workplane' and extruded it. I would like to know if it is possible to move the workplane? I understand I can change the workplane if it is a 'plane by offset from plane'.
If moving a fixed workplane is possible, does the extruded features move along together?
How does Inventor "Remove fix constraints" so quickly? Can this be replicated in iLogic?
The way I've previously done this requires looping through the constraint collection and deleting one at a time which may take a few minutes on a complex sketch, but when Inventor deletes fixed constraints throught the menu option it does it in a few seconds on the same sketch so Inventor must be able to select them all at once and delete them all at once. Is there a way to do this through the API or iLogic?
I am creating an assembly where I need to add a light probe that is length X from a sensor to an LED. I would like to create a cable modeling this transition to make sure it can be routed around other components. I can't seem to find how to lock the length for the cable from point A to point B, it only changes based on what points I add on its path.

The case is-
1. hollow steel metal ball OD 200mm, ID 190mm
2. Outside surrounding uniform pressure 10 MPa.
3. The ball is floating in a kind of liquid, so the gravity is neglected.
How to run FEA on this ball? How to add fixed constraints.
I've come across this many times now. When in an assembly, I create a sketch. I then try to project geometry and I will sometimes get this error:
"Cannot constrain or dimension reference or fixed geometry."
why I can't project edges/faces/points of certain parts?
The fixed width function did not work when I wanted to draw a fixed width rectangle. Is there a new way to do this in CS6?
View 4 Replies View RelatedI'm sure this has been asked many times but none of the queries I used brought up a similar question. My issue is that I recently spent a lot of time annotating a detail view with leaders attached to geometry, leaders not attached to geometry, and sketches constrained to geometry projected from the view.
I made some modifications to the model which didn't re-locate any of the components that I'd annotated, but somehow the detail view got shifted, and all of my leaders are pointing to the wrong place and the parts of my sketch that weren't constrained to geometry are in the wrong place as well. Some of the leaders seem to have held to their posts better than others, but for the most part my annotations are worthless and will need to be re-done.
I have an assembly which has components mated to a radial surface, I need to locate the center of a round slot against an axis, I have X Y coordinates, how can I constrain that part to those X Y coordinates?
Attached is a picture of the assembly.
I am currently creating a chain block to be animated later on. But, I do not know how to constraint it.
I have attached a zip file of the .ipt and .iam
Maybe I've just been doing it wrong for the last 5 years, but the Angle constraint is obnoxiously unpredictable. When I constrain a part in an assembly with an angle constraint from the assembly origin plane (or anything else), Inventor always has two solutions; a positive and negative.
Is there something I'm missing here, or is just a design flaw we have to live with?
I am trying to place a tubes cylindrical surface to another tubes cylindrical surface using add constraint. How do I specify which side of the target surface to apply the constraint ?
View 4 Replies View RelatedI have a question regarding a transitional constraint between a pin and a surface within an adaptive assembly.
I would like the pin and the surface to be transitional only when the two parts "interfere" with each other.
At the moment with the example attached part A is remaining tangent to part B, restricting the necessary movement of part B to function properly in the mechanism.
In simplified terms I need part B to be able to break free of the "transitional constraint" of part A under certain movement conditions within the mechanism.
This is probably a simple one that I am missing, but how do I get a parallel constraint applied to these two edges.
View 4 Replies View RelatedI have noticed what I consider a bug in AI2009. When trying to delete a coincident constraint using the show constraint command, it is impossible to do so. All other constraints I can delete while I am in the "show constraints" dialog box, but not coincident constraints. As soon as I get out of the "Show constraints" command, the yellow dots are still showing and I can then hover over them and they highlight so I can delete them. Is this how it was intended or should I be able to delete them like the others while still in the "show constraints" command?

I am new to inventor but I would also like to be able to set up my constraints correctly. I'm also not sure if my sketches are ideal for this part either. I usually get an error concerning my fillets from the base to the center support beam when I try to change the 100 to 75.
How do you delete a constraint between a point and the center point of a line? (in the sketch environment)

I have the slide block constrained to slide the distance of the base plate and when I reach the end the bolt continues to rotate when, if this was a real part, should stop. How can I get this bolt to stop once the slide block reaches its ending constraint?
View 2 Replies View RelatedHow do you constrain an object to the origin once the origin constraint has been deleted. I'm not really sure how it became unconstrained in the first place. When I try to constrain the drawing using the coincident constraint it won't allow me to select the origin.
View 1 Replies View RelatedMy need is to assembly parts into an assembly by a known position in the assembly. The part has a UCS and I create UCS on the assembly programatically.

CAssemblyComponentDefinition compDef = doc.get_ComponentDefinition();

To activate the new position of the assembly of approx 5k instances takes about 5 minutes in IV 2013 when using Drive constraint. The larger the assembly the longer it takes
In IV2011 takes about 10 seconds. I've never seen the "Not responding" sign in Drive constraint window in previous versions. I'm just wondering how can avoid this "New feature" of 2013.
We have an interesting problem after reinstalling the software. We found that there is a time lag between the mouse pointer and the line highlight to indicate we have click the correct entity. The video attached in the link below may be able to explain our problem better. In the video, we move the mouse to where we want it and it shows a time lag.

I have an assembly wherein one part is mated to another grounded part, with a face-to-face coincident mate. The click + drag type of movement appears to move the part, while continually solving this constraint.
However, it seems like there is no way to do a rotation in the same manner, where the constraint is continually updated. There appears to only be the "Free Rotate" command, which ignores the constraints.
Is there really no way to do this in Inventor? The application is that I am laying out a mold for many, many small parts, and I am trying to move and rotate them into position to get good packing efficiency and density. Each part will be attached to a mold base with one of the aforementioned face-to-face constraints, then slid & rotated around manually.
This seems like a really important piece of functionality. Solidworks can certainly do this, do a part rotation in an assembly, while solving for existing constraints.
I am using Autodesk Inventor Professional 2013.
Motor Model 1:1 is used to turn the wheel holders at various angles. The part named "front gear spring holder" is supposed to revolve and turn the inner part of the "front wheel holder" My problem is that I want to simulate the turning of the front wheel's using contact sets or 3d/2d contact sets in the dynamic simulation environment. I do not know how to do this, but I'm almost certain the program is capable of doing so. Also the spinning of the front wheels must be able to be done along with various angles of the front wheels(while turning, the front wheels must be able to still spin with the front gear spring holder".
I have seen threads and articles that say that making gears with contact sets is not recommended or possible but i have two instances here where they work perfectly fine using the dynamic simulation with 3d /contact sets. Take a look at the simulation I have saved as well.
I will need more on this assembly in the future, including how to create bevel gears that work at 90 degree angles or spur gears with contact sets instead of just simulating their movements .
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?
