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 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).

The ladder design is such that the base brackets are fixed to the ground and the rest of the ladder may move about the axis of the bolted connection at the base of the ladder. I cannot get the angle constraint on the ladder to allow this.

In my assembly I've set up angle constraints between 2 Plane's of 2 parts (min: 40 deg max: 160 deg). If I move the parts slowly the angle constraints holds but if I swing it hard sometimes it flips and gets out of the angle constraint.
View 2 Replies View RelatedI got a problem with editing angle constraint in assemblies. I tried edit property of constraint but it didn't move model. Simply changing Angle attribute of constraint item don't work.
Only way I achieved movemenet is
if(oOccurrence.Constraints[i].Name.Equals(name))
{
AngleConstraint a = (AngleConstraint)oOccurrence.Constraints[i];
Object oEntity1 = a.EntityOne;
Object oEntity2 = a.EntityTwo;
String sVal = "" + angle + " deg";
[Code]...
but this is really slow, as much as changing throught parameter:
if (assemblyDoc.ComponentDefinition.Parameters[i].Name == "d655")
{
Inventor.Parameter invParam = assemblyDoc.ComponentDefinition.Parameters[i];
invParam.Value = Math.PI * angle/180;
inventorApplication.ActiveDocument.Update();
}
I have used a driven contraint in a sketch.
Can that also be done in an assembly?
In one assembly I want to make one angle half of a driven angle.
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?

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)
View 2 Replies View RelatedI've assembled a bolt and a slide block that is constrained to a base plate and am able to put everything in motion. 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 9 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. What I cannot do is to constrain the two UCS. I tried this (Inventor 2013 x64 on W7/W8 64, c++ 2010 by the way DEBUG mode is not working from the IDE):
CAssemblyComponentDefinition compDef = doc.get_ComponentDefinition();

Set oPartAxis = oPartOcc.Definition.WorkAxes.Item(3)

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 can't seem to get inventor to select a given parameter inside a sketch. It keeps giving me an error.
All I want to do is to have inventor Select / Highlight a parameter inside of a sketch so the user can clearly see it in the window. Ive tried heaps of different selection options, I just can't work out what ive done wrong.

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?
I want to create some universal bricks creations. These bricks have studs which fit into another brick. To constraint them I need to do following actions:
- click place constraint
- Assembly >> Insert >> opposed
- Offset 0,35mm.
I would like to make above into 1 action, so just click to add this action, then select the 2 faces to constrain.
I have been getting this error message alot with 2013. I never got this before with previous versions. I do alot of assemblies that are made of parts that are derived from a main sketch part. The only way to remove the error is by deleting the right part out of the assembly and I can procede. I have read that it has something to do with renaming parts, but I still dont completely understand how I am getting this error. My work flow is the same.

It would be a nice feature to have a control panel in Inventor where you could take certain driven constraints and put them on this control than hit a momentary button to make your model move. Once example would be a hydraulic cylinder. Presently, we drive the cylinder to put things into motion, but I have to access thru browser and usually add symbols to make the constraint stand out (See image). If I had a control panel where I could tie that driven constrain to it and depress a toggle/button which would activate the constrain. I would then have full control and almost act like it would in the real world.
