In my line of work, the constraints are fantastic. I do use them a lot for the design and drafting.But, somehow, they are slightly buggy. I wanted to know if there is something I can do to make them better.The problems are:
1- Sometimes I can't add a constraint that I KNOW will not overconstraint and that CAN be added. This happens for all the constraints types. For example, sometimes I have one big block with the plot plan of the factory and I want to make a constraint of one other smaller block (an equipment, for example). The constraint is a simple coincident. The plotplan has several objects constrained to it (blocks, lines, etc.) but the smaller equipment block has no constraint whatsoever. Why doesn't it work?
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.
I've recently upgraded from AC 2007 on Windows to AC 2013 for MAC. I like all the improvements except for constraints pop up that comes after I make a line or polyline. I have figured out how to temporarily delete them by using DELCONSTRAINT but once I make a new line they return. I would like to permanently turn off the constraints but have not figured out how.
Just upgraded to 2013 about a week ago. Random part files seem to be giving me the same error message "A cyclical constraint dependency has been detected." Some of these parts are ones that worked fine in 2012 and some are ones that I created in 2013 and worked fine for a while, but then started giving me the error later on.
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).
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?
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?
Coincident Constraint to be offset? I'm trying to constrain a table and a MTEXT object together but they are "mating" at their Insertion Points. I cannot successfully "move" these two points, keeping them constrained.
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 ?
I 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.
1. I created a schema in SQLite witth AutoCAD Map 3D 2012.
2. I set a constraint to one field: a list with 3 entries valid for the property. For example: Test 1 Test 2 Test 3
3. I draw some lines
In the schema editor I want to change the constraint:
- But I am not able to add a new entry “Test 4” to the list from step 2
- I am also not able to change an existing entries (“test 1” to “test 1 new”)
Is it possible to change the settings of a constraint?
The help [URL] says: “You cannot edit a schema to convert an existing field to use a different constraint type if the table already contains data. The table must be empty.” But I do not want to change the “constraint type”. I want to change the entries of the list.
I 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?
Is there a way to expand the constraint window so that I can see my entire parameter formula? In the image below, my equation is cut off in the "offset" window. Or am I supposed to be inputting the parameters in some other manner?
I'm having a really difficult time maintaining my parameters when making changes to the part I've made in the attachment. The control parameters for this part are:
-100 mm distance between 15mm circles -1 of the 15 mm holes -30 mm hole
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.
I'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?
How 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.
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.
My 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):
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.
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?
