AutoCAD Inventor :: Constrain Component In A Track
Nov 25, 2012
I'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.

I am trying to constrain a curved wheel to a round, steel track. No constraint has been effective so far. Is there anything I can do to make the wheels stay on track?

I'm trying to constrain the green cylinder to move between the red frame. The red cylinder is constrained on the surface of the larger gray cylinder, which moves around the grounded red frame. When the green cylinder goes up hill/down hill the larger gray cylinder is supposed to rotate around its own axis.
When I choose transitional constraint I'm only able to pick one face on the red frame, and not the whole face. I think it's because the face is not planar, but varies in z-led.
Neither am I able to use the Contact Solver, it seems like the friction is too high. The green cylinder doesn't slide that well when using Contact Solver.

We are having an issue when we replace a component in Inventor Pro 2012. When we replace a component, the name in the browser does not update to the new component. We've even tried to close and re-open the Inventor assembly and that does not work. We end up manual double clicking the name in the browser and type in the new component name.

II need a way to tell if a component occurence is a virtual component.
I'm using a For Each loop to cycle through all of the components in an assembly, and if the component is itself an assembly to set the LOD to "Custom". I'm using the definition document descriptor object for this. It all woks fine until the loop comes across a virtual component which doesn't have a definition document, so I need a way to check if the component is virtual and needs to be skipped.Here's the
Option ExplicitImports Inventor.LevelOfDetailEnumSub MainiLogicVb.UpdateWhenDone = TrueDim doc As AssemblyDocumentDim oLOD As LevelOfDetailRepresentationDim oAsmCompDef As ComponentDefinitionDim oComp As ComponentOccurrenceDim oComps As ComponentOccurrencesdoc = ThisDoc.DocumentIf.

I am trying to make port rims for pipes that can be swapped in and out of an assembly. However, the ports will all be different sizes and located differently so I need the cut to be part of the port rim component, but affect the entire assembly it is part of. I've been trying to get this to work for the better part of a day now,Here's a picture of what im talking about. I'm running Inventor 2008 by the way.

I have an assembly which has a few components suppressed.
My end results is another copy of the assembly (with copies of the all the parts) in another directory
Now i am able to create copies of un-suppressed parts using; (this allows me to SaveAs assembly components which are not suppressed)
DocumentsEnumerator = ThisDoc.Document.AllReferencedDocuments
And save a copy of the assembly using
ThisDoc.Document.SaveAs
I also added the fllowing snippet (which I am not sure what is does), but it does not work for me
Component.SkipDocumentSave = true
When I open the newly created assembly, I still see the suppressed components in the model browser
I want to either;
Skip saving the of the components in the model browser (i.e. the Assembly)
OR
Delete the suppressed parts in the Assembly, so that they do not save altogether

I'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.
Public Sub DrawSketchLine() ' Check to make sure a sketch is open. If Not TypeOf ThisApplication.ActiveEditObject Is PlanarSketch Then MsgBox "A sketch must be active." Exit Sub End If ' Set a reference to the active sketch. Dim oSketch As PlanarSketch Set oSketch = ThisApplication.ActiveEditObject ' Set a reference to the transient geometry collection.

I've made 2 parts and I'm attempting to constrain them but I can't seem to get it to fit properly.The transition should fit at the opposite end of the 2 square cutouts with the square end of the transition inside the cylinder.

I am trying to CAD a model rocket I just made so I can test the aerodynamics of it. I have all of the individual parts made in inventor, but I am having trouble getting the fins on the rocket.
How can I constrain the fins (which have a flat face) to the outside of the cylindrical rocket tube? The photo shows the fin and the face (the narrow and long face) that I am trying to constrain to the tube.

SO 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?

I 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...

I 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

How is this accomplished in Inventor? The 3D sketch environment seems intentionally crippled. Many of the constrains are not available, and the "include geometery" command refuses to include the origin (or any other planes and axis for that matter).

What is the difference between Constrain and Assemble?
They both seem to create the same mating constraints, but Assemble doesn't work with adaptive parts.
Any other difference (other than the interface)?

Is 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.

I 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.

I have an assembly with a curved line made in a sketch, and a part with a point in the bottom.
I want to constrain the point to the curved line, but the regular Constrain options wont let me do so.
I am making an animation with Inventor Studio, so I need this constrain, so I later on in studio can manipulate it and insert the first part into the other.

How you constrain a section view so that is perpendicular to an axis. See "SECTION B" on the attached drawing for an example of what I am attempting. I have created the view but cannot make (constrain) the view perpendicular to the slot that is orientated at 30 degrees from the vertical centre line. I have lined up the view by eye so it looks close but it's obviously it's not accurate.

After installing the cloud-optimization-upgrade for subscription customers I cant export video from "drive constraint".I click the "record" button, I choose the name and quality of the video and when i then return to the "drive constraint dialog box" I get an error message "The file constraint.wmv could not be opened".
I have tried different names, storage locations and different video-quality but nothing changes.I successfully performed the same video creation just before the upgrade with the same assembly file so I know that its not the file.

Lets 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.

For some reason it will not let me constrain a part to the center of gravity plains. I would like to constrain lifting lugs to the center of gravity so the model will automatically update itself. Is there anyway to make this work (using ilogic or anything)?
Why would Inventor tease me with showing me the center of gravity plains in an assembly but making them completely useless?

I'm currently using Inventor 2013. but I've seen this in earlier versions of Inventor.
After creating a view within a drawing sheet, if you RMB on the view label, an option for Constrain to View Border appears.
What does this option do and how is it used? I don't see anything happening when I use this option.

I'd like to constrain about 100 parts at the same time to the same plane. They are the same part, copied over and over.
Is there any way to do this quickly? A component pattern is not an option in this situation as the spacing is very irregular.

I'm a playground designer and we're currently in the process of updating our systems to Inventor. Over the next few years I'm going to be working on many different assemblies all using the same parts and sub assemblies, many of which need to share the same ground plane.
I'm wondering if there is any easy/quick way to make certain parts (not all) automatically constrain/flush to the ground/XZ plane when I place them?
