AutoCAD Inventor :: Difference Between Constrain And Assemble?

Jan 10, 2012

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)?

AutoCAD Inventor :: Create Parts Then Assemble Them?

May 15, 2013

I was wondering if you create the parts then assemble them.  Or can you create and assembly then break out the parts?  I am just testing inventor out to see if it would be good for my company.

AutoCAD Inventor :: Constraints To Assemble Project

Feb 10, 2012

Something is strange with the constraint activity.

I'm using the constraints to assemble a project. I select the parts with the proper constraint, when "apply" is clicked the parts do not "pop" to location as they use to. I have to go up to "manage" the click "rebuild all" for the parts to move to new location.

AutoCAD Inventor :: How To Draft And Assemble Parts

Oct 14, 2013

I went through a bunch of tutorials on how to draft and assemble parts and when going through them step by step everything looks really neat and works well.  Start with blank files and try creating something from scratch and that is when the laws of the universe no longer apply.

I am sure I am doing something wrong here but the problem is when logic and common sense no longer apply and each mouse click and drag is bound by some law that cannot be documented let alone repeated that is when I start getting lost.

My assembly is mainly comprised of pipes, clamps and pipe T-joints which are joined by rotational joints.  I am sure this has to be a tricky assembly task since I have witnessed numerous times my assembly flying apart in every possible direction into a tangled mess from just trying to nudge one part.

For example -> Currently I have a part bound by a single rotational joint and I ground the pipe this joint is connected to.  I have used this many times now to rotate parts relative to one another to prevent the arbitrary explode and re-arrange that occurs if you do not ground a part.  Now all of a sudden when I try to rotate this part I get a circle with a cross through it beside the mouse pointer telling me that this will not happen.  Why now?  For a sanity check I went back to a previously saved file and the same scenario works.  Why?

The best part of this software is the: "The assembly cannot be solved" dialog that pops up as soon as anything gets more complex than a single joint.  This dialog fascinates me since after it pops up and I cancel it I will spend a half hour trying to ground parts and nudge the pieces closer together.  Then I try the exact same joint and...... it WORKS!  It blows my mind every time.  So is there a internal timer that ensures you spend an appropriate amount of time screwing around before it will let you pass to the next level?  If I can ground/nudge the two pieces I want to join in about a half hour why can't the software do this, maybe I am missing something but I thought this was the point for software like Inventor?

How I would try manipulate it if it was in front of me.  I see a part that needs to be rotated so I try click and drag it into place, of course Inventor has no clue that the part I click on could possibly be the one I want to move so every piece not grounded will fly off into random directions.

AutoCAD Inventor :: How To Assemble A Manufactured Pipe Nozzle

Oct 8, 2012

I am struggling with a relatively simple exercise in inventor. I would like to assemble two pipe segments intersecting one another to form a pressure part nozzle, as shown below:

I cannot seem to find a relatively easy method of doing this. I've tried pipe & tube routing but it doesn't seem to have this functionality. Apart from actually modeling the nozzle to have the contour shown above, how would one achieve this easily?

Pipe & tube routing allows one to align these two segments of pipe, but it doesn't contour the nozzle pipe segment to the circumference of the pressure part segment.

AutoCAD Inventor :: Assemble Components In Circular Pattern?

Sep 25, 2012

I want to arrange these outer circles in a corcular pattern at equal distance and at equal angle from each other without using circular patten feature in assembly tab. How do I do that.

The reasomn I dont want to use circular pattern in assembly tab is if I do that then, I cannot change color of each outer circle separatly If I change one color it changes color for all of these whcih i dont want.

I want to have each outer circle of different color.

AutoCAD Inventor :: Assemble Two Parts Together By Constraint Feature

Nov 17, 2011

I am trying to assemble two parts together by the constraint feature, but the problem is that I mirrored one of the parts to make the other and now that I am trying to assemble them together they both light up showing that they are the same part.  I am trying to make them to individual parts so that I can assemble them. Can I fix it in the Assembly  or Part drawing?

AutoCAD Inventor :: Assemble Multiple Leds On Matrix

Sep 26, 2012

I am assembling multiples leds on a matrix that I made.

Is there any way to make the assembly using constrains to place the ipt LED design on the matrix without placing one by one?

The constrain I am using for each led is Insert.

There got to be a way to insert the leds directly, like when you are placing screws and it detects all holes and places the necessary number os screws on the existing holes.

AutoCAD Inventor :: How To Assemble Fasteners To All Holes Created In Single Hole Feature

Jan 18, 2012

I have a part with multiple holes created in a single hole feature (i.e. not patterned but made by selecting multiple sketch center points).  As desired, the holes all have the same size since they all fit the same fastener.  Is there a way to easily assemble fasteners to all the holes?  Currently, I am using insert for each fastener and this gets tedius if there are many holes.  Additinally, if the number of holes changes, a manual update is required.  I'm hoping there is something that works similar to associative patterns.

AutoCAD Inventor :: Using VBA To Constrain A Sketch

Jun 26, 2012

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.

AutoCAD Inventor :: Speeding Up Constrain Execution

Oct 19, 2012

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?

AutoCAD Inventor :: Stress Analysis / How To Constrain

Dec 31, 2012

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...

AutoCAD Inventor :: How To Constrain Movement In Slot

Jan 9, 2013

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

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.

AutoCAD Inventor :: Constrain To Origin In 3D Sketch

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).

AutoCAD Inventor :: Tangent Constrain On Multiple Curves

Aug 4, 2013

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.

AutoCAD Inventor :: Sketch Changes Constrain Status After Rebuild

Oct 22, 2012

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.

AutoCAD Inventor :: Constrain Point To Curved Line?

Nov 23, 2012

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.

AutoCAD Inventor :: VBA Script To Constrain Multiple Parts

Jun 28, 2013

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.
