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.
I need to drive more than one constraint at a time. The assembly consist of a hydraulic ram that pulls a cable which is routed around a few pullys and then pulls another linear moving member. I don't really care about modeling the cable right now, I just want the cylinder piston and the final member to move in unison. I can only drive one constraint at a time, so I figured I could relate the two constraints together by setting them equal to a parameter (variable), but that isn't working. Is it me or is driving multiple constraints at a time something that would be very useful for a lot of applications?
View 3 Replies View RelatedI'm modeling cables running through a series of cable clamps. I'm working in an assembly with my structure as one part, clamps as seperate parts, and cables as separate parts. I modeled the clamps first and am using them to create my 3d spline to run the sweep. The clamps have moved several times and each time, the sweeps (cables) do not update to follow the new clamping path. I have tried multiple ways of solving this.
I've tried to redo the splines using "Include Geometry" and running the spline through the centers of the clamps. I've also deleted the constraints (which for some reason turn into fixed) and reapplied them as coincident constraints. However, once I setup these coincidences, they always change back to fixed.
In a last ditch method, I've created 2d sketches at EVERY clamping location (yes that's alot of sketches, time and effort) and projected the circular geometry to get a center point. This has seemed to work, but is so much work, there's no way we could use it regularly.
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.

And try to extrude the sketch it extrudes but only in cut mode it is the only button that is working the rest are all faded out.
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)?
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.
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.
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.
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?

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.
I am trying to assemble an extruded tube that has holes drilled, to a flat plate to be bolted together. when i go to assemble the parts the drilled holes will not highlight to attach the plate to.
View 9 Replies View RelatedI 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.

Is it possible to assign a project number to a project file and have it fill in the project Iproerties field?
View 2 Replies View RelatedI do not have vault installed and I am trying to add sub files to my project. As of now my project has to find many of my files and I do not want to copy and past them into my project folder as this will mess with my parts numbering system. I want only one part / assembly file per part. I assume that you can do this with the project dialog box or some other system tool I just can not seem to figure it out.
View 1 Replies View RelatedWhy do we not have the "=" (equals) constraint option in 3D Sketch mode? It seems like a very basic need for a constraint. Is there a reason why one should NOT want to have an "equal" constraint in a 3D Sketch?
View 3 Replies View RelatedAll I need to do for now is to align one part to the center axis of another part. Later I will constrain but for now I just need to see where the two meet so I can project geometry onto a draw surface. So, all I need to do is make their central axes coincide on one straight line.
I can achieve the same result by counting the various lengths but I'm hoping there's a simpler solution.
Assume a beam like the one in the picture below.
How must I configure the constraints?
The left constraints should be a "Fix constraint" on the edge(not the face) I assume.
But the right constraints must not fix all DOF's.
How can I configure the right constraint?
I've just installed 2012 and I seem to have a problem with constraints.
The basic problem is that the SHOW CONSTRAINTS command doesn't show the constraints for geometry that clearly has them. For example, if you delete a horizontal constraint from a line and then add a horizontal constraint to the same line, the line will be constrained but the constraint will not show up.
is it possible to copy and paste parts in an assembly but also keeping any constraints set on the part?
I.e. if I had a square block constrained to a flat face of a floor, when I copy and paste the block many times I would like all the copy blocks to still be constrained to the floor.
Is there a way to get a list of constraints that exist between two parts in an assembly?
It will take forever to go through each and every constraint for one of the parts, checking the "Other Half" of each just to find all constraints between to specific parts.
I'm trying to build a c# program where I can test a simulation for a robot project I have made angle constraints in inventor and now I want to be able to send numbers to specific joint.
With the code listed below I can get all the constraints from a selected part and get the name of the specific constraints.
I find it confusing that most of the documentation is in VB so this is what I have discovered on my own, perhaps this isn't at all the way to do it.

Trying to create a gimbal with a supporting frame, an outer square frame, and an inner square frame. when i insert the outer square frame into the supporting frame, i constrain it so that the axis of the hole i have drilled in my frame and the axis of the hole through my supporting frame are aligned, i then constrain a face of it to be a set distance from a parralel face of the supporting frame to centralise it. this works ok, and i can rotate this frame as i like. When, however i insert the inner frame and constrain the axes of the holes drilled through it to the axes of the other holes drilled through the outer frame, and two faces to be a set distance apart, it allows me to rotate my inner frame, but no longer allows me to rotate my outer frame! what have i over-constrained?
View 3 Replies View RelatedI'm using the line tool in a 2d sketch. First, I draw a polygon with the tool. Then, when I come to move one of the lines with the mouse cursor, it detaches from the other lines, and becomes a single floating line on its own.
As far as I can tell, it has nothing to do with the fly down constraint menu options, but i may have changed another option elsewhere in inventor and not have realised it.
Using "drive constraint" I would like to simulate the action of a "soft close" mechanisim on a drawer...fast movement for the first portion of travel, then slow movement for the very last portion of travel...

The refresh button isn't "lighting up", or when it does, it does not do anything to move the rail. Is there something that's been "shut off" to keep things from moving?

I've attached a file showing what the problem is, please don't judge the model tree. I was prototyping as I went so it is messy.
Out of the blue, my IV 2012 has decided to stop showing the preview when applying contraints. I have made no changes to any options or configurations. Preview check box is checked.
I tried unchecking and rechecking it to no avail. Any thoughts on this behavior ?
2nd out of the blue issue - when I insert a part into my assy (part file is in the same folder where the assy file is located) IV decides it needs to create a sub-folder and re-saves that part to the sub-folder. I mean, WTF ? The part file is already there. Why create another version of the part in a sub-folder. And why would it just start to do this out of the blue.
Again, I have made no changes to any configurations, options, settings, templates, etc...
Why is it when I select multiple contraints for a component that I can use the delete key on the keyboard to eliminate them but when I select only a single constraint, I have to right click and select delete on the context menu. The delete key will not work on a single constraint.
