Assemble several parts from Solidworks through step profile.Part2 and part3(attachments) no static interference ,when driving constraints (driver) immediately a collision report appears.Additional,when restrain the part 3(attachments)and drive constraint(driver) meanwhile open the collision detection ,finally,part2(attachments) goes through the barrier no checking collision.
View 9 RepliesHow do you mate two surfaces so that the item will not move any further once it makes contact with that surface? i.e a rotating cam which is designed to stop once it comes into contact with an object / surface.
View 2 Replies View RelatedI 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 9 Replies View RelatedCan an adaptive part (non involved in the drive constraint animation) bother the contact solver?
I have an assembly, with only one adaptive part, i have activate contact set for other 3 parts (not the adaptive part), activated contact solver and drive the constraints, but in the animation contact solver doesn't work at all.
So, i have tried to move manually the assembly (suppressing angular drive constraint) and the contact solver works fine.If i suppress the adaptive part the driving constraint and contact solver work perfect.
So i wonder... adaptive part can annoying the contact solver functionality?
I tried to report my dimensional constraints in my drawing as a table. Is it possible?
View 0 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 have some model boat plans (scanned images) and would like to convert them to 3D objects. I used a software img2cad for the conversion, and since the conversion is not perfect i have to redraw all the parts. So here are my questions:
1. For the parts i mostly used lines, splines and arc. What is the best way to join them, so later i can edit them to 3d solid object? I used join and it works well, however it creates a small angled edge at the end. (see image or zoom in dwg file).
2. For some of the parts the extrude command works only on the edges of the 2D object creating a hollow 3D object. How do i fill the inside?
3. In near future i would need to assemble all the parts and make the skeleton of the boat. Is there a way to check for object collision (if parts are too big for example to fit where they should)?
I also attached a file with two ribs of the boat as an example.
Is there any way in standard inventor to find what sketch is related to a frame generator member?
View 6 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?
When defining a wire, to get the correct termination at each end I would like to add Virtual Parts to the Connector Pin Name properties (Select the with, RMB - Harness Properties- From To- Properties (connector Pin Name)- Virtual Parts.
Is there any way to get properties from this onto a Loom Report allied to the wire? Our current Loom drawings list the wire with the terminal connectors at either end. I have tried using GETPART1 & GETPART2 in the cfg definition but this picks up on the Part with the Pin, not the Virtual Part on the wire.
I have an assembly already created with weld bead on it, at the moment I click on creating a weld bead report, it asks me to include all assemblies, I selected the option, and next it opens a window to save the spreadsheet, select the destiny, and next it says that no weld beads were found! report will not be generated.
View 5 Replies View RelatedI'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.
I have some "insert" constraints for DIN rails in holes. I've moved the holes, but the DIN rail doesn't move. 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'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.
Does Inventor (2012) have the option to view sketch constraints as a list? I feel like I am playing pictionary trying to find out what constraint is what and what it is constraining and it doesn't work that Inventor stacks anything nearby on top of each other.
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.
View 7 Replies View Relatedthe .iam assembly and the .ipt parts are to follow.I'm not very concerned with the teeth meshing properly at this stage. I just want to get the rotational constraints correct first. There are two situations that I am trying to work out, and I think I took care of the first one.
Situation 1: Blue carrier is grounded.
Input: Rotate purple sun gear.
Result: red planets turn the orange planets which turn the green sun(green sun to purple sun ratio = 1:1 but in the opposite direction)
Situation 2: Purple sun is grounded (Blue carrier is released)
Input: rotate the blue carrier
Result: I want the planets to still be able to rotate, and basically be driven by the purple sun which is being held. This should then drive the green sun to rotate in the same direction as the blue carrier gears.
The issue here is clearly that the red planets will not rotate since the purple sun is grounded. What should the constraints be instead of a simple rotational motion constraint? In a perfect world, I would like to not have to ground the purple sun, and only have the purple sun rotate when I specifically rotate it. The main input to this system is rotating the blue carrier gear. The purple sun is simply a control/variant.
I am working on an Inventor Studio animation and have noticed a problem. It appears that it is not possible to suppress/enable translational constraints. My assembly has a translational constraint that I suppressed in order to “explode” the assembly. I am animating the assembly process. Once it is put back together, I need to enable the suppressed translational constraint in order for the model to function properly.
I thought about recording two animations and then splicing the two videos together, but I am worried about the transition. I really need it to be a smooth transition in order to work.
I have some geometries that are patterned in a sketch. Turns out that i don't want a pattern anymore but i have a load of stuff that is dependent on some of the patterned lines. So i show all constraints and you can see the little rectangular pattern constraint icon. but you can't delete it like you can with other constraints.
The reasoning behind this is logical, but surely i should be able to break the link of a pattern and then re constrain the geometries how i see fit, that way i maintain all of my associations and my other features won't fail due to a lost link. See attached pic, i want to change one of the vertical lines so it now sits at an angle.
Am guessing inventor does not allow getting the constraints when you mirror a part..but is there a work around or easy way to copy the constraints.
