AutoCAD Inventor :: Motion From Cable And Pulley / Constraints Without Contact
Aug 10, 2013
I am trying to constrain motion for the following design:
-Object constrained to vertical motion (a counterweight).
-Object constrained to horizontal motion along a track (a slider).
A cable runs from the counterweight upward, makes a 180-degree turn around a pulley, runs back down, makes a 90-degree turn around another pulley, and connects to the slider.
When the weight moves down 10 cm, the slider needs to move laterally 10 cm.I don't care about modelling the cable, but I do need to have the slider move as the weight moves.
I will also need to model a case with a more complicated pulley, where when the weight moves down 10cm the slider moves laterally 5cm (again I don't care about the cable, just the relative motion).
Is there a way I can do this without creating a series of planes and cylinders and using rotation - translation constraints to link the motion of the weight to the slider?
Can 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'm trying to run a simulation of 2 bevel gears without using the transitional/rotation constraint, but using the contact between the surfaces to simulate the rotation of the gears - basically I have an L-shaped shaft running through both centers and want to have the upper gear grounded, make the lateral gear rotate around its own axis - the goal is simply to see the contact between the gears make the side gear rotate around the vertical part of the l-shaped shaft, due to the contact forces.
I am pretty familiar with Assembly constraints but I want to know how do you constrain/motion a screw or similar object to be able to turn appropriately whilst going up & down a threaded hole?
I am working on a assembly where a cable wrapped around a drum is animated to rotate with the drum, and there is a longer cable coming off of the rotating cable wrap, this longer piece goes down to another cable on a roller assembly. I have edited the assembly to work without the actual cable drum and without the roller assembly ( I wasnt allowed to share those models ) There are now two cylinders in place of the cable drum, a Grounded center to hold everything in place, a Rotating center which is animated so the wrap can rotate.
My problem is when the part named "Drum to Roller" is a lofted cable with angled ends to meet the "Drum wire wrap" at one end and it meets the "Radius cable ends" at the other end. I need the "Drum to roller" to stay constrained to the "radius cable ends" as well as the "drum wire wrap" ... and after being constrained still animate.
I have set up the animation and you will see that the "Drum wire wrap" is animated to keep the end vertical , the animation is set up to look like the "drum wire wrap' is un-raveling cable and the "drum to roller" is to be what un ravels.
I need to find a way so that the "drum to roller" translates down and over , staying constrained to the "drum wire wrap".. You will see that so far it does not.
I have attached two links below they include the two halfs of my assembly, place all the files in the same folder so you wont have to search for them manually.
I'd like to make an animation of a thin copper wire being wound onto a pulley. Is this possible in Inventor? I'm not sure Inventor will allow the thin wire to be bent. I can imagine other ways to make the animation, but I'd much rather have the wire bend around the pulley as the pulley rotates.
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?
I'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 work for a company that does custom electrical enclosures and we use a 2010 version of inventor professional. What would be required to run wire in assemblies easily and also output wiring diagrams?
I have these cable segments in my models. The problem I have is that when I render them or zoom out all of the work points and segment points become visible. It's only when zoomed in that they disappear.Look at the attached images for an example.I would really like my rendered videos to not have bright yellow spots.
I have created a cable/harness in my assembly. I have to edit the cable to change visability to centerline display in order to turn off visibility in a drawing view. The issue is that on one sheet of my drawing I need to show the cable, but not on the others. As soon as I turn the rendered display on, the cable shows up on all sheets and the visiblity command has no affect. Is there a hotfix for this? I don't remember a problem like this in 2011.
I would like to include Terminals and other virtual parts in het BOM on my drawing. For this I need to generate a report. I have defined my own virtual parts but somhow their properties are not accessible. You can see 88 items but this is the total of all segements and pins. Somehow partnumbers show as "---". I have included the report configuration file I am using.
When I try to create a custom ribbon cable I get a message that reads:
"The cable and harness library is being edited by another user or is marked as read only. The Cable and Harness Library will be opened in read-only mode. No changes can be made to the cable and harness library, but wires and cables can still be inserted into the harness assembly."
In my project file I made "use style library" to = Read-Write

I have a bit of problem that've been cracking my head. I create a wires, segments using cable harness environments in Inventor. After I created those, I want to see rendered image, but only centerlines appears. I have already change the harness settings into real image(rendered) but still centerlines appears.
Weird thing is that I create other assembly, it all works perfectly. But I cannot recreate my design, it is already so much work.
How do I ad my own terminals, seals etc. under Connecter Pin Propertiesvirtual parts, and how do get this information on the nailboard.
Alternatively, I would to put this information(seals and terminals that are to be used with the connector) directly on the connector that i publish to content center, some sort of property/text, that I can retrieve on the drawing/nailboard.
I am trying to create a ribbon cable between two connectors, but for some reason the ribbon cable starts away from the connector and I am not sure why?
I was wondering the best way to model a steel tensioner cable in Inventor. The assembly I have designed is of a cable fixed between two brackets which are fastened on two structural beams. I am looking accurately model the cable attachment on the brackets. My inital thought would be to extrude the length of cable through a pre-defined path between the bracket fixing holes however this would not represent a 'true life scenario'.
I am working on a model that uses a few lanyards to attach some pins to a plate. For the cable in the lanyard I used the cable and harness to create an assembly from segments. I just now need to know how to change the color of the wire from blue to green and also how to remove the yellow outline. I want to use the images in a manual so I want them to look correct.
I have an assembly that I want to put some wires in, but every time I create a wire between pins, or a segment, or anything through the Cable and Harness tool, the centerlines don't show up. The rendered wires can appear, but without any sort of way to get at the centerline, I can't set its path or anything like that.
I was wiring up components no problem in a sub assembly, but for some reason it just won't work in my top level assembly. I thought it might be a problem with how I added pins to the components, but even trying to create a wire between 2 connectors from the content center gave the exact same results.
It is a while ago since I used Inventor, so i'm now just practising a bit to get the hang of it.
As a start a cable stayed bridge looked fun. So I made the towers and the roaddeck. But now comes the tricky part, and that are the cables themselves. When I started I just thought I could use the 3D sketsh feature. But as it turns out, that feature is not available in the Assembley environment. I could just make the cables as a Part and then insert them in the assembley, but that is to much work. As you can see from the pictures below the holes I made in the towers to accomodate the cables do not line up with the edge of the roaddeck on which I want to secure them. So the cables make to much angles for me to make the as a part. And besides that, I just think it could be done more easily.
Below you can see the images I made of the bridge so far. The first one is an overall image, the second one shows the tower with the holes (if the holes won't work, I can always make something else), and the third image shows the area on which the cables will be attached to the roaddeck.
Can this be done in the Assembley environment?
Note: I planned this to be a cable stayed bridge, not a suspension bridge. But tips to make this into a susension bridge are welcome as well.
I have a client that is trying to use the Cable and Harness feature, but receives the following error:
"The Cable & Harness template was not found. The specified location for the project is: [C:Workspace|Design DataCable & Harness|en-US] Please verify that the template file exists.
He has Inventor installed on his D drive, along with most of his other programs. OS, etc are on the C drive. I have verified that he has harness.iam and a Cable&HarnessDefaultLibrary.iwl in the following location for Inventor 2013

Am looking for the feasibility to check space available in Segment.I've assigned a segment diameter as 2 mm, and i have 2 wires have .9 mm dia each, Now i want to know what will be the remaining space available in the segment.
in another way around, if am adding more wires in the segment will inventor give any error message stating that there is no space for route more wires in that segment,
When I try the generate a report within Cable & Harness the button stays depressed and no window pops up. I have tried to generate the report on 2 other stations with the same result.
I am trying to make a model of coil cord cable (looks like phone cable) in the autodesk inventor10. I know to make a model of the coil cord when it is straight, but how can i make the coil cord model when it is folder.
Im trying to figure out if Inventor's dynamic simulation can simulate gravity on rope or cable shaped solids.
I have a power cord design that I want to display with its cords in various natural positions (IE Flat on a table, hanging from a wall, etc). (see image attached)
My questions are as follows:
1. Can dynamic simulation simulate a rope/cable type object falling with gravity to a natural hanging position?
2. If it can, can I also then save the resulting new shape/model and export it to showcase for rendering (or render within Inventor)?
3. I am currently creating the cords using the sweep command. Using this seems like it may cause problems for the simulation. If I use the wiring harness design part of inventor to create the power cables can it then simulate the cables naturally falling and resting due to the forces of gravity? I know the wiring harness design area is built in, but I have never even opened it before..
Many times, we run several individual wires from one device to another. They are not grouped in a cable jacket or anything just individual wires. I was wondering if there is anyway to make the wire routing look a little neater as right now I have to tweak each wire one by one and many times it looks like crap. Can I use a segment for this and then just turn off the visibility of the segment or something? I just want the wires to look neat running from one place to another and there must be a way to do this?
I've been creating documentation for cable assembly for many years now and I am trying to determine a way to use the Inventor Cable and Harness feature to accomplish the same detailed drawings as I previously made by hand. The first thing I notice is that the connectors do not exist at the cable level, even though this is how they will be manufactured. Is there any way to generate a cable with wiring and connectors all existing together in an assembly that can then be documented in a drawing?
