AutoCAD Inventor :: Create Rotating Pulleys With Belt Can Be V-belt Or Synchronous One
Jan 2, 2013
I need to create rotating pulleys with belt can be v-belt or synchronous one. Shaft number one needs to power shaft number two by using this belt. I created shafts and belt with pulleys by using design accelerator but I dont know how to set all the constraints/connections to make them move. Link to the animation tutorial( I found tutorials for this but they are not with the shafts, just pulleys with chain or belts).
How can I create a flat belt driven system? The drive system and the flat belt are in the attachments of this message.
What I did until now was to create a part for the belt within the assembly (extrude part). The sketch is depending on the position of the rollers and everything else. Although when I create the belt I can no longer move the system. If I suppress the belt, move the system and unsupress the belt, the belts assumes the new positions.
My purpose would be to be able to still get a variable assembly so I could also make a dynamic simulation of the system.
Is there a way I can add hpt belts to the design accelerator? I'm using inventor 2013 and I want to use 8m belts without having to find the models of each pulley and individually add them.
I am trying to simulate the path of ropes through pulleys/sheaves etc. It's a bit of a chicken-and-egg set up.
My workflow is the following:
Assemble and constrain geometry
Create plane in assembly than rope will run on.
Create in-place part (rope) with box ticked for "constrain to sketch plane" or the like, referencing above geometry.
Question 1: I see my in-place component is not constrained to referenced geometry, I can drag it around?
I then ground it or constrain to workpoints used as part of the original "project geometry".
I then alter the original geometry and...nothing!
Question 2: How do I get my rope to adapt?
Attached is a mock up - original contains assemblies within assemblies etc. The base has been altered after creating the in-place parts, and the rope has not followed suite.
I have a solid body .ipt that I have created an assembly from. Some of the parts in the solid body can rotate which in turn rotates them in the assembly which is great. The problem is I need to create a drawing of the parts of the assembly. If I create a base view of a part that rotates the view rotates also, but I do not want that. Is there a way to create a view that always "looks" at a surface of a part no matter what position it is in?
I am fairly new at animation. If I want to simply create an animation of an assembly just simply rotating in 3D space which I then can import in Showcase for a presentation, how would I do this in Inventor?
I've tried to create a rotating Planet for my program ( the rotation itself is fine... but it feels like the image is moving left inside a circle frame ) . I was told I need to add depth, bump so to say. I've tried to add a bit of bumpmap with gimp
But it does not feel round... I'm obviously no expert at Gimp. What should I do with the following image to make it feel more round, the center should feel like it's higher...and the corners should feel like they are going around to the back.
I can create a rotating image with sevaral images in Photoshop? Much like a gif? Would this improve my page load time or would it be the same as loading a slideshow? Here is an example of what we wanna do
On solidworks, There is an option to rotate the profile along the path as it sweeps. I'm curious if there is anything similar to that ability in Inventor? And if not, if there is a way to create a helix along a curved axis.
I have a part that I am inserting into an assembly, the assembly consists of a 2D AutoCAD Architectural background. I want to align the part, with the background itself, so I just need to turn it 90degrees. When I do a rotate, it keeps rotating it on a 3D axis, including when I use my grip edit, and use a line to align for the new rotation.
How do I quickly rotate a part so that it's not rotating on a 3D axis, it just rotates along the x,y axis?
I am right now working on a door with a door handle and a lock.
So far i have gotten the door handle to work more or less.. The only thing that annoys me is that when i rotate the door handle to the limit, it'll reset rather than "lock" and just wont move anymore.. Anyways, that's not my main issue here.
My main issue is that when i mess around with the lock-handle, it will often interfere and pull in the doorhandle, change the location and just act odd..
It is no problem the other way around. I have no problems using the doorhandle without it doing anything to the lock.. I have tried to make more space between the two handles, but it makes no real difference.
I have an assebly where i have imported parts and other assemblies. Unfortunatly during process of assigning them together they have rotated by various angles.Is it possible to somehow "reset" the rotation of part according to global xyz?
I'm using 2010 and maybe this has been addressed in subsequent versions, i don't know.i've designed parametic platform that I would like to insert into an assembly and have it prompt me for elevation and orientation. Short of VBA code, i'm not sure I can do this. I AM trying to make the process as simple as possible for use by people who will not be overly familiar with Inventor. The easier it can be done, the sooner it can be adopted and more people taught how to actually use it.
I know I can bring it in and constrain it different axes and planes.
I also know that I can insert a piece into an assembly and ground it at 0,0,0. Using that I can ground it at 80 feet in the air or whatever elevation I choose using the occurrence tab of iproperties for the part/assembly. That in and of itself goes a long way toward what i'm trying to do. There's also a rotational setting there that would work for setting an orientation, but it's greyed out. In fact, in any example I try and make, it's always greyed out.
I've tried doing it as an iassembly as well, but there doesn't seem to be any provision in iassemblies for making custom values like there is in an ipart.
Either a dialog to prompt for the info or via something like the occurrence tab is fine.each identical assembly/part has to be individually constrained to get the correct orientation?
I am trying to create a simulation in which a shaft rotates and the a spur gear attached to the other end rotates with it. When I apply torque to shaft, the shaft does rotate but the gear does not. I believe I have done something wrong with the constraints.
Motor Model 1:1 is used to turn the wheel holders at various angles. The part named "front gear spring holder" is supposed to revolve and turn the inner part of the "front wheel holder" My problem is that I want to simulate the turning of the front wheel's using contact sets or 3d/2d contact sets in the dynamic simulation environment. I do not know how to do this, but I'm almost certain the program is capable of doing so. Also the spinning of the front wheels must be able to be done along with various angles of the front wheels(while turning, the front wheels must be able to still spin with the front gear spring holder".
I have seen threads and articles that say that making gears with contact sets is not recommended or possible but i have two instances here where they work perfectly fine using the dynamic simulation with 3d /contact sets. Take a look at the simulation I have saved as well.
I will need more on this assembly in the future, including how to create bevel gears that work at 90 degree angles or spur gears with contact sets instead of just simulating their movements .
What would cause my frame generator parts to rotate when I change a completely different part on my frame. they seem to be off by a very small amount. they seem to rotate everytime a change something else in the frame and can change them to be correct.. I believe my main sketch is constrained.

I have been unable to rotate the header text in a parts list. I created a new text style that is rotated 90 deg, a new part list style that specifies to use that text style in the header. Everything else about the text in the header displays correctly (i.e. font, size, colour, etc) but not the rotation when I insert the parts list in a drawing using the correct standard. When I apply this same standard to a regular text line on the drawing it will rotate the 90 degs but not in the part list.
I am working on one frame where I have rebuilt two parts multiple times and they still revert to being rotated slightly after performing a rebuild. I can continually hit the rebuild button and watch them rotate back and forth. Is there a known fix for some of these oddities with FG?
Notice the two tubes in the attached pic. I do not understand why they continue to rotate out of alignment after they are placed correctly. (They even look fine when placed.)
I want to make an assemby consisting of 3 parts. A crank shaft and a crank pin that screw into threaded holes in a crank disk. How can I insert them and prevent them rotating in their holes but still allow the whole assembly to rotate around the axis of the shaft? Also how could I lock a flywheel on to the shaft so that whole assembly can rotate togeather?
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'm trying to figure out how to create an iLogic rule that would create a Custom iProperties and put in what version of Inventor the file was last updated with.
I dont know if its the UCS thats twisting or something else thats happening . If you look at the screen print i attached you can see that the view cube is orthogonal but the cursor is slightly rotated. If i restart my computer this will not be the case.
Then the cursor and the view cube both will be orthogonal. But after a while, for no reason it will rotate again and I have to restart my computer!
I have two questions about UCS creation/rotation and the AutoCAD PLAN command:
Question 1) I am creating a new UCS, rotating it based on user picks and saving it. The problem is that it saves the new UCS origin location, but it will not save the rotation. The code I am using was pieced together from a couple of different sources (.NET developers guide and code from Tony T from an old thread) How can I make the new UCS "save" the rotation as well?
Question 2) Once I have the new UCS created, I want to esentially use the AutoCAD PLAN command and rotate to the name of the new UCS that was just created. I cannot find ANY info anywhere on the internet on how to replicate the PLAN command using .NET. Here is the code I am using to create, rotate and save the UCS:
Dim acDoc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument Dim acCurDb As Database = acDoc.Database Dim acEd As Editor = acDoc.Editor Dim acEnt As Entity = Nothing Dim Zaxis As Vector3d Using acTrans As Transaction = acCurDb.TransactionManager.StartTransaction()Try ' Check for the exisitence of required blocks. [code]....
I am trying to write a tool using the .NET API (C#) that will allow me to select a block that currently exists in the drawing, and then select a line, and the tool would calculate the necessary axis of rotation and the amount of rotation to rotate the block into the same orientation as the line. Both the block and the line might be skewed in 3 dimensions. The use case for a tool like this might be for drawing a tubular space frame. I would first define nodes and center lines for the frame, and then have a block of a standard structural member. I want to insert that member multiple times and "snap" it to a center line. I tried using Alignment Parameters.
However, these don't seem to work in all cases. I need to (or rather, SHOULD be able to) create a tool that allows me to re-align an existing block currently inserted into the drawing into a new orientation in 3D using any arbitrary line as a reference line. Clearly this can be done because it is done all the time in Inventor. A similar feature seems to not exist in Autocad.
In order to do this I believe I need to choose some vector to use as a reference within the block. For example, I might choose the BlockReference.BlockTransform.CoordinateSystem3d.Xaxis, and then rotate this vector so that it is equal to whatever reference line I have chosen. The problem I am encountering (and that I think many have encountered) is in understanding how to use the BlockTransform correctly to arrive at the points I need to do the necessary vector calculations to determine the axis of rotation and the degree of rotation such that I can call the BlockReference.TransformBy() method correctly and reliably.
Many posts say to "Use BlockTransform" but then don't go into any detail. There seem to me many pitfalls around when one can use the BlockTransform matrix, and on which objects, and what the results are likely to be based on one's current UCS etc.
I'll start by saying that I'm using Civil 3D 2012...I've made a custom line type and am having issues with it. Basically, I'm trying to get the text (Green line with 4's) to flip around from it's current orientation, see attachment. I have already tried the REVERSE and MIRROR commands, with no success.
what i have is a section cut that my Mechanical guys use. What i am trying to do is create a dynamic block using the rotate parameter.
Currently i have two rotate parameters. One to rotate the section cut lines around one bit of text. The second parameter is to rotate another bit of text, but this is also selected in the first parameter.
It is almost working... with the exception that when i use the main rotate grip everything rotates around the text i want it to, but the second bit of text rotates 180° the opposite direction.
I frequently rotate my drawings around the Z axis however when trying to do this in 2013 it only appears to let me rotate at 0,0,0 rather than clicking on 2 points in the drawing to reference the angle at which I wish to rotate to........ Im not sure if this function has changed completely or is there something I need to set to still allow me to do this?
