AutoCAD Inventor :: Spline One End Of The Shaft
Nov 18, 2010
I have created a shaft and splined one end of it successfully. The shaft is the same diameter at both ends and I need to spline the other end as well but when I try, I get the following error messages, Cannot create iFeature. Not possible to create shaft groove. Splining the first end went without a hitch but Inventor absolutely refuses to spline the opposite end of the shaft. The shaft diameter is correct for the spline I have chosen (same as the major diameter)

I'm trying to create an external involute spline (ANSI B92.2M) Fillet Root Side Fit 26.9mm x 1 mm x 26 teeth x 38 mm long using the spline generator with Inventor 2012. I created a test shaft"M-182-AMA.ipt" that is Ø26.9 mm x 38 mm long with 1 mm radius on each end of shaft.
I use the following steps:
1. After creating component "M-182-AMA.ipt" I select Design tab>>Power Transmission>>Involute Spline.
2. A window appears that has the caption "Involute Splines Connection Generator".In the Dimensions section I choose "Splines Type: ANSI B92.2M - 37.5 deg, Fillet Root, Side Fit, 26 x 1.00 x 38 x 5H/5h" and change the Length to 38 mm.
3. In the Shaft Groove section I use Create new, and I push the Reference 1 button that turns blue, I then select the od feature from the model and I get an error(see attached pic "error1.jpg).
I changed the 26.9mm od to be 27mm and it still gave me the error.

How can I put a 'center' into a shaft end in inventor? I have been doing this using the point/hole command and altering the csink details until I get something close to what I want but obviously not ideal.

I am using the design accelerator to create a shaft with multiple features. Works well. This shaft is 90"+ in length and although I realize we create in full scale, having it display into my drawing in full scale is unnecessary because one diameter is nearly 60" long. As such I would like to shorten it by using a shaft end, but cannot figure how to do it.
Just to be clear, by shaft end (term used in Mechanical) I refer to the squiggly lines that basically fudge the OAL of a component.

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.

I have written some VB code which updates parameters in a model. I would like the code to update the shaft parameters. The shaft is created using the shaft generator. I can use a parameters to set the lengths, diameters and fillets. But when the parameter updates the length stays the same. If I open the shaft assembly, click 'edit using design accelerator' and then click 'ok' in the window the shaft updates. Is there anyway to do this automatically?, maybe through iLogic or API?

Questions below pertain to using Autodesk Inventor 2013:
What factor of safety value the Shaft Generator program uses when you run the calculations?
Does the factor of safety value change when you are not using the inventor user material option?
Lastly, when exactly do you know when to use the density option in the calculation properties or not?

i am trying to design a shaft with a cut out that would cut along the shaft a a set angle and wrap around the shaft.
I am going to have a bearing ride along the cut out and cover this to a linear motion but can't seem to grasp how you do this in inventor 2013.

what I would like to know is the 'simple' way to create a keyway on a shaft in the middle that does not connect to the ends. End connecting keys are pretty basic to draw and extrude thru (maybe still a better way?)

Trying to dimension a shaft in isometric view with various diameters. I am unable to find or select the centerpoints at the ends of the shaft. This causes dimensions to be crooked. How can i get the centerpoints to display so that they may be selected?

I'm using Inventor Professional 2014
I created several Parts with the Shaft Generator, and from one moment to another it always says that it can't update the part file with the new shaft when I press Ok.
Here is the original error, I'm german, so of cause its in german, but i discribed above what it says:

How I could go about creating a standard locknut thread, with the shaft generator (easy so far) BUT create a proper single rounded end key way? It does the end of the locknut groove with the rad that exits the shaft, but in complete truth (and 15+ years of experience.) I have never seen this done in the real world.

is it possible to produce something like in the attached image using the design accelerator? Instead of making a cylinder and sketching the spline patterns and extruding? To me there must be a way besides sketching and use the library's of standard splines patterns and sizes.

I create a engine assembly and used "Drive Constrain" to rotate the crank shaft. The animation shows the crank shaft turns continuously in one direction. However, when I animate the constrain in Inventor Studio, the crank shaft turned in two different directions (see the vide file attached).
May I know why the crank shaft turns different direction?

Here I enclose file Cam_Profile.ipt, this is a spline curve made from an Excel matrix with 670 points in 3 decimals accuracy (VBA editor)
Extruding is not possible because of self intersecting path.
I want to trim both two free ends from the intersection and also close the intersection for extruding this profile. However ....., without displacement of any current point in the perimeter of the closed spline!

I have a group of Points coming from a step.file. So I don't have their coordinates, excel list or anything else. Just the step file. Around 100 points. There is a line between each 2 consecutive points.
Is there any way to select all the points and create a complete spline? Or even to select all the points and create tangent arcs between all of them?

In Vers 2013, IV finally added the ability to manipulate a [3D] spline by dragging the control handles (way behind the curve on this one).
However, dragging "a" control handle causes several of the other control handles to shift as well. Puts a big limit on the ability to customize yout path. Splines are supposed to be one of the unrestricted free form tools for modeling.
Is there any way to turn this "feature" off ? I need and should be able to have discrete control on each control handle. (I had this way back in SW)
Also, there is no 'axis' for the control points unless you count the const lines that connect the control points and I don't. I should be able to select an axis and be able to shift the direction and level of influence of each side of the control point axis.

I have a spline that runs through about 70 points to make the perfect line. But when I rotate the sketch the spline turned from green to black and is no longer recognised as a boundary. I then have to delete the black line and re-draw. How do I keep the spline green and usable?

When attempting to break the link on a projected spline, the spline type reverts to what appears to be the legacy AutoCAD type of spline (see image).
Is there a way around this other than drawing a new spline on top of the projected geometry and working with the new spline?
The idea was to project the shape, break the link, then ,ove the shape to a new location in preparation for a lofting procedure.

I am currently attempting to dimension to a spline in an orthographic drawing and running into some issues. I can't seem to find a way to properly dimension rather than making microscopic holes in the piece and that way giving the .idw something to grab on to for dimensioning.

I am totally new to Inventor. I have a lot of experience in Illustrator and Photoshop; what I want to do is possible in those programs, but I have not figured out how to do it in Inventor.
Essentialy, I want to make a closed path from a spline and a straight line— this will become a custom shape that I want to turn into a solid. Is it possible or should I just use the split feature?
In the end, I am trying to make a solid that is similar to a section of this necklace, minus the curved portion that connected them to the necklace, itself.

I am drawing an airfoil profile in Inventor for use in a CFD package. I have a system of points which I am plotting and connecting via the spline function and extruding them to form my blade profile. However, when I open the drawing in the CFD programme, it is recognising the spline as a series of straight lines instead of one continuous enclosed shape. The CFD programme I am using require a negative (i.e a solid drawing of where fluid is flowing). I have attached the inventor file I have created.
