AutoCAD Inventor :: Dimensioning To Spline In An Orthographic Drawing?

Mar 21, 2013

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.

AutoCAD Inventor :: Dimensioning Holes In Drawing

Jan 25, 2012

I have a couple of quick questions about dimensioning holes in drawings .

First, if I have a hole in a rod or shaft so the surface isn't a full circle I get the dimension as a radius. Can I change it to a diameter?

Second, in a model, how do I dimension or measure to the edge of a round rather than to it's center? In SW I could hold the shift key while selecting, is there a similar method here?

AutoCAD Inventor :: Automate Dimensioning Of Drawing Views

Feb 10, 2012

Is it possible to automate dimensioning of drawing views?

Here's the situation: I have an Inventor assembly that's controlled entirely by iLogic. My users, who have zero Inventor training/experience (or with any 3D CAD software for that matter), pull up the assembly. They enter product related parameters from paper work orders into an iLogic form and hit a "Go Button". The assembly updates based on the parameters, suppressing and unsuppressing parts, features, patterns, and mates.  This works great.  They then hit a "Run Job" button. This takes them to an .idw where they fill out another form with order specific information and hit another "Go Button". This then cycles through every detail sheet and the parts list, deleting sheets deeemed unneccessary for the product, generating part numbers, exporting dxf's, generating an excel BOM, etc.

This works great as well. The problem is with the dimensions.  They blow all apart when the model changes.  I know I can run some API code to delete dangling dimensions, but is there away to programmatically create dimensions so I don't have to rely on my users remembering what needs them?  I've played around with using model dimensions, but I find that they stay and remain attached even when their corresponding feature gets suppressed.

AutoCAD Inventor :: Spline Design Generator - External Involute Spline Error

Sep 28, 2011

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.

AutoCAD Inventor :: Using Created Dimensioning Styles

Feb 27, 2012

I needed to create new dimensioning styles - that I can do.  However, there doesn't seem to be a way to apply them to a current drawing.  In the Annotation section under Format there are no "styles" listed  - not even the default.

So, how is one able to populate the list so one may choose a specific style or another?  Or, is there somewhere else I should be looking?

AutoCAD Inventor :: Ordinate Diameter Dimensioning?

Aug 10, 2009

I design molds for the rubber industry and I was using Acad 2000; I am just now starting to use inventor. I need to used the ordinate dimensioning although I need the dimension to be given as a diameter and not as a radius. Is there anyway to scale the ordinate dimension automatically as 2:1? This way when I give the prints to the tool room they don't have to manually double every diametrical dimension. The prints that I draw only show half of the mold, there for needing a 2:1 dimension scale.

AutoCAD Inventor :: Dimensioning Angles In 3D Sketches

Oct 4, 2013

In the course of working up a tooling proposal, I attempted to replicate a 3D part from a customer print. While doing so, I noticed that 3D Sketch will not, under any circumstances that I can find, allow an angular dimension between a line and a plane. The customer print has two pipes projecting at odd angles from a base flange, one of which has an elbow. The print lists datum dimensions for the open pipe ends and the elbow, and gives vertical and horizontal angular dimensions to define the directions in which the pipes emerge from the flange. I have defined these three datum points in 3D space without any trouble, but Inventor 2013 will not allow me to define an angle between these sketchlines and the XZ and YZ origin planes, or between these sketchlines and the faces of the flange base I've constructed.

I am currently waiting on a proper 3D CAD model from the customer, and I'm considering longhand trigonometric calculations to place these lines properly, but I find it very hard to believe that Inventor is incapable of constraining a line to lie along what is effectively the surface of a cone.

Inventor 2013
AutoCAD 2013

AutoCAD Inventor :: Dimensioning Suppressed Parts

Feb 28, 2012

I have created some "programs" to automate drawing creation of some of our most common products. The problem I hav eis with my assembly drawing. When parts are suppressed and unsuppressed, they don't seem to behave the same way that features do. When you dimension a part feature in an idw and suppress that feature, if a week later you unsuppress that feature the dimenensions come back.  Parts don't seem to follow this behaviour. If you dimension a part, suppress it, open and save the drawing, then later unsuppress it and open the drawing back up the dimesnions do not come back. Is there anyway for me to get these dimensions to "stick"?

AutoCAD Inventor :: 2D Dimensioning Quality - Adding Text Label

Feb 6, 2013

I find the 3D side of the software is great for modeling. But when it comes to the 2D drawing side of it, especially dimensioning and the adding of text label is very poor, when compared again other CAD packages including AutoCad Mechanical and LT.

Why is it not on par with AutoDesk other 2D packages!

AutoCAD Inventor :: Create New Dimensioning Styles For Company To Use As Standards

Jan 25, 2012

I'm using Inventor 2010.

I've been told to create new dimensioning styles for the company to use as standards when making a drawing. One thing mentioned in particular was the inclusion of 0 inches in architectural drawings.

For example: say a part is 14 feet, 1/2 inches long. Inventor shows this: 14' - 1/2" , but they want this: 14' - 0 1/2" . They've had a problem before with the 1/2 being printed strangely, and the machinist thought it said 1 1/2.

They say that including the 0 is standard, and I need to make it happen.?

AutoCAD Inventor :: Dimensioning To Central Axis Through Multiple Sketch Planes

Dec 3, 2011

I am creating a part that consists of a series of intermediate Lofts.  The various Loft termination profiles are sketched on a series of stacked planes, most of which are parallel to one another.  I have a Work Axis (oriented at an angle off of true vertical) that penetrates all of these sketch planes, essentially forming a "central axis" for my part.  Most, but not all, of my sketch planes are normal (perpendicular) to that axis.

I want to use my "central axis" as a reference point in each of my sketches, i.e., the point where the axis intersects the sketch plane.  I am having a minor difficulty.

When I project my central axis into a sketch whose plane is normal (perpendicular) to the axis,  Inventor displays a reference point where the axis penetrates the plane and I can dimension my sketch geometry relative to that point.  Conversely, no such point is displayed when I project the axis into a sketch plane that is NOT normal to the axis.

Is this correct behavior?   To have a dimension able point on my "non-normal" sketch planes, must I create explicit Work Points to mark the intersection between my Axis and such planes, and then project those points into the related sketches?

AutoCAD Inventor :: Spline One End Of The Shaft

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)
