AutoCAD Inventor :: Variable Spiral Thickness

Oct 20, 2011

Is there a way to use the coil command to make a spiral out of a rectangle where the thickness of the rectangle starts at one value and ends at another? This would be a spiral torsion spring with decreasing thickness approaching the center.

AutoCAD Inventor :: Set Sheet Metal Rules Thickness To A UserParameter Variable

Sep 16, 2011

We are using 2011.I created a VBA tool that populates the FX Userparameters with a Thickness Variable..How do I set the Sheet Metal Rules Thickness to the new new FX UserParameter Thickness Variable?

for example:

The Userparamter variable name is "cab_thk"

Under Sheet Metal Defaults | Sheet Metal Rules | Sheet (Tab)

The Thickness entry should read "cab_thk"

AutoCAD Inventor :: How To Flatten A Spiral

Jul 18, 2013

I'm trying to flatten a section of sheet metal so i can get a cut lenth for my fab shop. Please see attached drawing. I want to use these dimensions, and then flatten the part so my fab shop can trace it and cut the sections, bend them and weld together, but when i use the flatten command, nothing happens..

AutoCAD Inventor :: Spiral Pattern For A Feature?

Nov 21, 2012

I have a tube which I'm adding a pocket to the outside by removing some material. I then need to array that around the tube. However I need to offset each pocket along the length of the tube. I've attached the tube with one pocket (v2013) and a picture showing the pattern if the surface of the tube was unwraped.

AutoCAD Inventor :: 2D Equation Curve For A Parabolic Spiral

Jun 22, 2013

what the 2D or 3D equation curve for a parabolic spiral, otherwise known as a Fermat's spiral would be? I have found this info but do not know how to apply it:

Fermat equation

Therefore in terms of the affine plane its equation is
The Fermat curve is non-singular and has genus

I have also found this: $r^{2}=a^{2} heta $ 

Please see image attached.

AutoCAD Inventor :: Drawing Logarithmic Spiral / Projecting On A Sphere

Sep 19, 2011

I need a path on a sphere like on the image I attached (sphere_spiral) for the result similar to image called "gomb". The only problem, metric spiral or coil  / 3d helical curve path won't work because it doesn't end the result I need, because the lines are converging each other. So, I figured out I need a logarithmic spiral 2D sketch or maybe a sinusoidal path.

I need a path from the sphere's top center point to the bottom center point, projected to its surface with equal distance of lines.

AutoCAD Inventor :: Creating Flat Pattern Of A Coil / Spiral Shape?

Sep 25, 2012

Is there a way to unfold a coil shape to get the flat pattern? When I try to unfold the attached part I get an error message (see attached error_msg.jpg). We have been using AutoPOL to unfold these kind of shapes (which works fine). But since we have a very old version which we really need to upgrade, I was wondering if nowadays Inventor could handle coil unfolds.

If this will not work with the current IV2013 release, will this then be implemented in a future release? Are there any alternatives or should I just go for the AutoPOL upgrade?

AutoCAD Inventor :: Making Spiral Shaped Pattern Of Parts Around Axle

Feb 28, 2013

It is all about making a spiral shaped pattern of parts around an axle.

what I found in a topic is:

1.Make pattern of workpoints in part file.
2.Make pattern of components in assembly file to follow part pattern.

1st part is easy and done with coil and pattern within the ipt
2nd part does not let me select the workpoints as feature pattern.

AutoCAD Inventor :: How To Add Material Thickness To A Face

Feb 13, 2013

How can I add a material thickness to a face trimmed from IGES file?

I have a surface imported from IGES file, then trimmed to a single face in IV that I would like to materialize.

I tried times for thickness, but IV doesn't like it.

Neither can I apply Shell for part, nor thickness adding from Sheet metal.

It is a 3D Lofted surface, very simple single one.

AutoCAD Inventor :: Find Sheet Metal Thickness?

Oct 24, 2012

I am looking for a solid way of finding the Thickness parameter of a sheet metal part. I have tried two ways so far:

1. oCompDef.Parameters.Item(Thickness)

This works but if Inventor is installed with a different language pack like German for instance then it fails

2. oCompDef.Parameters.Item(1).Value

This also works but if the user started the part with a normal part template and then converts the part to a sheet metal part down the line, then this method fails.

AutoCAD Inventor :: Finding Minimum Wall Thickness In A Part

Jul 10, 2013

are there any other analysis tools available to find the minimum internal wall thickness in a part?  I'm aware of the cross-section tool, but that only analyzes an area the user has already noticed.  In a prismatic part with several cross-holes and features (cavities), it could be easy to miss a thin spot that could give up under internal pressure just by 'eyeballing' the part with Hidden Edges turned on.

I guess I could try the 'unground and move the part thru a sectional plane' trick, but I think it would be too haphazard, especially if the weak point is not thru a principal plane.

Is there a tool I'm missing or maybe something that has been added in newer releases?  Maybe this is too much analysis to ask of a modeling package.

AutoCAD Inventor :: Stress Analysis Thin Sheet Multiple Thickness

Jul 3, 2013

I have an assembly of multi-thickness, thin sheets, essentially welded together. (see image attachment)

One component is composed of land and bay areas, a single planar sheet where the edges are thin, and the central body is thickened.

I can get Inventor to treat the remaining multi-thickness, right angle components as midplane by going with separate bodies.

The top plate is a single planar sheet, and Inventor will not treat it properly as a mid-planed plate.

Will Inventor translate the constraints properly if I build the thin region separate from the central thicker region in order to produce feasible mid-planed mesh?

Question already posted by other in forum - using local control to develop multiple element thicknesses through cross section of plate (by thin face selection), one cannot verify that the smaller elements along the cross section are built properly through the entire component.

AutoCAD Inventor :: Thickness Of Each Of Layers In Assembly Are Generated From Part File

Dec 13, 2013

I have an assembly in which the thickness of each of the layers in an assembly are generated from a part file that is split via a sketch. I use the Make Components tool to break the part into the individual layers, which also spits out an assembly. 

Is there a way to push the thickness value of these parts that will update automatically if the thickness is changed in the parent part, in order to reference this property on the drawing?

AutoCAD Inventor :: ILogic Rule To Insert Sheet Metal Thickness

May 1, 2013

In my title block I have a material section that pulls to iProperties from the model

One is material, which displays the material used in the model

and the other is manually input by me in the comments section of the model, I typically only use this field for sheet metal description, example, .125 Sheet Metal,  this saves me from a drawing view to show thickness only.

In my sheet metal template I have checked the little box for the thickness model parameter so it will show up as a custom property - model.

So i can display the thickness parameter anytime the sheet metal base view is placed.

My issue is I want the thickness property to have the following with it "Sheet Metal"

But I only want this to appear if the base view is in fact sheet metal, all other parts and assemblies, this field would be blank,

So this is what I want when a sheet metal part is placed:

This is what I want to display when a part is placed:

This is what I get when anything is placed:

Sheet Metal shows up because:

I am looking for a Rule that will only apply <Thickness> Sheet Metal to my title block only if the base view is in fact a sheet metal part. Is this possible??
