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 :: 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 :: 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??

AutoCAD Inventor :: Changing Sheet Metal Thickness And Bend Radius

Mar 13, 2012

I wrote an app some time ago that swaps out user parameters that drive sheet metal thickness and bend radius.

it appears to work about 60% of the time when it doesn't it does not give any warning but even though the FX table shows the new user parameters driving thickness and bend radius the "sheet metal defaults dialog" thickness input box is grayed out and shows no value what so ever.  Clicking the Edit Sheet metal rule to display the "Style and Standard Edtior" the Thickness and Bendradius still show the Old userparameters.  See attached Pic.

I am setting the parameters as follows.

Replaced "Chan_Th" with "chn_thk"  in FX Userparameters

then...

[Code]

oSheetMetalCompDef.UseSheetMetalStyleMaterial = True       oSheetMetalCompDef.ActiveSheetMetalStyle.Thickness = sThick

[/Code]

As you can see FX reports the change but sheet metal settings does not.

This code appears to work or not at random.

AutoCAD Inventor :: Sheet Metal From Flat Sheet To Rolled Part?

Sep 12, 2013

A collegue asked me about this as he has been given a part to model and the details are for the flat sheet not the finished model. Is this possible in 'sheet metal'? I had a quick play but couldn't work it out. Im used to creating the finished part and 'un-folding' to get the flat pattern.Detail supplied below.

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 :: Sheet Metal Bin - Add Flange

Aug 8, 2013

I am working on a bin type unit, and am having trouble creating a flange, I am creating the bin in the final product stage, then I will separate into manufacturer components. I am having trouble adding this flange around the top 4 edges of the bin. I need the four corners to meet on a miter 45. I will then rip down each seam and have 4 separate panels.

Is this a bad workflow? Is there a better route? I attached the part in Inventor 2013 format,

AutoCAD Inventor :: How To Model ACM Sheet Metal

Oct 20, 2011

Very thin gauge aluminum sheets with a composite sandwiched between them.

The challenge is, the panels are relatively thick, 3mm or 4mm, but a router is used on the fold lines before bending to cut through all but the outer aluminum.  This makes for a very tight bend radius.

So, thick 3 layer material, tight bend with mitered corners.  Can Inventor's sheet metal tools handle this?

AutoCAD Inventor :: Normal Cut In Sheet Metal

Sep 6, 2012

how incredible it is that Inventor still does not have a functional normal cut option for sheet metal like Solidworks and Solidedge have long had and I agree.  I realize that there are the standard workflows like using derive and thicken to get around this problem.  However, for those interested, there is a way to make a normal cut (for laser/cnc) directly in the sheet metal part in many cases.  It involves using a sketch to split a face and then using the resulting profile for a thicker/cut feature.  I'm always interested in any other methods out there for obtaining normal cuts in complex sheet metal (for a clean dxf export).  By the way, Autodesk, do you actually not have any plans of ever adding functionality in this area?

AutoCAD Inventor :: Sheet Metal Extents Add-in?

Jul 3, 2012

I am using IV ultimate 2013

just found about this add-in:[URL]

But its not working for me:

I ran the installer, created a sheet metal part and hit rebuild all, it did not create any proeprties, also tried to manually create the properteis then hit rebuild, no go.

I also did a search on my hardrive for the ApplicationPlugins, and placed the sheet metal folder in all of them(there were 3) tried again noto.

The add-in also does not appear in the add-in manager.

Or is there different what to get the flat pattern dimensions in 2013

AutoCAD Inventor :: Cannot Convert To Sheet Metal

Dec 7, 2012

I have just modelled a part with some faces and tried to convert to sheet metal to have inventor make the bends between the faces. However when trying to convert to sheet metal i get the following error message (Autodesk Inventor Professional Tip) - "This model cannot be converted to Sheet Metal because it contains features that have created multiple bodies. In order to convert to Sheet Metal these features must first be removed."

As the picture show the part only has 1 solid. Even when deleting all features except the "base" face I get the same error message or Tip as Inventor calls it.

AutoCAD Inventor :: Sheet Metal - Cut Across Bend

Dec 20, 2012

I have a sheet metal door with a little bracket that gets welded to the inside lip through a cut-out in the face of the door. (see assembly)

I can't get the cut-out to line up flush with the inside lip of the door, as that is where the brackets gets welded to. the current aseembly is set-up the way I want, but I can't get a flat pattern on the door, becasue of the cut going across the bend.

I have checked off the "cut across bend" in the cut dialogue box, but this leaves a small (~1/32) lip in the cut-out and runs interference in the placement of the bracket.

AutoCAD Inventor :: Slice Sheet Metal

Nov 13, 2011

I was designing a part which consisted in a circular sheet metal part with a hole in the center, and a bent rectangular radii-oriented section. The second feature is the one I want to give focus in this thread.

Take a circular sheet metal with a diameter of 30 mm and a thickness of 1 mm. Now, to achieve the bent section one would perform - in a workshop or any other equivalent - two parallel slices of about 5 mm in length with a distance from each other of 4 mm. The slice would start in the circumference and end somewhere nearer to the center of the disc, but not parallel to a radius (since its parallel to another slice 4 mm apart as said before). After the slicing was done, one would bend the section between the slices 90 degrees to any of the sides.

Now, in Inventor I couldn't find a way to do this. I couldn't just slice a line through the disc. I worked it around by cutting rectangles of 0.2 mm in width and with the length of the desired slices, and then using the folding command to bend it 90 degrees. Is it possible to perform this so called slices?

AutoCAD Inventor :: Interlocking Joints In Sheet Metal

AutoCAD Inventor :: Sheet Metal Rule In Drawing

May 7, 2012

I have setup all our Sheet Metal Rules to be all of our stocked in house sheet metals.  The sheet metal rules are named like:

ALUM 5052 H32 1/2" (Part Number)
ST STEEL T304 3/8" (Part Number)
STEEL 44W 1/8" (Part Number)
etc.

And each rule has the proper thickness, material, and some standardized bend radius's.  I've done this to introduce more uniformity in our designs, and to also allow the designer to put as much information into the model as possible, so that if someone else does the drawings, there is no question as to which material is used.

I now want to bring in the Sheet Metal Rule name into the drawing automatically.  I can't seem to find a way to reference the Sheet Metal Rule directly from the drawing.  What I need to do is pick a standard field in the i Properties (I used Stock Number), and put in =<Sheet Metal Rule> so that now the Stock Number references the Sheet Metal Rule, and then in the drawing I can just reference the Stock Number, and it will come in.

I don't like having to use the Stock Number as a middle man though, as none of our existing models are setup like this.  Is it possible to reference Sheet Metal Rule in the drawing without having to use another field as a placeholder for the information?
