AutoCAD Inventor :: Sheet Metal - Fold (bend And Twist)
Apr 23, 2012
I have the following sheet metal application: A flat bar steel (strip) 40x1mm is bent and twisted around three cylinders. In our process, the strip is running in loop around these cylinders, like a conveyor-belt. At first, it is bent around the first cylinder (blue). Then, it is bent and twisted around the second cylinder (green). Between these cylinders, a flat part is modelled so that the strip will be bent upwards (twisted) around the next cylinder. The same is done between cylinder two and three. In praxis, when I bend the strip, no flat part will be present, because the strip is quite stiff, as it is spring steel. In my Inventor model, no stiffness of the strip is taken into consideration.
I am looking for a better way to model this strip, where stiffness of the material is taken into consideration.

The left-hand part was created by someone else, using the bend part command in the "modify" tab.The right-hand part was created by me using fold in the sheet metal environment, using the same sketch.Why, is my part shorter?

Does a low cost or free software program that could simulate folding of sheet metal patterns so I can work out the best fold sequence eliminating collisions etc.. Based on my stock tooling shapes and sizes and machine limitations?

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.

Ive imported a CATIA part and I'm trying to redraw it in Inventor. I have the main panels and bend rads in but I cannot for the life of me work out how to model the bend reliefs so they are similar to the ones on CATIA. The purpose of all of this is too reduce the bend reliefs that CATIA has produced even further.
Ive added both the original dumb solid from catia and the new inventor model to an assembly and contrained them in line so hopefully you see what I mean.

I have a large number of parts that are set with a "2mm" Bend Radius.
1. I wish to change it to "1.5mm" but manually takes time . Ways to automatize this?
2. What Bend Radius is recommended to be used for steel sheets (1.5 ; 2; 4; 5 mm).

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.

I want to connect two sheet metal faces with a bend. Bend works if two parallel edges are selected. Is there a way to connect two faces with a bend if the two edges are not parallel?

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.

I just what to cut a sheet metal,
and I don't know how (see in Capture.JPG where i what to cut, and test.iam what I what to cut).

Working with sheet metal and laying out a pattern for the cnc and was wondering if there is a way to imprint an extrusion onto the surface instead of cutting it. Mainly this will be used for a marking tool so the line type or layer would need to be different.

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,

Attached are two sheet metal parts that we need to unfold and make them flat for a drawing. We cannot seem to capture the reference A or reference B planes asked for by the unfold command.

Is there a way to get the appearance of perforation on a sheet metal tube without having to create each and every hole? Looking for an appearance to drag onto the surface. Kind of like when you make a part look like it is made of brick. It being just an image on the model surface.

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?

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?

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

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.

How can I create a sheet metal jog? Like the attached. I used a contor flange to creat this one, but I have to add a jog to an existing part and don't want to have to totally redraw it just to get the jog. I'm hoping you can add it like you can a flange.

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?
