AutoCAD Inventor :: How To Find Length Of A Bend
Oct 6, 2011
I have some code that find the length of a bend and it works great until there is a cut operation that passes through the edge of the part and through the bend. When this cut exists the systems recognizes the single bend 2 times which is fineand it should, just that it should also then be able to determine the length of each segment. It appears to be providing the length of the first segment twice. Any way to get either the segmented lengths or the length of the bend without the cut? I need a total length and the code below gives wrong data for the one edge length. the attached file shows what I mean.
Sub Bends()
Dim oDoc As PartDocument
Set oDoc = ThisApplication.ActiveDocument
[Code]....

I am try to create a function that compute the length of a line such as the picture shows on top. The code I have now only getting the straight line distance. It's there a way to compute the curve distance?

Is there a way to find the "arc length" of one of my arcs? or can I construct an arc of a certain arc length?

I'm trying to use the cut across bend feature on a sheet metal part. However, when I check cut across bend, it grays out all of the other cutout options, and only has thickness as the only option. This is perplexing to me, because I can't think of too many times I'd need this option other than when there is more than one thickness of material I need to manipulate the profile onto.
I was to understand that this "cut across bend" is for use similar to the "normal cutout" command in solid edge? Keeps the cut perpendicular to the sheet face in a sheet metal part.

I attached an IPT file that a customer sent us to manufacture for them.It's a rectangular aluminum tube with two bends.In the IDW when I try to place center points and dimension the radius it is not recognized.The original file was a STEP.

Under the modify tab in a part file, I can drop down and click "bend part." We have a bunch of frames made out of stock tubing that are welded together, then bent as a whole. Is there a way to bend at the assembly? I want the model to represent the production process. I don't want to have to bend each tube alone, then reassemble. That would double my parts/part numbers.

I have been trying to bend a larger radius on a corner bend but i can not seem to be able to . I start out with a face of 46" x 82" i want to put a 1/2" bend up then a 1/2" bend out to make a z shape i'm using as a material .109 stainless steel and i want to end up with a 1/2" on the inside corners so that when i'm done i can flatten it out to get the proper sheer size for the piece the metal brake i'm using has a 1/2" die in thats why i trying to figure this out is their any way to put this kind of radius on the sheet metal bends.

I'm trying to do a usable and real flat pattern for a laser cut on this type of part and I'm not able to do a cut across bend or other wrap around face feature.
Any method to do such a feature ?

I want to do a simple bend of a cylinder. That is, I have made a 40inch length and want to bend it at several places.
I keep finding a reference to bend part but the tool does not exist in Inventor.

If i have even used the correct technique but how do i perform the bends in the flat bar so as the bottom and top section are vertical and the small mid section is on the angle. At the moment the mid section is displayed vertical when using the cub please see attached files.

I have unfolded a 3D model into a flat plate, however the bend lines/extents do not appear in ISO.dwg
I doubled clicked into the view to access 'Display Options'. However, I cannot tick the box to display bend extents as this option is shaded out (refer to attached screen dump).

I cannot figure out how to dual dimension a bend like so:
DIRECTION DEGREES RIMPERIAL [RMETRIC]
e.g. DOWN 90 R1/2"[13] preferred
or DOWN 90 R1/2"[R13] okay
There should be a degree symbol after the 90 in my examples but I can't figure out how to type it here. I can get DOWN 90 R1/2"[DOWN 90 R13] but it's too long.

Is there a way to make Inventor automatically add a note, along the bend line, indicating bend direction, number of degrees and bend radius?
Also, in 2013, where are the bend tables located? I've checked the help file, and it's telling me cprogram filesautodeskinventor 2013design data
I followed that path, but I do not have the "design data" folder it's calling for.

Inventor 2014 LT / have run into a problem in a throw-away project I"m working on.
A simple example is to create a piece of 3x5x.125 flat bar, add a sketch giving you a bend line and bend the end of it. Now try to mirror the whole thing giving you a 3x10x.125 flat bar bent on both ends.
FWIW: My project isn't this simple - I know I can just make the FB and bend both ends ... this is an example of mirroring a bend not working.

I am trying to save copy as dxf without bendlines so I can directly import the file into my waterject CAM software. There has to be a way to tell it not to add the benline layer.

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.

I am not sure what I am doing wrong but when I use the bend tool I am getting weird results. Does the surface to be bent have to be planar? See photo attachment.

Create a new sheet metal part make it a box of any size add four flanges then create a flat pattern. Save the file then create a drawing view of the flat pattern. All well and good so far... Now create a Table using the flat pattern view as the source, which creates a Bend table just fine.
Place the table on the sheet and Tags are added to the bend lines which is wonderful and great. Now try to move a tag.... BZZZZZZ your time is up you can't.
Yet in your Sheet Metal Annotations in Drawing - Wiki Help page in the Procedures - Create or edit a bend table - Create bend tags section it states:
Tip Drag the bend tag text away from the original position to add a leader to the bend tag. Is this a bug or something not set right on my system?

I want to make this part that bend 15 degree at 800 mm from bottom. In my attempt.
First, I bend it 15 degree.
And, make flange from Face and upper flange then I stuck with error.

Is there a way to preload information into Inventor in regards to the break press such as the dies being used or the ones available so the when the computer is deciding a bending radius,it know what tool we have?
Currently the bend radius is set to "radius", which i am assuming is default, but I can't figure out how to change that either, and depending on the thickness it will change, but like today it said I would need a 1/16th inch radius, but we don't have a 1/16th inch die,it is an 85 degree air bending setup,and has a 4 way die with smaller and bigger openings.

Any way of drawing an edge bend on a flat bit of copper so I can flat pattern it for the guys on the shop floor to make.
The problem comes with the edge bend, I have provided a picture of a simple bit of copper with various flat bends and a single edge bend. As the flat pattern shows to the right the edge bend is not flattered, This was drawn using a sketch the profile then using "face" . This is why I assume it does not work in flat pattern.
Is it possible to draw an edge bend with a command to allow it to flat pattern? if so which command and how?

I dont know why, because I never had this problem before, but I am bending an object and the bend command is distorting the circle I made as a pivot point.

I have tried to do a lofted flange. It works, but there is an extra bend that I don't understand why it is there. The bends, I would assume, should be symmetrical but they are not. I have attached the part.

Just by selecting a bend line on the flat pattern, I'd like to draw only 2 lines on a sketch (without any border projection, only points) at both ends of the bend line.
I'm sure it can be done via VBA, but don't know how to start for it.

I generate 3 points, two lines between point 1,2 and 2,3 and make a bend between the two lines. Cannot do it correctly.
On one side the fillet is not trimmed correctly. I think it is a bug in Inventor. Also when I have the sketch I manually cannot make a decent bend/fillet in the 3D sketch I created.
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 'add 3d sketchpoints in open partdoc Dim oPartDoc As PartDocument Dim oPartDef As PartComponentDefinition Dim oTG As TransientGeometry oTG = _invApp.TransientGeometry oPartDoc = _invApp.ActiveDocument oPartDef = oPartDoc.ComponentDefinition Dim oSketch As Sketch3D oSketch = oPartDef.Sketches3D.Add() Dim sp1(2) As SketchPoint3D Dim rod(1) As SketchLine3D sp1(0) = oSketch.SketchPoints3D.Add(oTG.CreatePoint(0, 0, 10)) sp1(1) = oSketch.SketchPoints3D.Add(oTG.CreatePoint(0, 0, 0)) sp1(2) = oSketch.SketchPoints3D.Add(oTG.CreatePoint(10, 0, 0)) rod(0) = oSketch.SketchLines3D().AddByTwoPoints(sp1(0).Geometry, sp1(1).Geometry) rod(1) = oSketch.SketchLines3D().AddByTwoPoints(sp1(1).Geometry, sp1(2).Geometry) 'bending it oSketch.SketchArcs3D.AddAsBend(rod(0), rod(1), 2.5) End Sub
The resulting part-file is added, for who wants to try to get a bend with both sides trimmed correctly.

When I use "export face as" to create a DXF file for our lazer table I loose the bend lines in the DXF. Is there a way to retain the lines in order to have the lazer scribe the bend lines for us?
