AutoCAD Inventor :: Adding Flanges To Contour Roll
Jul 25, 2012
I've been having some issues recently with Sheet Metal parts. I am attempting to make a part that looks like this:
The only way I have been able to do this so far is by doing a contour roll to get the rounded part and then add the flanges on as part of an assembly.
I have attempted to do it as one Sheet Metal piece but I continually run into the problem where I cannot refold the part once I have the flanges.
Here are the steps I have gone through:
1. Created a contour roll to the necessary angle to get my desired dimensions
2. Unfolded the roll
3. Created my hole pattern
4. Folded back the flanges
This is where I got stuck. I attempted to refold the part between the bends but it will not let me do this. If I have one flange, I am able to refold but not when I have 2.
Another problem I have encountered is when I get one flange done, the thickness of it is larger than the rest of the part.

I'm having no problems creating the contour roll, but it won't let me add flanges to the outside edges. I have attached a file that shows the measurements that I want. I need to be able to create a flat pattern. The material thickness is .1046" and 3" deep.
Inventor is awesome, quick to learn but sometime i get really blocked..Makes 2 hours i am trying everything to recreate a sheet of paper (a4) bended like a cone that isn t perfectly round but with the bottom flat.
I have attached a photo of what i am trying to create.I have tried to make it with using a triangle isosceles as the bottom and curve a sheet of metal using the "contour roll" between the 2 isocele sides.
I am getting an error message (see attached) when trying to create a contour roll using sheet metal, I have tried editing the sketch to open loop however I cannot get the contour roll to preview on the part.
The part is a short length of square hollow section from which I am trying to apply the roll to, there seems to be a problem in projecting the geometry on the end of the part

Inventor 2013-I'm working on a sheet metal cover using contour roll and I find when I dimension the flat pattern that radii that should be the same are not. Can my approach is fundamentally flawed? I tried making this part out of one 220 degree contour roll and I found when dimensioning that the center points of the arcs are not symmetric as expected. I then used two contour rolls to create the part basing the second contour roll on the first contour roll sketches and I still have the same issues.
I am trying to design a welded Iron tank whose caps are made of sections, then welded together. I made one section using Contour Roll on Sheet Metal, and worked fine, but when I made the Flat Pattern it mades a square.
I want to make a contour roll and use the developed length option. How do I accomplish this.
The only way I can get this option to be available (not greyed out) is to have a closed loop sketch, if I have only a single line line sketch this option is not available.
easier way to program 45 degree corners on the top flange of two mating parts. We can't bend the ends on so they have to be welded. I am using inventor 2014 professional. Almost all my programming is done in sheet metal.
I was just wondering if there is an easier method of getting a 45 degree corner on flanges of 2 different sizes. 1 flange is 1" and the other is .75". I have been cutting the .75" flange down and adding to the face of the 1" flange.
The corner I'm talking about is on the far right of the part.
I'm using Inventor 2010 and I have a problem with connecting the sheet metal corners to each other when making round radius flanges. How to connect the corners to each other (even though this is probably not possible in reality). Even better would be if the flat pattern of the sheet metal part would also look proper.
Note that the short edges are 90 deg bent and longer edges are 75 and 105 deg bent. This also makes creating "corner fill" parts a bit tricky.
I am messing around with a part at the moment so if I was to put it up as an .ipt file it would be crucified for not being constrained, dimensioned etc etc.
I am trying to get a 25 and 20mm return fold on the back of a curved panel. No matter what I have tried I cannot figure out how to do this, I manged to get the model bend on it however this will not flatten out in Sheet metal correctly and I will need to send a drawing out in a flattened state.
The folds needed are shown in picture as well as the curved part
They need to go on the outer bend of the plate. If I tell the mmanufacturers to weld it in points along the flange that's ok, I just can't seem to model it to get a final drawing out!
The question is if I have designed a part in sheet metal with multiple flanges and one of my edges follow a specific radius. Is is possible to use contour roll or any other means to create a flange on that edge that will allow me to flatten that out. I cant see it being physically possible putting a bend in there as the material would need to stretch and the bend tool would need to follow that radius.
I am trying to create flanges on the inside of a cut angle from a contour flange based drawing see attached file. I am not able to get the flanges to attach since the material thickness varies due to the cut.
how I would go about adding contour lines to a map? I entered roughly 200 points (x, y, and z values) into an x-y plane on AutoCAD and figured that if I were to add contour lines (1' elevation difference), it would rely on the z axis. In short: how do I add contour lines if the points are all plotted?

The last feature of this L-Bracket is a fold. When I create the flat pattern it is only unfolded, not completely flattened. Prior to INV 2009, I could get a wireframe flat pattern with the part still folded. Since then, I have to unfold to get a flat pattern. The only way to show the formed part and flat pattern in IN2012 is to use a derived part with the base component supressed and the base component with the fold supressed.
How to be able to simply flatten this part so I don't have to do extra work with two parts
I was wondering if it is possible to create a flange on a rib of the wing section using sheet metal features. The point is that the flange is bent along the curve in most of the cases.
I am trying to add contour lines to a surface at very specific elevations (rain event elevations). I can add all the intervals I want but can't seem to figure out how to add a contour at a certain elevation.
I have to make a roll of tape in Inventor, but I'm not too familiar with/used to the program. It's the small invisible adhesive tape, like the kind you'd find in office. So far, I sketched and extruded the plastic part the tape gets wrapped around, which is basically just a small tube. I also have a rectangle that's really long for the actual tape part, and that's extruded but very thin. they're both made as standard.ipt files. I opened a standard.iam file to put them together using constraints, but I'm not exactly sure how. I have the edge of the rectangle on the outside of the circle, so I just have to wrap it around. I'm assuming I just bend the rectangle (tape) around the circle (plastic part), but I don't know how to do that.
I have two cooling rools( just two cylindrical drums) a sheet is been passed on this. Wonder how do i draw the flexible sheet, actually i have many cylindrical rolls placed at different locations - all i want is a thin sheet to be passed onto each of those drums. Just like belt and pulley, but here sheet and a drum. Its very difficult to calculate dimensions and constrain, instead am wondering how do i create a flexible sheet of fixed length and constrain it so that they rest on top of the drums.
I'm still new using autodesk inventor and still learning. I have trouble to cut the plate (Penahan Depan.ipt) follow the radius of the roll (Roll.ipt).
The wheels on the side need to roll inside the guide rail. I can let them roll in each part separately but not in the entire rail.
I already tried with transitional constrains but then inventor says that there are some problems.My project needs to become a sectional gate so there's going te be lots more than just 2 wheels in it..
I made a sketch for a bracket and used sheetmetal/contour flanges tool to make solid.I had to use 2 contour flanges to get the shape as i could not get it to work with 1 contour flange.Is this not possible due to something wrong with my sketch?
Other question is have i used the Cut tool correctly for the cut out of the brackets?
I have sketched a fan casing which consists of a series of tangential arcs. The sketch is fully defined but when I try to use "Contour Flange" I get the following error:
Sheet Metal: Contour Flange Creation failed. 19-3-101-26-2.ipt: Errors occurred during update The attempted operation did not produce a meaningful result. Try with different inputs. Try decreasing bend radius Feature Compute failed.
My guess is the end points of the arcs are not defined correctly but I do not know how to fix. I have attached the file.
