How to draw segment elbow 90 degrees and create Flat Pattern ?

Hi,

I would like to know how to draw segment elbow 90 degrees ( segments are not equal ) and create Flat Pattern for each of the segments - using sheetmetal in Autodesk Inventor?

Please always include the Inventor version you're working in.  If I produce a 2013 solution, will you be able to open it?

Can you attach the ipt file of what you attempted.

Search here on sheet metal gore(s) might turn up the solution.

 

Trimmed surfaces and Thicken.

I would create the surface model and then Derive Component into each gore part to Thicken and Flat Pattern.

Hi Sam B, I am using Inventor Professional 2013 - 64 Bit.

Hi JDMather, here I attach ipt file that I attempt to draw.

Hi TheCADWhisperer,

it works good! How did you make it?

Please explain the steps.

How to split each segment ?

You can find this out for yourself by examining the files.  Open Gore2.ipt, for example, and notice that it is a sheet metal part with only one feature: a derive of Elbow Master.ipt.  Right click on this feature and choose Open Base Component.  This will open the file Elbow Master.ipt.  Now pull the End of Part marker from the bottom of the browser to the top (everything disappears).  Now pull it down one step at a time and examine what TheCADWhisperer did at each step.  If there's anything you don't understand, just ask here.  But you'll learn a lot more by trying to figure it out for yourself.

Hi,

 

That is a good way of doing it and I am sure it would be within manufacturing tolerances but a big issue in modelling this type of ducting is the interference problems between adjoining sections of the "lobster". (Simply zoom in and you will see that all the sections interfere.)  To avoid this, the op could specifiy a small angle between parts in the skeletal sketch (on the interior side) or use a program like duct pro for inventor.  It is cheap and will pay for itself in no time even if you only do ducting like this once in a while as I do.  (I am not associated with duct pro in any way.)

@TheCADWhisperer / Sam B,

After Sweep Surface, how to trim surfaces because I have no workplane ?

Please advice.

 

@RobJV thanks for the information.

What do you want to trim?  You've got the surfaces you need, now thicken them individually into separate solids.

What are you trying to trim (can you post screen capture of trim from the example file)?

 

You can use a simple line on a 2D sketch to trim or use the line to create a workplane.
More information is needed on what you are trying to do.

Are you trying to model the perfect parts with no intersection?

Will you be making these parts in-house or sending out to a vendor for manufacture?

What is the manufacturing tolerance?

How will the individual gores be assembled?

Sheet metal like this usually has liberal tolerances and the slight intersections in this technique might not be of enough significance to worry about.  Check with the fabricator out on the shop floor to see if the solution will be good enough.

@Sam B : I've  thicken them individually, but how to make separate solids? ( how's the next step ? )

Please see the attachment.

 

@JDMather : I just want to do what TheCADWhisperer did. ( not making perfect parts with no intersection )..Smiley Happy

Use the New Solid button in the Thicken/Offset dialog box.  You can go back and edit your Thicken features as shown:
