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?

Best Regards,

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.

Check this example.

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.

Best Regards,

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