Hello,

First post here so hopefully it works out well. I'm having difficulty with a sheet metal part creating a flat pattern for it. The shape is an ellipse with the dimmensions shown in the second picture. When I attempt to create a flat pattern it just shows the side of the part. The sheet metal defaults are correct for the part and it was ripped to created a base point for the pattern. I need to create a DXF for manufacture. I would just use the flat pattern it gives me and mirror it twice to create a pattern but it doesnt factor in the radius of the part. Any thought on how to create a correct flat pattern for this item?

Thanks

What version of Inventor?

Do not sketch the thickness - Inventor will do that for you.

Only need one ellipse.

Contoured Flange (from the sheet metal tools).

Rip
Flat Pattern.

Thanks for the quick response

Let me give that another try - looks like Contoured Flange won't select an ellipse.   (and you left out some inportant information about the trims)

I have to run - so not time to finish the part, but you get the idea
