Sheet Metal

[sergej_dezelak]

I have problem with sheet metal.

In attachment is sketch, that I need and Flat Pattern. The problem is that I need at the end Perpendicular rectangle of this plate. So the flanges should be angled or tapered. Is that posible to do in sheet metal?

Yes.

JDMather thanks for fast response.

But how? I have no idea.

Attach your *.ipt file here.

As it is now, I have no idea what version of Inventor you are using.

[sergej_dezelak]

I am using Inventor Professional 2015.

Here is the ipt

[JDMather]

Here is one possible solution.

Probably an infinite number of solutions - depending on what you really want.

[sergej_dezelak]

No that is not what I need.

I need what I have already, but only Flat Pattern need to be correct rectangle, where it is bend it has to be angled.

Flat pattern is correct for the part you modeled?

[sergej_dezelak]

No Flat pattern is not correct. Outer shape it should be perpendicular rectangle.

Sergiej,

on rectangular sheet metal draw a folding line,

and use command "Fold" (twice)

Uziemblo_U,

If I will use fold than when I make Flat Pattern it will stil not be a rectangle ant the end.

[JDMather]

Something like this?

[Uziemblo_U]

"Fold" command do not add or remove material

your first base rectangle is your flat pattern

you only folding sides

I need something like this at the end when I create Flat Pattern. I draw this in AutoCAD.

I think this with Lofted Flange could be a solution.

Uziemblo_U,

I am not sure that this is possible with using Fold command.

Note that the Lofted Flange flat pattern is not perfect rectangle, but I was too lazy to bother with Fold since it looked close enough for sheet metal tolerance for me.  But Fold should work as well.

Sergej,

it is exactly what I said,

1. Draw base rectangle of your flat pattern

2. Draw first folding line exit skech and "fold"

3. Draw second line and fold....

uu..

[sergej_dezelak]

Yes Fold is the best option, I try it and its working.

Thanks for the solution.
