How do I do this in sheetmetal?

[Anonymous]

Hello,

I need to make a sheetmetal part (from 0.035 Stainless
Steel) which is a long rectangular sheet (about 3 by 22
inches) with a long rectangular slot (about 1 by 12
inches) centered along the length, and then the sheet
bent with a 4.5 inch radius into a U-shape. This item
will be the side of a chamber, and the slot will be
a window into the chamber.

I have started with creating the U-shape bent sheet
by creating the two legs of the U and then adding a
'full-radius' bend between them to create the curve
of the U. This works fine.

Now how do I put in the slot? It does not seem to
be something that I can draw onto a plane and then
project onto the curve of the U and get what I want.

I was going to draw the profile of the slot and sweep
it around the U, but the sweep command does not seem to
be available.

What I would like is to draw this sheet as a flat
pattern and then have Inventor bend it!

Thanks for any help,

Scott

When you sketch, project the FLAT PATTERN and make
your cut with the CUT ACROSS BEND option.

Does that work?

Start with the piece flat with the slot in it, draw a bend line on the part,
fold it 180° with a bend radius of 4.5.
