I need help with this!

[Anonymous]

OK, here is the deal. We use laser cutting machine to cut more complicated
sheet metal parts (sometimes simple ones too?). We are fabricating louvers
by cuting and then bending each individual louver on the RAS folding
machine. I did most of it on this part but I dont know how to make those
cuts for louvers. I will post both my IV part and ACAD drawing
(customer-files) to show how it looks.
It is probably not a big deal for some of you but I am using IV only for
about month or so...

Thanks

To model this use the louver iFeature. Inventor however won't be able to provide a flat pattern of this type of feature. To build the part a drawn louver is more of a slit in the metal, looks like you may be attempting more of a lance feature that simulates a louver. In any event I don't think I can give you much input on the correct geometry to burn into the sheet.

Your laser cutting must take out some material, so you have to duplicate that. Offset
your existing sketch lines and make closed surfaces, to cut out martial with, then use the
Bend tool.

I think that this is what you are looking for.
Offset the width of the laser beam itself making sure to close off the ends and use the cut feature to remove the material as shown in the reply I sent on the post site. Same holds true for CNC punching machines. You have to remove the material that the punch is going to take out.
I hope that this helps.

I knew about iFeature, but it needs to be burned
into flat pattern. Like Kent and Tom suggested offsetting line for laser beam
thickness (.010), closing the loop and then cutting it is maybe the only
option.

Laser will run the whole loop on the sheet though,
unless dxf file is edited prior converting to machine code (thanks
Tom).

Thanks everyone
