Can I extrude the union of a rectangular pattern and another sketch shape?

I have an area on several sides of an enclosure box that needs vent holes - but only in specific areas. I have parameters set up that define the shape of the box and the size and spacing of the vent holes, but I need a way to have all of the vent holes, that appear in a specific part of the sketch, extrude through the wall of the enclosure. When I change the parameters for the size of the box, the size of the holes, or the spacing between them, I want the vent holes to update to fill the space defined by the enclosing shape. I'd very much hoped that I could create a rectangular pattern that only extended to the border of the enclosing shape, but that doesn't appear to be possible.

 

For a static object (one that I don't intend to be messing with the size of the box, holes, or their spacing) I'd just manually select each hole by hand to do the extrusion. That's going to be an issue with a parameterized design, though.

 

In the screenshot, I've made the rectangular pattern huge enough that it completely overlaps the circle. I'd like the vent holes to extrude through the wall of the box anywhere inside the circle. Preferably, partial holes would be possible, but that's not critical.

 

  Thanks.

Fusion 360 does not like a great deal of sketch patterning so I think you will have better success and control if you create one parametric component which used solids and the Combine - Intersect command.  You would then take this component and insert it into your assembly, break the link which will automatically carry the component parameters into the assembly.  You could then Copy and Paste, do not use Paste New, the component into all desired areas of your assembly and use Joints to hold it in place.  Using the parameters you could then adjust the vent pattern as desired.  This method accomplishes what you mapped out in your question plus it is very portable.  My parametric vent hole component example is attached.

Sort of or within reason.

I started with 120 mm hole, and the file updates between 110 and 135 mm.  I imagine that you will have a small range and not like half size or double size.  If so you would have to reselect the feature selections.

I have not done much with the Web command, but it might get you there as well (modelling the dividers and not the holes).
