I have a sandwich of materials of different materials and hence different colours and wish to make a hole through them. For an example i have a sandwich of three sheets of material, red, green and blue through which i want to make a hole.
I create the three sheets, as boxes, on one layer and change the colour property of the layers to red, green and blue. I then create a cylinder. The model is shown as, "basic sandwich plus cylinder".
I undertake a boolean subtract of the cylinder from the three layers and the result is that the three sheets become one one blue solid with a silver hole, the colour of the cylinder. See "Sandwich with hole". From searching the web this is what i would expect but is not what i want.
I want the three sheets to retain their own properties and the hole in each to be the colour of the sheet.
The work around i have is to create three cylinders each the same colour as one of the sheets and undertake three boolean subtracts.
The problem i have is greater than this as i have an array of say 30 holes through a sandwich of five different materials. My work around takes ages as i have first to copy the array to the same location 4 times, explode the array, and then perform 150 boolean subtracts!
There must be a simpler solution as in the aerospace industry this must be a daily task.
Any help appreciated.
Bob

It was made that way if you use SUBTRACT.
To get around this, you explode the cylinder to get a surface, then use command SLICE and pick the Surface option, this way the sheets still remain separated.

Can you create
1 box
1 cylinder and array the cylinder
Subtract
Slice the box into layers?
Or simply create a thinner box and copy it after "drilling"?
I suspect your layers must be something more complex than the example you attached here.

I doubt that the aerospace industry is using AutoCAD for this.
Since I have brought up the topic of software used - this is trivial in Autodesk Inventor.

Thanks for the speedy reply.
I exploded the solid cylinder and sliced it twice at the level of the junction of the three sheets.
How do i them make the hole using the sheets and the sliced surface of the cylinder?

i tried your method but the array cannot be subtracted and has to be exploded first and if do I still get silver holes inside the coloured sheets.

Slice, pick all three sheets, then S for surface,pick the surface of the cylinder, enter, pick the sheets, and move the punched out parts.

Autodesk Fusion 360 is very very inexpensive (not sure how it would do with this problem though.
But I have to imagine it would be easier than AutoCAD.
