extruding/pushpull a large array of circles

[pleasehelp]

Hi All,
I need to design a 'stencil' of sorts - but it just needs to be an array of circles separated by a constant distance. its an array of 200 micron diameter circles separated by a distance of 500 microns each (between centers).
Its super easy to make this array, but when I try to 'pull' it into the third dimension, or extrude the array, I get an 'invalid' error. Or the highlighted objects just get 'unhighlighted' (for the lack of a better word) once i hit enter after selecting them all.
Also, I made the entire array into a 'block' of easiness.
Any help is hugely appreciated!
Thank you!

You should explode that block to be able to extrude the circles. This operation isn't accepting block objects - you probably missed the error in command line:

Cannot sweep or extrude an object of this type

To be able to manage them together, may look to GROUP command instead; however after extrusion the grouping will be lost.

Since you are using 2012 the array may be associative (you pick one and they are all selected) so simply explode the associative array and extrude by selecting them all.

Maybe try extrude 1 then array

Maybe try extrude 1 then array

Now there is an idea.
