I have a 2mm-thick square shape that has been extruded 2cm tall. I need to drill holes into each side of the square, in exactly the centre of each side (both horizontally and vertically).
In the past, to create holes, I have just created a circle, extruded it, and then subtracted it from the thing I wanted the hole in. However, that was all done “by eye” - I didn’t need to know if the hole was exactly in the centre or not. This time I do need to get it precisely in the middle of each side of the square.
Could someone please talk me through this process?
