LEDbit2.3dm 2.zip (760.4 KB)I want to cutaway some holes with an arrangement of pins which are instances of a single block. Is this possible? When I try, only the object to subtract from will highlight - the pins will not.
Blocks are not “real” geometry, they are just instances based on an original definition (which could include all sorts of objects) and some sort of transformation. To get at the underlying geometry, you need to explode the blocks. If you want to keep the objects as blocks, explode them first, cmd+C to copy the exploded geometry to the clipboard, cmd+Z to undo, cmd+V to paste the real geometry back into the file. Then do your BD with that.
