Hi everyone...

First, sorry for my bad English :o :o :o

I need to measure diferent kinds of accuracy on a cnc milling machine. I know exists a special part or ISO part for this (in Brasil this part are called "nasa" and "nas"), But I don't find the drawing of this. Anyone know as this call? or Send me a copy of this.

Thanks in advance

Fred.

the part is this:
