Its not really relevant what reasonably intelligent people make of the 'law'....
WE know that you CAN NOT take a pdf of a 45 year old technical drawing, tolerances detailed or not, or even a CAD file of an elevation/s - and directly CAD/CAM a product, we KNOW THAT......
but the words read as they read;
51F Possession of digital blueprints for manufacture of firearms
(1) A person must not possess a digital blueprint for the manufacture of a firearm on a 3D printer or on an electronic milling machine.
Maximum penalty: imprisonment for 14 years.And the definition is not ambiguous at all....
digital blueprint means any type of digital (or electronic) reproduction of a technical drawing of the design of an object.But possession is possession right?;
possession, of a digital blueprint, includes the following:
(a) possession of a computer or data storage device holding or containing the blueprint or of a document in which the blueprint is recorded,
(b) control of the blueprint held in a computer that is in the possession of another person (whether the computer is in this jurisdiction or outside this jurisdiction).As per all other provisions of firearm law, the police will not interpret the law, THEY TAKE YOUR GUNS, " 'cause theyre just doing their job"... the good luck, in front of the Mag, He/She is the only one who will decide on the interpretation.... In the mean time it would cost you lots of money, time and heartache in defending your self and regaining your licence and firearms....
Note:
They even accept that the offending file might be OUTSIDE of their jurisdiction....! I guess they'll have to extradite the offending bits
Seriously though, this law is highly offensive to liberty, freedom.... prohibited computer files

I can see the metadata used to target individuals who 'frequent' various DIY websites containing the files, then the police giving the masterkey a run, with the AR15/MP5 squad in tow....
