Old Rusty Metallic Safe
Are the fittings working functional ?
The fittings, like unlocking wheel, numbers plates and door, are attached to empty curves objects, which let's you rotate and handle the objects. E.g. rotating the Rotation Wheel Handling objects rotates unlocking wheel and in addition moves the security bars.
Is this safe a solid piece ?
Yes, the safe is solid, but not "a single piece". It's build from several objects for the body, the door, the hinges, the security bars, outer security plates, etc. You can remove, add and edit the objects you want.
