I started to make design that 3d model in Rhino 3d 5 . I use Vray 3.0 for render engine. It was a good work . Each modeled surface was analyzed. I have recorded in about 14 formats and I have opened and examine the model in every 3d program.It opens up smoothly in every program.There is no deterioration on the surfaces. I opened the 3d model in each program and then I got a screenshot. Please look through the photos carefully!!!
Have a Good Dowloading! :)
Model Features ;
2.1.1 Lifebuoy specification
Every lifebuoy shall: .1 have an outer diameter of not more than 800 mm and an inner diameter of not less than 400 mm; .2 be constructed of inherently buoyant material; it shall not depend upon rushes, cork shavings or granulated cork, any other loose granulated material or any air compartment which depends on inflation for buoyancy; .3 be capable of supporting not less than 14.5 kg of iron in fresh water for a period of 24 h; .4 have a mass of not less than 2.5 kg; .5 not sustain burning or continue melting after being totally enveloped in a fire for a period of 2 s; .6 be constructed to withstand a drop into the water from the height at which it is stowed above the waterline in the lightest seagoing condition or 30 m, whichever is the greater, without impairing either its operating capability or that of its attached components; .7 if it is intended to operate the quick release arrangement provided for the self-activated smoke signals and self-igniting lights, have a mass of not less than 4 kg; and .8 be fitted with a grabline not less than 9.5 mm in diameter and not less than 4 times the outside diameter of the body of the buoy in length. The grabline shall be secured at four equidistant points around the circumference of the buoy to form four equal loops. 2.1.2 Lifebuoy self-igniting lights Self-igniting lights required by regulation III/7.1.3 shall: .1 be such that they cannot be extinguished by water; .2 be of white colour and capable of either burning continuously with a luminous intensity of not less than 2 cd in all directions of the upper hemisphere or flashing (discharge flashing) at a rate of not less than 50 flashes and not more than 70 flashes per min with at least the corresponding effective luminous intensity; .3 be provided with a source of energy capable of meeting the requirement of paragraph 184.108.40.206 for a period of at least 2 h; and .4 be capable of withstanding the drop test required by paragraph 220.127.116.11. 2.1.3 Lifebuoy self-activating smoke signals Self-activating smoke signals required by regulation III/7.1.3 shall: .1 emit smoke of a highly visible colour at a uniform rate for a period of at least 15 min when floating in calm water; .2 not ignite explosively or emit any flame during the entire smoke emission time of the signal; .3 not be swamped in a seaway; .4 continue to emit smoke when fully submerged in water for a period of at least 10 s; .5 be capable of withstanding the drop test required by paragraph 18.104.22.168. and .6 be provided with a quick-release arrangement that will automatically release and activate the signal and associated self-igniting light connected to a lifebuoy having a mass of not more than 4 kg. 2.1.4 Buoyant lifelines Buoyant lifelines required by regulation III/7.1.2 shall: .1 be non-kinking; .2 have a diameter of not less than 8 mm; and .3 have a breaking strength of not less than 5 kN.
