also got bored and decided to draw this up and render it
That's impressive!
I've d/loaded Fusion 360 but have yet to get a chance to play - I suspect it's going to be above my capabilities......
i have registered fusion 360 now, find it fairly simple to use as long as you know what order to do things in. actually managed to draw up a little fixture i have wanted for a while for compressing the spring in an air rifle to safely remove it and re-install etc.

it is dimensionally accurate although the head is supposed to look like lead but it looks more like steel which im not happy with. havent played with light settings or anything yet either
it is a very easy program to use. from what i can find, solidworks is for the most part, more logical and easier to use but its expensive.
I built a rig for inspecting 30mm rounds earlier this year; the idea was to track an Eddy Current probe along the round as it rotated on rollers but it was a bit of a pain as the profile of the nose wasn't a constant radius or arc that you could draw easily, I was told it's an Ogive curve, designed by the aerodynamicists.
Quite interesting project in some ways, the rounds themselves are made from a lead-loaded steel alloy.
to draw that .50BMG i used actuall measurements from a once fired case i have here, and then just drew the bullet head to look right based on the diameter of the head and the length after it was seated, so it looks quite like a boat tail ballistic tip but in actual fact the round should have a much rounder nose and a slightly larger radius to the profile...but i couldnt be bothered to work out what it should be so used a 3 point arc and made it look like it could be right lol
If I think on, I'll get some pics of the various ordnance we have kicking around at work... the biggest shell case is the boss's door stop, it must be two feet tall - and brass
We have mortar rounds, APDS penetrator darts, 105 and 155mm tank rounds - not live, obviously, they're all test pieces for machine calibration.
The biggest actual round is an absolute gutbuster to pick up, and that's an unfinished round with no charge, fuse etc., it's used to drill holes in naughty dictators' bunkers
A mate of mine is a diving instructor and several times over the years has recovered unfired ammo from assorted wrecks on the sea floor... I did have a pic of him with a wheelbarrow full of .303 that came from just off the north-east coast.
the only real problem i am having is my laptop isnt man enough to run fusion and anything else at the same time
I think any cad program is futile to use on a low performance computer specifically where rendering the object is concerned.
I remeber the days I used 'Lightwave3d' on an amiga 1200 and it took ages to render a scene,the more you added to scene the longer it took to reneder/

Solidworks really asks a lot of your computer too, i had a pretty decent laptop with solidworks on it and even that ran slow or got stroppy sometimes.

Why render a object? It has merit in a studio situation but for any other time shading is perfectly fine and true rendering is a waste of time.
Solidworks will work on a relatively lowish spec machine for general simple stuff. Complex models is where it starts to hurt and you can only go as far using the fasted E5 processor, actual number of cores doesn't matter as it doesn't multi core process much so it would be one of the E5-16XX on v3 now. High i7 processors aren't far off E5.
Thing is with graphics, the expensive CAD graphics cards aren't very good value (about 3x the cost of the equivalent powered gaming card often) but ............what you pay for is the specific CAD drivers more than anything else which makes the big difference. The graphics card companies have made it impossible to load CAD card drivers on gaming graphics cards for some years now to protect the CAD card products.
i render things because when i used to make parts for people like air gun accessories they were often ade of multiple materials, and often had a movement action such as a sliding safety pin, or a rotating magazine so when someone said can you make this i could draw it up and send them a file or animation showing exactly what it would look like and how it would work etc. it was never high quality stuff but far better than a message saying 'yeah i can probably do that'
