Having just got a 3D printer I thought some people might be interested in the possibilities.
I have been practicing with Fusion 360 which is a top end 3D drawing package made available to students and hobbyists for free.
If you plan on getting to grips with this its not like most packages we are used to. Have a look on YouTube at an excellent series of lessons by Paul McWorter called "Learn Fusion 360 or Die Trying". He is an excellent teacher. I used Fusion 360 to draw the compass binnacle, Throttle and joystick for the flying bridge. The photos show my efforts. They are my first attempts and are not touched up in any way yet.
While Fusion 360 is good for cad type drawing when it comes to something like a model lifeboatman another excellent free package is Sculptris. This is very much like moulding clay. Again there are good instructional videos on You Tube.
I am blown away by the quality of both Fusion 360 and Sculptris seeing as they are free.
Using Sculptris I managed to modify a simple sample figure to represent a lifeboat man. The picture shows what I got . I think i can do better having done it once. The items in the photo need improving by a bit of fettling but I am encouraged by my initial foray into 3D printing.
