DESIGN with TurboCAD

Lately I've seen a lot of HULL designs an all forums. Unfortunately all are photos of some plans and when I tried to increase no longer understand anything of them because the distance between points becomes very large and design becomes unreadable.In other words or the picture must be done close to a high-performance device (8-10 mega pixels), or to appeal to a specialized program design.
I try to draw with TurboCAD submarine hulls.Has anyone experience with this program or another?.
I know maybe is not the best or complex program to do that but is all I can get so...
Can some on share their experience regarding these issue?.

HI,
NOBODY use ANY program?!.

I am rather ashamed to say that the only software I use is a very elderly version of Paint Shop Pro.

I use this on scanned jpg drawings. It gives me accurate coordinates on-screen and I can print out full size frames etc on A4 paper.

I haven't felt the need to go onto 3D rendering etc. because that is the next step in producing a male mould anyway.
