Raster-to-vector conversion for free:
I used DesignCAD years ago, first as the DOS version, then as several
Windows versions. Worked very well until the original developers sold
the program, and then became "quirky" to the point of being
non-useable. Newer versions may be better now.
My employer provided and I used AutoCAD/AutoSketch/etc. from AutoDesk
in several versions. Very capable and feature-loaded, but has a VERY,
VERY steep learning curve. Also, it develops an "unusual personality"
when pressed or memory starts to run short (something that costs that
much is not called "unstable" or "quirky").
I've used TurboCAD from version 4, and I currently use v11 Pro, which
has R-to-V conversion built-in. See comments above for AutoCAD. TC's
saving grace is that it costs way less (but still not cheap) and 2D/3D
is bundled and integrated in the Pro version, which makes it a
candidate for home use. I've never had a stability problem, but I
follow the rule of thumb to at least double the manufacturer's minimum
memory spec, plus I always use a fast processor with a high end video
I've tried many other CAD programs, and none were really "crap", just
different, or maybe "quirky in the extreme". The complex programs
require heavy duty computer hardware and complex learning, and the
simpler programs require less complex, but not simple, learning.
