I think I remember Andy Payne (CB author) expressing a desire to write a

future 'professional' version of CamBam. I know he's in the midst of

trying to get back to his beloved Australia from the UK before he

launches on a big efforts like that.



Specifics -- well the thing most CamBam users enjoy the most is its

built-in 2D CAD facilities, with som limited (but still available) 3D

functionality. Drawing 3D within CamBam is mostly a 'trick', but it can

be done by creating 2D shapes and translating them about the axes.



I find that I can design more than 90% of my parts (strictly 'prismatic')

within CamBam as multiple orthogonal views, avoiding all the

importation/interpretation issues that accompany doing the CAD externally

with software that isn't specifically CAM-oriented.



It also has a wealth of integrity checks for shapes and milling paths,

although those are in the form of text messages from a debugging handler,

and not highlighted on the drawing.



It's also relatively bug-free. There are a few known bugs, and Andy

faithfully addresses them in each subsequent update, but there are still

a number of them outstanding, and updates have become less frequent

recently. Generally, though, the bugs are well-known.



CamBam presently has some limited lathe capabilities, with promises of

more complete support in the future... maybe even a lathe-only version.



The user forum is about the most helpful place you could imagine for

sorting out issues outside your normal experience with the package. I

don't know of anyone who's ever been shooed out by 'experts' for not

being of their level. That's unlike a lot of other sites occupied by

self-proclaimed gods who don't seem to be able to come down from Olympus

to help neophytes, except with cryptic references to things beginners

wouldn't know, anyway.



I'd say for most users, CamBam is not only their first CAM, it's probably

their first foray into CNC machining, so there are lots of beginners

there. It's targeted at the small hobby shop. It has utility that

extends past that market, and a price that makes it fun to experiment

with, even if it doesn't suit your needs.

Yes.

I'm addicted to solids and to assembly modeling. I'll started with wireframe modeling (Cadkey and Ashlar Vellum) and I'll never go back to wireframe modeling and wasting time with drawing orthogonal views. You get any orthogonal view for free with a solid model and they are fully associative. Change the solid the views update.
