So far, the best "general" drawing package I've encountered is Aegis
Draw Plus. It is a good compromise between features and ease-of-use --
I've seen more-featurefull programs that were too hard to use, and
programs like IntroCAD that are basically useless, they're so simple. 

The only problem is that it's slow as mollasas!

So, does anybody know: 
  Does it use the standard Amiga IEEE libraries?
  Can it take advantage of a CMI board with 68881?

It obviously does floating-point math... which is why it's as slow as
it is. Anybody ever heard of an "integer" draw program which allows
the scalability of a full-fledged package but on an integer basis? I
once experimented with a version of DDA that used only integer math...
it was fairly simple, you just maintain things as dividend/divisor
pairs until you need to plot the actual point.  Or a program that uses
its own floating-point format that's faster than usual formats? (for
those of you who've never dealt with floating point before -- division
and multiplication are ridiculously simple, adding and subtracting
require scaling & are thus slower, EVERYTHING is slower if the major
fields are not on a byte/word boundary & are thus difficult to
access).

The 68881 is the preferred solution, of course, but I'm desperate for
just about anything.... the existing draw packages simply are TOO
SLOW, at least what I've seen.
