ABSTRACT

A draw package is a computer program that allows a user
to  create  accurate  drawings  in a structured format.
This  essay  defines what a draw package is and how one
differs   from  programs  such  as  paint  systems  and
Computer Aided Design systems.  The differences between
two dimensional and three dimensional draw packages are
also explained.

A  number  of  selected  packages are introduced which,
through  various techniques, have increased the ability
of  a  user  to  construct  constrained drawings.  This
survey  outlines  a  representative  collection of draw
packages.   As  well,  current trends in improving draw
systems are listed.

The   proposed  and  partially  completed  multitasking
implementation  of  an interactive two dimensional draw
package   is  described.   The  design  is  capable  of
producing  high quality images in a format suitable for
display  on many output devices.  The implementation is
part of the Adagio workstation.
