 The {\bf Pic} language is a TROFF preprocessor for drawing line drawing in UNIX environments.
In this work, a classification of the elements of the {\bf Pic} language is introduced, and a convenient graphical interface, corresponding to this classification,  WD-pic, for {\bf Pic} users is developed in the X Windows environment, using Motif.  WD-pic combines graphics and text building and editing of pictures,
and it produces pictures on a screen and a corresponding internal representation, which is fully compatible with
the {\bf Pic} language. The displayed pictures in  WD-pic are realized partly  with the help of the existing {\bf Pic} compiler and partly with  new code. The original {\bf Pic} compiler's source code was modified and incorporated as a separate process in  WD-pic. Creating pictures in WD-pic was tested and  compared with writing description of the same pictures in the {\bf Pic} language  and creating the same pictures with the help of {\it xfig}.
