ENHANCEMENT OF EXISTING ENGINEERING SOFTWARE. VOLUME NO. 2: UWGRAPH COMPUTER-AIDED DESIGN AND DRAFTING LIBRARY - VERSION 1.0

Recent work by the Wyoming Department of Transportation has shown that productivity ratios greater than 20:1 can be achieved by linking design applications directly with CAD (computer aided design). A graphics library (UWGRAPH) has been developed to facilitate this linkage. UWGRAPH is used in conjunction with a design application which performs engineering calculations and/or creates drawing parameters. UWGRAPH links to three graphic formats commonly used in engineering--DXF (AutoCAD), MICRO-CSL (Intergraph), and GKS (screen graphics)--in one application program. The flexibility and familiarity of FORTRAN is combined with the tools necessary to produce graphics files automatically. The library is based on the graphics entities required for structural drafting. UWGRAPH simplifies and unifies the subroutine calls by combining low-level calls to produce graphical entities useful in engineering drawing, e.g., dimensions, notes, etc. The UWGRAPH scope is directed toward bridge engineering but easily spans other disciplines. This report, Volume 2, includes detailed information on each subroutine used to draw the entities supported by UWGRAPH. These descriptions include the definitions of the arguments, an example of the subroutine usage, and a graphical illustration of the arguments. Compilation instructions are included for using UWGRAPH with Unix and Microsoft Fortran compilers. A short section follows with programming hints. This section outlines the errors which are most common and likely to be made by new program developers. Several appendices are included which outline Architecture, Utilities, Include Files, and Data Files used by UWGRAPH, and finally a paper which overviews the UWGRAPH library is given.
