A generic system has been developed for the geometric design of highway retaining walls. Merging the three-dimensional coordinate geometry capabilities of the roadway design system (RDS) and the drafting capabilities of Intergraph to create computer aided designed and drafted plan sheets has been accomplished. The system operates on the VAX 11/785 and has been used to generate 79 plan and detail sheets of highway retaining walls for tollway projects in Dallas and Houston, Texas. The computer aided design and drafting system has reduced engineering and drafting manhour requirements while at the same time increasing drawing quality and reducing revision time.
