Computer-Aided Design Systems Applied to Ship Piping Design.

摘要

Three generations of computer assist to piping: batch systems, interactive drafting systems and interactive design systems. Characteristics of batch systems are record input, cumbersome editing, piping database and inflexible output. Characteristics of interactive drafting are easy editing, archive quality plots, line-on-paper database, limited data capture and limited 3-D capability. Characteristics of interactive design are easy editing, true 3- D, generalized database, output report language and design rules checking.
