JPH0668189A - Method for automatically applying line number and terminal code in cad - Google Patents

Abstract

PURPOSE:To improve the quality of drawing by automatically applying line numbers in circuit units. CONSTITUTION:Drawing information is read from CAD drawing database in step S1. A wire bound point retrieves one symbol from the read information in step S2. When the retrieval result is ended, the drawing information is written in the database. If the result does not end, the initial value of the line number is updated in step S4 and the symbol of opposite connection is retrieved in step S5. If the retrieval is ended, the processing advances through step S6 to step S7 and the line number is automatically applied.
