Abstract: PURPOSE: In applying an asymmetric cowl top cover in the reference of a center line of a wind shield glass, an optimum wiping performance is maintained. CONSTITUTION: Information about glasses are inputted into a CATIA initial screen(S101). It is determined whether a certain offset of a certain area is required in the glass area(S102). A wiping pattern is set by carrying a normal routine when the offset is not required, or the offset is determined when the offset is required(S103,S104). A ceramic area is calculated automatically by the offset, and the area is drawn and displayed(S105,S106). It is determined whether a wiper operation condition is satisfied by inputting information about a pivot position and pivot shaft in the display area(S107). When satisfied, the wiping pattern is produced, and it is determined whether a legal condition is satisfied(S110).
