• IMPORTING OF OFFSET INTO

MODELMAKER

• FAIRING OF THE

HULL AND EXPORTIN

G OF OFFSET

• VIEWING THE

STATION AND

CORRECTING ANY

ERRORS IN OFFSET

• PREPATION OF THE OFFSET

INTO REQUIRED FORMAT FOR MODELMAKER

• IMPORTING OFFSET INTO FREESHIPV3.4

• EXTRACTION OF OFFSET

• PREPARATION OF OFFSET

TABLE

• VIEWING THE GF FILE IN GF

VIEWER (DEADWEIGHT)

• BASIC FLOW CHART

⚡ EXTRACTION/PREPARATION OF OFFSET

BODY PLAN USED TO EXTRACT OFFSET TABLE

• USING THE LINEAR DIMENSION FUNCTION OF AUTOCAD,THE DISTANCE OF EACH STATION FOR A FIXED WATERLINE WAS FOUND FROM THE MIDSHIP AND REPEATING THE PROCESS FOR EACH STATION ,THE OFFSET TABLE WAS MADE

⚡ EXTRACTION/PREPARATION OF OFFSET

© VIPIN DEVARAJ, DEPARTMENT OF SHIP TECHNOLOGY,CUSAT

• OFFSET PREPARED IN MICROSOFT EXCEL USING THE DATA FROM AUTOCAD DRAWING OF BODY PLAN

⚡ PREPARATION OF OFFSET TABLE

© VIPIN DEVARAJ, DEPARTMENT OF SHIP TECHNOLOGY,CUSAT

• OFFSET ARRANGED IN FORMAT REQUIRED FOR IMPORTING TO FREESHIP V3.4

• THIS IS DONE BY GETTING REQUIRED COORDINATES OF POINTS ON EACH STATION LINE FROM THE AUTOCAD DRAWING OF BODYPLAN

⚡ IMPORTING TO FREESHIP V3.4

• UNFAIRED HULL OBTAINED AFTER IMPORTING OFFSET IN THE REQUIRED FORMAT FOR FREESHIP V3.4

• WIREMESH VIEW

⚡ FAIRING OF HULL

© VIPIN DEVARAJ, DEPARTMENT OF SHIP TECHNOLOGY,CUSAT

• HULL DEVELOPED AFTER FAIRING IN FREESHIP V3.4

• WIREMESH VIEW • SHADED VIEW

⚡ PREPARATION OF OFFSET

© VIPIN DEVARAJ, DEPARTMENT OF SHIP TECHNOLOGY,CUSAT

• CHANGING OFFSET IN REQUIRED FORMAT TO IMPORT INTO MODELMAKER

• COORDINATES OF POINTS ON EACH STATION IS GIVEN,AND A LOCUS OF THESE POINTS ARE DEVELOPED.AN ADDITIONAL END POINT IS ADDED TO COMPLETE THE CURVE
