• 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

• HULL DEVELOPED AFTER FAIRING IN FREESHIP V3.4
• WIREMESH VIEW • SHADED VIEW
⚡ PREPARATION OF OFFSET

• 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
