Week 11 - Final project
AIM
To create a door interior part from the inputs of class A surface along with master section by following the design rules followed in tier 1 and OEM industries in catia v5
SOFTWARE USED
CATIA V5
OBJECTIVES
• Create a sketch by using Positioned sketch
• All the should be sketches should be
Iso-Constrained • Ensured Proper Tree Structure
• Geometrical sets should having a proper name based on the sketches
present inside of it • Create thickened part using master
section for reference
• Create the mounting features as per design guidelines in the industry and with master sections
Creating of Draft analysis & Tooling
analysis
• Creation of parting lines and check tooling feasibility
INPUT OF CLASS A SURFACE
Since the input class A surface is containing four different parts (class A). So class b and c for all the surface has been created in separate catpart. Also performing draft analysis and tooling axis separately. finally all the surface have assembled together in one catproduct
CREATION OF TOOLING AXIS - LOWER
SUBSTRATE
DRAFT ANLAYSIS
Draft analysis in catia is a command that is used to detect if the part you drafted will be easily removed from the mold. it is performed based on color ranges identifying zones on the analyzed element.
Most of the industries is using minimum draft angle is 3 degree

DRAFT ANLAYSIS
Draft analysis in catia is a command that is used to detect if the part you drafted will be easily removed from the mold. it is performed based on color ranges identifying zones on the analyzed element.
Most of the industries is using minimum draft angle is 3 degree
PROCEDURE
• Check all the boundary whether it has connected or not.
• Check the model visually & choose the best tooling direction which should be easy for draft.
• After analyzing the above model the best tooling axis is y direction.
CREATING THE TOOLING AXIS
• Create a point on centre of gravity of part by using measure inertia command and insert a axis system on the point as shown below
• create a point -direction line parallel to the y axis and named as TOOLING AXIS у as shown below
CREATION OF TOOLING AXIS - BOTTLE HOLDER
PROCEDURE
• Check all the boundary whether it has connected or not.
• Check the model visually & choose the best tooling direction which should be easy for draft.
• After analyzing the above model, we have to create tooling axis on Y
CREATING THE TOOLING AXIS
• Create a point 1 and insert a axis system on the point 1 as shown below
• Create a intersection on XY plane for the given surface
• Create a point to point line as shown
below
• Add bisecting line as shown below by the reference of two lines created above and named as TOOLING FACING X DRIECTION
CREATION OF TOOLING AXIS ARMREST PROCEDURE
• Check all the boundary whether it has connected or not.
• Check the model visually & choose the best tooling direction which should be easy for draft.
• After analyzing the above model, there is an chance for undercut when we consider tooling axis from z.so we have to create tooling axis on x,y and also z
CREATING THE TOOLING AXIS
• Create a point and insert a axis system on the point 1 as shown below
• Create a intersection on ZX plane for the given surface
• Create a point to point line as shown below
• Add bisecting line as shown below by the reference of two lines created above and named as TOOLING FACING X DRIECTION
• Create a intersection on ZY plane for the given surface
• Create a point to point line as shown
• Create a point to point line as shown below
• Add bisecting line as shown below by the reference of two lines created above and named as TOOLING FACING Y DRIECTION
• Add bisecting line by the reference of tooling facing x direction and tooling facing y direction and named as tooling axis
CREATION OF SIDE TOOLING AXIS Y
• Create a point on surface and create a line using point direction, use direction as y axis.
• Drag a compass and place it on axis that we created. Adjust the compass till we get correct view. lock the orientation of the compass.
Modify the above line by changing the
direction along compass
CREATION OF SIDE TOOLING AXIS X
• Create a point on surface and create a line using point direction, use direction as y axis.
Drag a compass and place it on axis that we created. Adjust the compass till we get correct view. lock the orientation of the compass.
• Modify the above line by changing the direction along compass

PROCEDURE
• Check all the boundary whether it has connected or not.
• Check the model visually & choose the best tooling direction which should be easy for draft.
• After analyzing the above model the
best tooling axis is y direction.
CREATING THE TOOLING AXIS
• Create a point on centre of gravity of part by using measure inertia command and insert a axis system on the point as shown below
• create a point -direction line parallel to the y axis and named as TOOLING AXIS as shown below
PERFORMING DRAFT ANALYSIS ON MODEL
• To perform draft analysis open
PERFORMING DRAFT ANALYSIS ON MODEL
• To perform draft analysis open customize view parameters and choose the material
• Insert a feature draft analysis by following these commands
insert analysis>feature draft analysis
Align the compass on tooling axis that we created
Open the color scale and enter the
value is 3 deg.
• If the whole body is green that all the faces is greater angle than the provided angle

CREATION OF CLASS B SURFACE
• Insert a new gemeotrical set.Measure the value of thickness in master section. The value is 2.5mm
• Offset the class A surface to 2.5mm. • Check all the sub elements are formed if not try to fix it locally
LOWER SUBSTRATE CLASS B
BOTTLE HOLDER CLASS B
ARMREST CLASS B
UPPER SUBSTRATE CLASS B
CREATION OF CLASS C SURFACE
• Analyse the class A once where the sweep is easier to create towards tooling direction
• Create a boundary using limitation points whereever possible for sweep
• Sweep the above boundaries for industrial standard 3 degree towrads tooling axis
• Analyse the class A once where the sweep is easier to create towards tooling direction
• Create a boundary using limitation points whereever possible for sweep
Sweep the above boundaries for industrial standard 3 degree towrads tooling axis
• Now Create the c surface by using multisection solid where the sweep cant perform.
• Create a points on the curve as shown
below and Create a line by using point
to point line.
Split the both surfaces by using split command
• Create a boundary by using on the class a surface that is going to pefrom multisection surface
• Join the surfaces by using multisection surface
By using the same method creating the c surface whereever the sweep is not possible
e After join all the c surface
• Using the same method create c surfaces for all the parts

DOG HOUSE
• Extract the surface that we going to
create a dog house
• Insert a axis system. use positioned and draw a dog house sketch
• Sweep the sketch to 1.5 degree on the
direction of main tooling axis
• Add thickness to the above sketch of 2.5mm by using thicken surface
Dog house rule
B=4mm
t=2.5mm
C=0.4* t=1mm
• Extract the sweep and offset to b=4mm and c=1mm on all directions like the below

CONCLUSION
Thus the door interior part has been created from the inputs of class A surface along with master section by following the design rules followed in tier 1 and OEM industries in catia v5
