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
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
CREATION OF TOOLING AXIS – BOTTLE HOLDER
- Add bisecting line by the reference of tooling facing x direction and tooling facing y direction and named as tooling axis
CREATION OF TOOLING AXIS – ARMREST
CREATION OF TOOLING AXIS – UPPER SUBSTRATE
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
I 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

DRAFT ANALYSIS REPORT OF CLASS A – LOWER SUBSTRATE
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
LOWER SUBSTRATE CLASS C SURFACE
BOTTLE HOLDER CLASS C SURFACE
ARMREST CLASS C SURFACE
UPPER SUBSTRATE CLASS C SURFACE
CREATION OF B SIDE ATTACHMENT FEATURES
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
- Trim the portion to get the required sketch
- Draft to 5 degree along second tooling axis
- Add fillet to all faces
- Assemble the doghouse to lower substrate solid
- Translate the doghouse to wherever we need
- To place pushpin on the doghouse create a ribs to doghouse
- Trim the ribs with doghouse
PUSHPIN
HEAT STAKES
Heatstakes is known as thermoplastic staking is the process of joining two dissimilar metals together
- Extract the surface that we going to create heat stake
- Use positiioned sketch and draw a heat stakes sketch
- Use pad commands for the sketch to till we required
- Draft the stakes minimum of 0.5 degree
- Add fillet 0.5mm o all faces
- Assemble the heat stake to lower subtrate solid
- Maintain a 50mm minimum between two heat stakes
- Translate the heatstakes to wherever we need
- Trim the all heat stakes with lowersubstrate solid
LOCATOR
- Extract the surface that we going to create locator
- Use positiioned sketch and draw a locator sketch
- Use pad commands for the sketch to till we required
- Draft the locator for minimum of 0.5 degree
- Add fillet 0.5mm o all faces
- Assemble the locator to lower subtrate solid
- Maintain a 50mm minimum between two locator
- Translate the locator to wherever we need
- Trim the all heat stakes with lowersubstrate solid
- Maintian a height more than heat stake
FLANGE
Create a flange for attachment of heatstakes and locators at lower substrate

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
