Week 12- 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
Lower substrate :
- creation of tooling axis for the all components are desgined in the industry must and should perfrom the draft analysis for easy clearence from the core and cavity
- check visbility of clearance of all the areas for the given class A ensure that creating of tooling axis in that way
- for the lower substrate the below shown pic will clear maxium areas ,so i have in that direction
Tooling axis for lower substrate
- as we know the above fig will clear max area , so create A line normal to surface ,so it is our toolig axis
- consider this line as tooling axis perform drafting on the class A
Creation of B surface :
- first offset the Class A surface for 2.5mm As given in the Master section
- if there is any patches fill the patches and all should be closed
- extrapolite the offseted area for making intersection between Class C for the further stepsF
B surface
Creation of C surface :
- For creating the Class C we need Extracting the boundary of Class A surface and it is make into smooth curves to sweep the curves by using support surface to the 90 degree respectively
Class C
Final Trims to make a Closed Surface :
- First trim Class B with class C and then Join with the Class A to make the closed surface
- By applying the closed surface we will from a closed body

Tree structure of Lower substrate
ARM REST :
- First extract the base and create the point at centre,take the line with normal to surface and it is our main tooling axis
- for the arm rest component will not clear with one tooling axis , so that we should create B side tooling axis for making clearance between caore and cavity
-
Main tooling axis
Side core Tooling axis
Creation of B surface :
- For creating B surface for Arm rest is somewhat difficult , for that first we want to offset the for Class A surface and it will provide Patches while offsetting
- Fill the patches by Multiple extract and should make the single Class B surface
- extrapolit the B surface for making the intersection between the class C surface in the further steps
Class B surface
Creation of the C surface :
- for creating C surface we want use the Sweep command with 93 deg in respective direction

Creation of Map pocket:
- Check the comdition of Class A then offsetting with 2.5mm and do the filling of patch work with multisection and do extrapolation for intersection between Class B and Class C in further
- then create the tooling axis with normal to surface and perfrom the Draft analysis and check whether it clear or not
- then create the C surface by sweep command with 93 deg
- trim class b with class c and join with class A for closed component

Bottle Holder :
- Check the comdition of Class A then offsetting with 2.5mm and do the filling of patch work with multisection and do extrapolation for intersection between Class B and Class C in further
- then create the tooling axis with normal to surface and perfrom the Draft analysis and check whether it clear or not
- then create the C surface by sweep command with 93 deg
- trim class b with class c and join with class A for closed component
