Week 11 - Project - A pillar Design with Master Section

Aim
     The main objective is to create the  A- Pillar with Dog house considering the design rules using the MASTER SECTION & Tooling axis and to perform draft analysis an the solid body.

Contents

• Class A surface with master section (given)

• Tooling axis

               To create the 'Tooling Axis', the given class A should be observed thoroughly, For the given door handle class A,  Y-axis is the best suitable tooling axis, It is decided based on the complete visiblity of the class A. Then using the intersections made by the appropriate planes and the class A, We get a crossection sketch. The dummy axis is drawn on the y axis. Then the lines which are more or less parallel to the y axis are taken into consideration and drawn. By bisecting the two lines ,  As an output The Tooling clearing axis was derived.

• Draft analysis of class A surface

To perform the draft analysis of class A surface, click on Insert  >Analysis  > Feature Draft Analysis

Once the draft analysis toolbar is opened, The compass was selected and placed on the tooling axis, Then go to the display block and select the 'Analysis under the running point' command to check the angle for different sides on the class A surface. The color scale on the bottom visualizes, whether the draft angle meets the requirements or not (3 deg) by indicating the colors Green, Blue and Red.

• Class B surface

    To create the class B surface from the class A, The class A was offset to 2.5 mm as required. There are some of the patches as issues. mostly those patches are from the fillet areas. So i used the Boundary and Multi section comand and sweep to solve the patched fillets by considering the entire class B. After further operations, The class B was successfully created.

  

• Class C surface

     To create a class C surface, I used the sweep command to avoid the continuity issue by considering the outer boundary of the class A surface. In the sweep command > 'with draft direction', select the outer boundary and draft direction, give 3 deg and select the direction to sweep (C surface is parallel to tooling axis) & it was done multiple times , Accordingly the sweep command with reference surface with angle 90 degree was given (C surface is perpendicular to tooling axis).

• Surface output of A- Pillar

   Then the closed surface was created by using the 'Join' & 'Trim' operation consisting the Class A, C and Class B surfaces.

• Solid A- Pillar

     To create the solid A- Pillar, Jump to part design workbench and select the closesurface option in the Surface based feature.

DOG HOUSE CREATION

    After thickening in the part design , using draft tool with 0.5 degree and fillet tool the solid doghouse was created.

Draft analysis of DOGHOUSE

      Using the boolean operation all the part separate bodies are attached to a single part body.
