Week 11 - Project - A pillar Design with Master Section

Objective: The main objective of this challenge is to understand the given master section to create a solid body and B-side features for a given class A surface, by considering all the design parameters.

Master Section: Master sections are the guides for design requirements which decide the component packaging after technical (Styling, Concept or Class-A) surfaces.

Tooling Axis creation:

To create the tooling axis, I used the 'bisecting' line method. Initially, I created two lines on the master section by using 'point to point line' and then I created a bisecting line at the centre of those two lines by using bisecting line option in the line command.

Point to-point lines on the master section

Draft analysis for class A surface:

The craft analysis check is performed on the class A surface before we create the solid part from that class A surface, to check whether the given class A surface is drafted properly or not. The draft angle for a plastic component is 0.5deg to 3deg).

In the above image, some faces on the class A surface are not clearing with a 3deg draft angle. I reduce the draft angle gradually to clear the faces which are not clearing with 3deg.

The all surface are only cleared with 1.9° Draft

Class B surface creation:

To create the class B surface initially, I measured the thickness of the master section (2.5mm). I offset the class A surface 2.5mm to the inside direction. The styling fillets on the class A surface are not offset properly, it created the patch on the offset surface. I used the sweep command to close the patch on the offset surface.

Class C surface creation:

To order to create the class C surface, I used the sweep command. I sweep the class A surface edges along with referencing the surface for 4mm inside with 90deg. After the creation of the class C surface, the surface edges are needed to be extrapolated to intersect properly from all 4 sides. I trim the surfaces which extrapolated, to get the closed class C surface. I joined the class A surface and Class C surface to get a single surface of class A+C surfaces. I trim the Class B surface with class A+C surface join, to get the closed surface to create the solid body.

Solid part body creation:

To create the solid part body, 1st i make it close body with A,B and C surface trim together to get closed body.

Dog House creation:

1st i projected the master section and pad with thick surface of 2.5mm already it have darft but i make side core axis and draft at the inside area.

In my next step i make the inside rib for the dog house for that a projected the master section into sketch and pad it and uniontrim with the dog house body
