Week 9 - Project - A pillar Design with Master Section

CLASS A DRAFT ANALYSIS-

In the above-given images initially, I gave a draft angle of 2.5deg and still some faces are not cleared later I gave a 2deg draft angle to check if all the faces are cleared or not. Still some faces are not cleared with 2deg also, so I reduced the draft angle to 1.9deg, with a 1.9deg draft angle all the faces in class A are cleared properly.

In the Below 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.

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.

I extracted the edges of the patches, to give as a sweep command's guide curves to close the patch.

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, I used closed surface command in the part-workbench. I gave the closed surface as an input in the closed surface command.

Draft analysis for the solid part body:

The draft analysis is used to check the surface draft angel and to know whether all the surfaces are drafted properly or not.

• The draft angle for the solid body of A pillar is 3deg, some surfaces are not cleared properly with a 3deg draft angle. Previously I mentioned in the class A draft analysis report with a 1.9deg draft angle all the surfaces are cleared properly.
• The draft angle for the outer surface of the dog house is 1.5deg.
• The draft angle for the inner surface of the dog house is 0.5deg.

Because of class A surface curvatures and deviations, some areas on the class C surface are not highlighted in green colour.

The below-given surfaces are not cleared properly:
