Week 8 - Challenge 4 - Bumper

AIM: to make a model from the provided class-A surface.

CLASS-A SURFACE:

FOR DRAFT ANALYSIS:

First we analysis the model and then choose dummy axis in x and y direction.
As we intersected to proceed we observed that the side walls are not given any draft. Hence we assume the axis normal to the base surface and parallel to side walls. This surely will create problems because a minimum draft has to be provided.
As class-A surface is made by other designer only he is authorized to make changes, so we look over this to complete the coin holder for practice.
Now we go to insert< analysis< draft analysis and follow usual procedure to do the analysis.
Align the compass and click on the surface and as expected the model is mostly in red color i.e. negative draft with respect to the axis.
To correct it to as best as we can we moved the compass a bit till we got most of the surfaces in green and lock that position.
After hitting ok, we change the direction of the line from z axis to compass direction. The axis will align itself accordingly.
