Week 8 - Challenge 4 - Coin Holder Design

Draft analysis is procedure to make sure that appropriate drafting angles are given to the faces which need clearance while tooling.It's such an important validation to carry upon since improper draft angles can create deformities like flash which creates failure,unwanted friction on the material thereby causing material wastages etc.

In Catia,draft analysis is performed using draft analysis command. It helps in validating the face angles.There are some default colour code that represents the draft angle range.

In the coin holder challenge,a tooling axis is created through a centre point on the base surface on y direction.

The bisecting method is not used in this particular challenge. The intersection of the class A and yz axis is taken to create a reference point to create the tooling axis.

The bisecting line method is generally helpful inacase the drafting angles given to the faces are unequal and to create a common line for those faces.

It identifies a point which would be the intersection of the given two lines and craetes a tooling axis from that point in the required direction.
