TOOLING AXIS

   The Tooling Direction is basically the direction that the mold pulls a part. The mold is built in two separate pieces, basically. You have a Cavity         side and you have the Core side. The Core pulls apart from the Cavity and that's the Dye line or the Tooling Direction.

Check for gaps between surfaces for that click on join and then preview.
If theres any gap between the surfaces join them with a maximum tolerance of 0.003 mm 
Extract the boundary and dissemble the boundary.
Find the correct tooling axis where the material don't interfere with the tooling axis and all the elements can be created.
Create an axis system using at the centre of the switch Bezel.

The tooling axis is created for the component by bisecting two axis from x and y planes.

DRAFT ANALYSIS FOR CLASS A SURFACE

The Draft Analysis command enables you to detect if the part you drafted will be easily removed.
This type of analysis is performed based on color ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.

CREATING CLASS B SURFACE

Extract the surfaces from the class A using multiple extract and untrim them.
Use Extrapolate to make sure that all the untrims are properly intersected to trim and offset the surfaces to 3 mm to create the thickness.
Trim the extra surfaces using trim command.
Insert them into new geometrical set and name it with respective part names.
Apply fillets to the model after creating the entire surface.
If the edges are outside the fillet value will be added to the thickness of the component and if the edges are inside, the fillet value will be subtracted from the thickness of the component, for instance the thickness of the component Is 2.5mm the fillet value is 15mm so the outside portion value should be 17.5mm and inner eges should be filleted 12.5mm to get uniform thickness.
Perform trims one at a time so that it will be clear to understand.

COMPLETE CLASS B SURFACE

CLASS C SURFACE

Extract the boundary from the class A surface using boundary command.
Using disassemble tool to divide the boundary as the boundary contains domains.
After getting sweep then trim the output with class B surface to get final output.
