Week 8 - Challenge 3 - Coin Holder Design

SOFTWARE USED : CATIA

Tooling Axis:

• Intersect the model with the plane perpendicular or to an axis system.
• Extend the lines which are perpendicular to the plane.
• Again intersect the model with another plane and extend the lines perpendicular to it.
• Create a bisecting line by bisecting option in Line definition.
• Rename it as Tooling Axis.

Class B Surface:

Side Walls:

• Extract the side walls with no propagation in  extract option.
• Untrim them.
• Extrapolate the walls with point continuity of distance 20mm.
• Trim the walls to get the required shape.
• Offset those trimmed walls with thickness value.

Top & Bottom Surfaces:

• Extract the surfaces separately and untrim them.
• Extrapolate the surfaces with required distances.
• Offset them with thickness value.
• Trim them for required shape.
• Measure the fillets, calculate it and create fillets.

Class C Surface:

• Get the boundary lines of Class A surface separately.
• Smooth the curves with a smooth option as boundary lines have a lot of vertices.
• Sweep the curves with tooling axis as direction in Sweep option.
• As both lines do not intersect, extrapolate them with a certain distance.
• Trim the surfaces.

Draft Analysis:

• Go to the Insert menu and select the Analysis option.
• Select Feature Draft Analysis.
• Select the Material option and select the surface.
• Drag the compass and place on tooling axis.
• Make sure that the top surface is in green colour as draft angle should not exceed 3deg.
• Click on Okay after confirm the model.

Close Surface:

• Now using close surface option from part workbench form a solidbody from surface body.
