Door Arm Rest Week 8 Challenge

Aim: To create a solid for the given model and perform Draft Analysis.

Procedure:

• Open the Generative Shape Design from the Start Menu in software.
• Select the open option from the File menu.
• Select the model and click on Open.

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:

First half:

• Extract the surfaces with no propagation in extract option and Untrim them.
• Extrapolate the surfaces with point continuity of distance 20mm.
• Trim the surfaces to get the required shape.
• Offset those trimmed surfaces with thickness value 2.5mm.

Second half:

• Repeat the First half steps with different surfaces.
• Create a point on connecting surfaces between first and second halves.
• Insert the axis system and that point as origin.
• Intersect the surfaces with the plane.
• Create a tangency line with the curved surfaces.
• Extract the lines by multiple extract options with tangent propagation.
• Select the with reference surface option in Sweep option.
• Select the tangency line as profile and extracted lines as guiding curves.
• Extract the surface in the connecting region, Untrim it.
• Create a line with some angle on connecting surfaces and split it with surfaces.
• Use multi sections surfaces to create a surface.
• Extrapolate the surfaces if they are not crossing each other.
• Trim the surfaces accordingly.

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.

Base:

• Extract the base surface and untrim it.
• Extrapolate the surface.
• Offset the surface with thickness value.
• Repeat the steps for the circular part.
• Trim all the surfaces.

Class C Surface:

• Extract the boundary line of the half part of the model.
• Smooth the curve and Sweep it with the reference surface option.
• Trim the surfaces. Use Blend or Multi Sectional Surfaces for complex surface areas.

Final Model:

• Join Class A & C Surfaces.
• Trim the joined surface with Class B surface.
• Go to Part Design and insert a Body.
• Create a closed surface.

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 it on the tooling axis.
• Make sure that the top surface is in green colour as draft angle should not exceed 3deg.
• Click on Okay after confirming the model.
