Week - 4 - 2D meshing for Plastic components

Aim of the challenge:

• Perform topology geometry cleanup errors.
• Creating mid-surface for plastic model
• Assign thickness for each PID part
• Meshing of 2D surface with required quality criteria.

Geometry cleanup:

After geometry cleanup

Select each PID region and assign thickness using weldspots and measuring tools

Make midsurface of each given thickness parts usinng offset command and mid surface and middle tools in topo module.

Middle mid surface

using curves for mid surface

Finally make mid surface for all the parts

Assign thickness for each PID part

Check geometry cleanup for mid surface

Give mesh quality criteria for the given mid surface

Ignore the mesh forms at triple cons formation

Assign solid shell to the mesh component to make it 3d model mesh

3d mesh body

conclusion:

• Mid surfacing of given plastic model of different thickness
• Importance of midsurfacing for complex plastic models and variable thickness
• creating segments and assign different thickness
• It is difficult to make meshing at triple cons.
• tria percentage is 3.99
• It is important to check after mesh with solid to compare with original geometry.
• Thus the given challenge helps in understanding of mid surfacing of complex geometry like plastic bottle cap and also meshing.
