Geometry cleanup and extracting mid surface of a plastic model

Question

Clean up Geometry of the following component.

Note: For the component below 6mm thickness, extract the mid-surface for meshing. Attach the hypermesh model files (.hm) with the challenge

Your Answers

Objective: Geometry Cleanup of housing

1. Import the geometry into the Hyperworks using the import geometry window.

2. Change the geometry colour mode to Topo

3. Now open the visualisation pannel and inspect the error in the geometry

4. Use quick edit menu to cleanup the geometry

5. Using toggle edge and replace point command for this cleanup

6. Here is missing surface so deleting the surface and crating the new one

7. Use fillet surface command for this surface

Objective: Geometry cleanup of the plastic model and later extraction of midsurface

1. Impot the geometry in the Hyperworks from the Import geometry window

2. Change the geometry colour mode to Topo and open visualisation window

3. Using various tools from the quick edit menu and other features for creating surface, such

errors were easliy resolved

Deleted the surface and created the new one

Deleted the surface and created the new one using the filler surface option

First used the releaase point option then deleted the surfaces with error and then created the

new surface using the ruled option

Deleted the surface and created the new one using the filler surface option

Here is the missing surface

Creating the surface using the ruled option

Note: Here the various lines were toggled which were cless than 1unit apart, distance between

2 points was used to meaasure the distance, hence completing the cleanup process thereafter.

Material and the property were also added into the model.

Objective: Creating midsurface for the same plastic model

Here we used the skin offset option and then auto midsurfacing was done for the whole

geometry at a time

The midsurface thus extracted was manually inspected and then cleaned as sone for the parent

geometry

Conclusion:

Geomerty cleanup tools were explored and were hands on practiced on the 2 different geomertys

Midsurface was extracted for the same geometry and the cleaup was performed on the same as well.
