Week 12:Project 2-Meshing of Rear Wheel Holder challenge

Objective: To extract midsurface and mesh the component and give thickness.

Procedure:

• We should understand the geometry, check for the errors in the parent geometry.
• In this rear wheel holder design, there were lots of missing surfaces, extra surfaces.
• But ignoring those we should directly take the midsurface, by automidsurface or manual.
• I try with automidsurfacing first and if it fails, I go with manual offset midsurface.
• I got the perfect midsurface with the offset only option in automidsurface.

• The midsurface also had missing surfaces and irreggular surfaces because of the parent geometry.
• That were removed using replacing points, adding new surface, building new surface by ruled and then doig surface edit to get desired geometry.

• The toughest part to fix was this one-

• Here, I had to do all these operations- replacing points, adding new surface, building new surface by ruled and then doig surface edit to get desired geometry.
• These surfaces even further distured me during meshing.
• Had to replace points and make the mesh correction manually.
• There were extra surfaces also which had to deleted or points has to be replaced.

• Then we had to remove these buttons because they are very small and would compromise the mesh flow.

• To remove this we can delete surface and then add filer surface and then toggle the line.
• Some missing surfaces had to be filled by a filler surface or by using ruled option.

• After we have completed with the geometry cleanup we can start the meshing.
• I've started the meshing from the center area and this is how we have cleaned the geometry for better mesh.

• Meshing was simple at many areas but equally difficult at some areas as it had many edges.

• Here we replace points by removing the edges and then we rebuild the mesh it goes little off geometry but that's the only way the elements won't fail.

• We stitched points there and then rebuilt the mesh.
• After these edges, there were small topology which was similar to this case.

• So instead of capturing this we stitched the points above and below it.

• The last part was this,

• Here we created points in between and then replaced the points.

• Then check for edges and remove if there are any.
• The final part is to assign property and thickness.

Result and final model:

• By turning on parent geometry and enabling 2d detailed mesh view.
