Mesh Editing

QuickStart1 guides you through cleaning and optimizing 3D mesh data of an automotive sheet metal part:

The process includes healing mesh irregularities and performing a series of mesh optimizations to the imported 3D mesh.

Modeling Process

1. Click Insert > Import and open SheetMetal.stl at following location: ~/INUS Technology/rapidformXO Redesign/Sample/QuickStartGuide. The model looks as shown below.

2. Double click SheetMetal in the Feature Tree to go to the mesh mode.

3. Click Tools > Mesh Tools > Healing Wizard to remove abnormal faces. Click OK with default options.

4. Click Tools > Mesh Tools > Global Remesh to retriangulate the faces and improve the quality of faces. Uncheck Make Clean And Manifold Solid Mesh option in the dialog tree. Click OK. You can get very regular size of triangles.

<Before Global Remesh> <After Global Remesh>

Note

If Make Clean And Manifold Solid Mesh option is enabled, a clean closed mesh is created. Use this option only in closed mesh. As the current model is open mesh, this option is disabled.

5. Click Tools > Mesh Tools > Decimate to reduce the number of faces by merging vertices. Select the reduction ratio as 25%.

6. You can use to identify and navigate to the holes.

7. Click Tools > Mesh Tools > Fill Holes to fill the holes in the model. Click (Don’t Close Controls) button and select the hole and click OK.

Click button to fill the holes at the boundary, as shown below. Select an edge and drag it to opposite edge like creating a bridge. Click OK.

Fill hole which is created by bridge.

8. Click Tools > Mesh Tools > Enhance to remove the noise.

9. Click Tools > Mesh Tools > Edit Boundaries to edit the boundaries to the correct shape. Select the Method as Fit and Fitting Shape as Auto and select the following boundaries.

10. For the outer boundary, select the Method as Fit and Fitting Shape as FreeForm.

11. Click Tools > Mesh Tools > Optimize Mesh to optimize the mesh data. The final image looks as shown below.
