Defeaturing the Geometry
1
In the Geometry toolbar click Defeaturing and Repair and choose Delete Sliver Faces .
2
In the Maximum face width text field enter 5[mm].
3
Click Find Sliver Faces.
The 18 sliver faces that are detected are displayed in the Sliver face selection list.
4
Select for example Sliver face 8 from the list, then click Zoom Selected next to the list to find the face in the Graphics window.
A sliver face is a face with a high aspect ratio. If it is not removed from the geometry it may cause problems during meshing. Remaining sliver faces in the list are located on the bezel of the flat screen TV, and some other on the two couches.
5
To remove the sliver faces click the Delete All button below the list.
Continue with deleting some larger faces to further simplify the geometry, and also to create new faces on the front of the bookshelf.
6
From the toolbar in the Settings window for Delete Sliver Faces click the Delete Faces button.
7
Check that Activate Selection is selected next to the Faces to delete list before continuing to the next step.
The Delete Faces tool can delete faces from an object, and cover the resulting wound by growing (or shrinking) adjacent faces.
8
First, select, on both couches, the faces that are highlighted in the figure below. There are 5 faces located on the back and bottom of each couch.
9
Continue with selecting the highlighted faces on the sides of each armrest on the couches. There are 4 faces on each couch.
10
Finally select the highlighted faces on both sides of the bookshelf. There are 5 faces for each shelf.
11
Click Delete Selected.
The last step before meshing is to find and delete spikes that still remain in the geometry. Similarly to a sliver face, a spike is a region in a face that has a high aspect ratio.
12
From the toolbar in the Settings window for Delete Faces click the Delete Spikes button.
13
In the Maximum spike width text field enter 10[mm].
14
Click the Find Spikes button.
15
The tool detected 4 spikes. Select Spike 4 and click Zoom Selected to zoom in on the edges that comprise the spike.
16
Click Delete All to remove all spikes.

To restore the default view click Go to Default 3D View in the Graphics toolbar.
