B-Rep simplification tool which removes holes from the model.
This tool traverses the scene graph and re-creates the model skipping the faces that were recognized as lying inside holes. Then it sews resulting holes so the result is a collection of closed shells.
The tool is parameterized by different thresholds which determine what to do with holes with some small part outside of hole. We calculate approximating bounding box of outside part and check thresholds to see if it can be dismissed.

Constructor.
| LicenseManager_LicenseError | if no Model Simplifier license was activated. |
| double cadex::ModelSimplifier_HoleRemoverTool::DiagonalThreshold | ( | ) | const |
Returns the diagonal threshold of body size, below which the body is considered small.
Size is measured as the length of the diagonal of an object's axis-aligned bounding box. The threshold is relative to the part's size (i.e. the value of 0.1 means all bodies smaller than 10% of the part's size should be removed), therefore the meaningful range of this parameter is [0, 1].
Default value is 0.05, i.e. 5% of part's size.
| double cadex::ModelSimplifier_HoleRemoverTool::ExtentThreshold | ( | ) | const |
Returns the extent threshold of body size, below which the body is considered small.
Size is measured as the extents of an object's axis-aligned bounding box. The threshold is relative to the part's AABB (i.e. the value of 0.1 means all bodies with at least one extent less then than 10% of the part's AABB extent should be removed), therefore the meaningful range of this parameter is [0, 1].
Default value is 0.02, i.e. 2% of part's size.

Runs the hole removal algorithm and returns the model without holes.
The original model is not modified.
The method can be invoked multiple times with different models.
Implements cadex::ModelSimplifier_SimplifierTool.
| bool cadex::ModelSimplifier_HoleRemoverTool::PerformInterferenceCheck | ( | ) | const |
Returns the flag of performing interference check.
This check ensures that resulting bodies will not be self interesecting after holes were removed.
Default value is true.
| double cadex::ModelSimplifier_HoleRemoverTool::VolumeThreshold | ( | ) | const |
Returns the volume threshold of body size, below which the body is considered small.
Size is measured as the volume of an object's axis-aligned bounding box. The threshold is relative to the part's volume (i.e. the value of 0.1 means all bodies with volume less then than 10% of the part's volume should be removed), therefore the meaningful range of this parameter is [0, 1].
Default value is 0.005, i.e. 0.5% of part's size.
