- If the dictionary is named 'surfaces', a 'surfaces' entry is mandatory.
This is a list of wordRe, which is used to load multiple surfaces from
constant/triSurface directory.
- Other dictionaries may contain a 'surfaces' entry.
In which case the behaviour is as above (loading multiple surfaces).
The dictionary name will *NOT* be taken as a surface name itself.
- Regardless of how the surfaces are loaded or features extracted,
an additional selfIntersection test may be used.
Eg,
surfaces
{
extractionMethod extractFromSurface;
surfaces (surface1.stl surface2.nas);
// Generate features from self-intersect
selfIntersection true;
// Base output name (optiona)
output surfaces;
// Tolerance for self-intersect
planarTolerance 1e-3;
extractFromSurfaceCoeffs
{
includedAngle 120;
// Do not mark region edges
geometricTestOnly yes;
}
