Distance Threshold: specifies the distance value between 0.001mm
and 0.1 mm below which the elements are extracted.
Important:
The default value is 0.1mm, except if a Merging
Distance has been defined different from 0.001mm in Me > Preferences > App Preferences > 3D Modeling > 3D Modeling Core> Generative Shape Design, Generaltab.
In this case, the Distance Threshold value is initialized
with the Merging Distance value.
This option is available with all propagation types, except for the No
propagation type.
Angular Threshold: specify the angle value between 0.5 degrees
and 5 degrees below which the elements are extracted (the default value is 0.5deg).
Curvature Threshold: specifies a ratio between 0 and 1 which is
defined as follows:
if ||Rho1-Rho2|| / max (||Rho2||,||Rho1||) < (1-r)/r where Rho1
is the curvature vector on one side of the discontinuity, Rho2 the curvature vector on
the other side, and r the ratio specified by the user; then the discontinuity is
smoothed.
For instance, r=1 corresponds to a continuous curvature and r=0.98 to the model
tolerance (default value). A great discontinuity requires a low 'r' to be
considered.
Curvature Threshold = 0.98
Curvature Threshold = 0.80
Curvature Threshold = 0.50
Tips:
When Point continuity is selected, only the
Distance Threshold is activated
When Tangent continuity is selected, both
Distance and Angular Thresholds are
activated
When Curvature continuity is selected,
Distance, Angular, andCurvature Thresholds are activated.
Recognition context
You can select a recognition context for the Depression/Protrusion propagation types.
The industries proposed have specific ranges which are subject to change,
in particular Ship Building's one:
Definition of
Feature's industry's fillets radii range
Definition of
Feature's industry's chamfers lengths range
> Preferences > App Preferences > 3D Modeling > 3D Modeling Core
> Generative Shape Design, General
tab.
In this case, the Distance Threshold value is initialized
with the Merging Distance value.
