*featurelinesdetection
Performs feature line detection using the curvature-based method.
Syntax
*featurelinesdetection entity_type mark_id edge_feature_angle min_curvature max_curvature
Type
HyperMesh Tcl Modify Command
Description
Performs feature line detection using the curvature-based method. This method analyzes surface curvature and edge angles to generate topology lines from a mesh.
Inputs
- entity_type
- The input entity type. Valid values are elements and components.
- mark_id
- The ID of the mark containing the input entities.
- edge_feature_angle
- The edge feature angle. Valid value range is 1-180. If set to 180, angle-based feature detection is disabled.
- min_curvature
- The minimum curvature filter.
- max_curvature
- The maximum curvature filter.
Examples
To generate features on displayed elements using edge feature angle of 30.0
degrees:
*createmark elems 1 displayed
*featurelinesdetection elems 1 30.0 0 0Errors
Incorrect usage results in a Tcl error. To detect
errors, you can use the catch
command:
if { [ catch {command_name...} ] } {
# Handle error
