Contents

Action

Sets blending behavior with respect to engulfed features that lie completely inside the region replaced by a blend.

Name String

bl_retain_features

Scheme

Type Values Default
boolean #f, #t #f

C++

Type Values Default
logical FALSE, TRUE FALSE

Description

When this option is enabled, bl_retain_features determines how to handle features that lie completely inside the region replaced by the blending operation. When this option is disabled (set to FALSE) and when the blend completely engulfs any feature, the entire feature is lost. By enabling this option (setting this option to TRUE), ACIS Blending detects those features and attempts to retain all features that are engulfed.

Note: This option is effective in edge blending only, that is, in the following APIs:

api_blend_edges api_chamfer_edges
api_blend_edges_pos_rad api_set_const_chamfers
api_blend_holdline api_set_const_rounds
api_abh_chamfer_edges api_set_var_blends

Note: This option does not have any effect on features that are partially inside and partially outside the blend region.
