Model.solid_cavity_detect_local

Model.solid_cavity_detect_local(collection, face_id, fill_flag)

Extracts cavity surfaces based on input rims and a face of that cavity.

This function must be followed by a call to Model.solid_cavity_detect_end().

Parameters:

• collection (Collection) – The collection containing the line entities of the surface edges defining the rims of the cavity.

• face_id (unsigned int) – The ID of a surface within the cavity.

• fill_flag (unsigned int) –

  0 - Creates a region entity.

  1 - Creates a solid from the cavity.

Example

Extract the cavity and creates a solid represent that cavity, with IDs of rim edges 1724 , 210 , 961 and 333 , and face ID 73
