*findandremovethreads
Finds cylindrical threads in 3D geometry and replaces them with smooth surfaces.
Syntax
*findandremovethreads entity_type mark_id max_depth replacement_type flags reserved1 reserved2
Type
HyperMesh Tcl Modify Command
Description
This command tries to recognize threads with a depth less than the specified maximum value. Then the recognized threads are replaced with simple smooth surfaces (usually a combination of cylinders, cones and smooth NURBS surfaces). A search for recognition and removal of threads is performed within a given selection of surfaces or solids. Optionally, the input selection can be considered as a seed selection, allowing attached surfaces to also become involved in the recognition and removal.
Inputs
- entity_type
- The entity types to find threads in. Valid values are surfs and solids.
- mark_id
- The mark ID containing the entities. Valid values are 1 and 2.
- max_depth
- The maximum depth of threads to find and remove.
- replacement_type
- The type of major cylinder surface to use for replacing the thread:
- -2 - Autodecide (by minor diameter for holes, by major diameter for bolts).
- -1 - Replacement by minor diameter.
- 0 - Replacement by mean diameter.
- 1 - Replacement by major diameter.
- flags
- Flags controlling the mode of thread removal. Bit values are used and the value is
calculated as (Bit0).
- Bit0
- 0 - Attached surfaces can also be considered, with input surfaces used as seeds.
- reserved1
- Reserved for future use. Must be set to 0.
- reserved2
- Reserved for future use. Must be set to 0.
