*morphhandleprojectlineoffset
Morphs a mesh by projecting selected handles on to the specified node list or line list.
Syntax
*morphhandleprojectlineoffset h_entity_type h_mark_id p_entity_type p_mark_id line_list node_list nproj proj sym con offset
Type
HyperMesh Tcl Modify Command
Description
This command moves each of the selected handles onto a line defined by the lines and nodes on the lists along a direction defined by the projection type. Applying symmetry links, constraints, and an offset are optional. All domains influenced by the selected handles will be morphed accordingly.
If nproj is set to 2, 5, or 6, the shell elements on p_mark_id will be used to determine the projection direction for the handles. If no elements are on the mark, then all shell elements will be used to determine the projection directions.
If symmetry is specified, handles linked through symmetry to those selected will be moved in a way that mirrors the selected handles which may or may not move them to other lines in the model.
Constraints may move the perturbed handles off the selected line after the handles are moved to the line.
The offset can be set as an absolute amount, an amount added to half the thickness of the shells touching the handles, or an amount multiplied by half the thickness of the shells touching the handles.
Inputs
- h_entity_type
- Must be set to handles.
- h_mark_id
- ID of the mark containing the handles. Valid values are 1 and 2.
- p_entity_type
- Must be set to elements.
- p_mark_id
- ID of the mark containing the normal elements. Valid values are 1 and 2.
- line_list
- ID of the line list for line. Valid values are 1 and 2.
- node_list
- ID of the node list for the line. Valid values are 1 and 2.
- nproj
- 0 - Project along vector proj
- proj
- ID of the temporary projection vector.
- sym
- 0 - Ignore symmetry links
- con
- 0 - Ignore constraints
- offset
- The distance the handles will be offset from line (or added to or multiplied by half the thickness of the shells touching the handles).
