*untrim_selected_edges
Untrims selected surface free edges.
Syntax
*untrim_selected_edges mark_id_lines mark_id_surfs untrim_option keep_vertices reserved1 reserved2
Type
HyperMesh Tcl Modify Command
Description
- In case of "shortcut" option, the new straight edge joins the end-points of selected edge chain.
- In case of "extend" option, the command attempts to finds the intersection of two rays along tangents at the edge chain end-points. If such an intersection point exists, the new straight edges join the end-points of original edge chains with this intersection point.
The input can include free edges on several surfaces simultaneously, and can include both internal and external free edges. The command ignores all non-free edges of the selection.
If all edges of an internal or external loop are selected, the command would remove the entire loop. In these special cases, the command extends the functionalities of *edgesmarkuntrim and *surfacemarkuntrim.
Inputs
- mark_id_lines
- The ID of the mark containing the free edges to untrim. Valid values are 1 and 2.
- mark_id_surfs
- Reserved for future use.
- untrim_option
- Specifies how the new edges be constructed:
- keep_vertices
- 0 - Vertices at the ends of the selected edge chains might be removed if necessary (based on the value of the user-specified "geom. feature angle")
- reserved1
- Reserved for future use. Must be set to 0.
- reserved2
- Reserved for future use. Must be set to 0.
Example
To untrim the red edges with ID 36800-36802 via shortcut option and to preserve the vertices at the ends of the selected edge chains:
*createmark lines 2 36800 36801 36802
*createmark surfaces 2
*untrim_selected_edges 2 2 0 1 0 0
