Description

Performs equivalencing of edges within surfaces or/and between surfaces.

Inputs

mark_id: The ID of the mark containing the surfaces. Valid values are 1 and 2.
allow_self_stitch=<value>: Specifies whether to consider stitching edges of the same surface. Valid values are:; 0 – Do not consider self-stitching. 1 – Consider self-stitching (same surface edges). (default)
allow_stitch_different_surfs=<value>: Specifies whether to consider stitching edges between different surfaces. Valid values are:; 0 – Do not stitch edges between different surfaces.; 1 – Stitch edges between different surfaces. (default)
stitch_only_free_edges=<value>: Specifies whether to restrict to free edges for stitching. Valid values are:; 0 – Consider all edges.; 1 – Consider free edges only. (default)
allow_small_edge_collapse=<value>: Specifies whether to allow collapsing small edges when stitching. Valid values are:; 0 – Do not collapse small edges. (default); 1 – Collapse small edges.
equivalence_to=<value>: Specifies which edges to consider for stitching. Valid values are:; across_comp – Allow equivalence between components. (default); within_comp_only – Do not equivalence between components.; to_connected_surfs - Equivalence between selected surfaces and surfaces connected to selection.; within_selection – Equivalence only within the subset of selected surfaces.
tolerance_across=<value>: The equivalencing tolerance value for edges of different surfaces. The default geometry tolerance is used if this input is not specified.
tolerance_within=<value>: The equivalencing tolerance for edges within a single surface. The default geometry tolerance is used if this input is not specified.

Example

To equivalence edges between all displayed surfaces using a tolerance value of 0.2:

*createmark surfs 1 displayed
*selfstitchcombine2 mark=1 tolerance_across=0.2 tolerance_within=0.2

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
