*morphconstraintupdateline

Updates a line type morphconstraint for the selected nodes with the option of having those nodes either move along the line or be bounded by it.

Description

This command updates a line type morphconstraint for the selected nodes with the option of having those nodes either move along the line or be bounded by it.

Inputs

ntype: Must be set to nodes.
nmark: The ID of the mark for the constrained nodes. Valid values are 1 and 2.
type: 0 - moves along the line; 1 - bounded by the line; 3 - remains a set distance from the line; 5 - remains its original distance from the line; +32 - enable mesh stretching around constrained nodes. Add this value to the type (thus 1, 3, and 5 become 33, 35, and 37).
mcon: The ID of the morph constraint to update.
vec: The ID of the vector created using *createvector. Must be set to 1.
line: The ID of the line.
dist: The minimum distance from the bounding line.
ivec: 0 - The line normal is used for distance and projection. The nodes will be moved normally to the line when constraining them or measuring the distance the nodes are away from the line.; 1 - The vector is used for distance and projection. The nodes will be moved along the vector when constraining them or measuring the distance the nodes are away from the line.
color: The color of the constraint. Valid values are 1-64.

Example

To update a morphconstraint for nodes to move along a line and projected normally to the line:

*createmark nodes 1 1 2 3 4 5
*createvector 1 1.0 0.0 0.0
*morphconstraintupdateline nodes 1 0 12 1 12 0.0 0 32

Errors

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

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