Description

Creates a model type constraint based on the length of a list of nodes.

Inputs

stype: SHAPES
smark: Mark number of shapes
type: 0 - Measure length node to node; 1 - Measure length using vector
name: Name of morph constraint
nodes: Mark number of node list
vec: The ID of the vector created using *createvector. Must be set to 1.
length: Constrained length of node list
bound: -1 - Greater than specified length; 0 - Equal to specified length; 1 - Less than specified length
color: The color of the constraint. Valid values are 1 through 64.

Example

*morphconstraintcreatelength (SHAPES,1,0,"length",1,1,43.5,0,32)

This command creates a model type constraint for the selected node list with the option of having those nodes measured node to node or along a vector and the option of having the node list forced to be greater than, less than, or equal to the specified length.

The shapes on the mark will be used to force the model into compliance with the specified constraint, if possible.

Errors

None.
