Description

This command will scale the positions of the selected handles with respect to a reference node and system. Scaling factors can be assigned for the x, y, and z directions independently. If no system is specified, the scaling factors will apply in the global x, y, and z directions. If no node is specified, the handle positions will be averaged to determine the position of the reference node. A scaling factor of 1.0 will produce no movement of the handle in that direction while a scaling factor of 0.0 will move the handle to the x, y, or z position of the node or system origin.

Inputs

h_entity_type

Must be set to handles.

h_mark_id

The mark ID of the handles. Valid values are 1 and 2.

node_id

ID of the scaling reference node (or 0).

x

Scaling factor in the x direction (1.0 is no scaling).

y

Scaling factor in the y direction (1.0 is no scaling).

z

Scaling factor in the z direction (1.0 is no scaling).

system_id

ID of the scaling reference system (or 0).

sym

0 – Do not use symmetry links between handles

1 – Use symmetry links between handles

con

0 – Do not apply constraints

1 – Apply constraints

Examples

To scale a mark of handles relative to a node and system:

*createmark handles 1 "all"
*morphscalehandlexyz handles 1 5 2.0 2.0 2.0 2 1 1

To scale a mark of handles relative to the average position of the handles using the global system for x, y, and z:

*createmark handles 1 "all"
*morphscalehandlexyz handles 1 0 2.0 2.0 2.0 0 1 1

Errors

if { [ catch {command_name...} ] } {
