*scalemarkwithsystem
Scales a selection of entities by multiplying the coordinates relative to the specified system.

Description
This command scales a selection of entities by multiplying the coordinates.
Inputs
- entity_type
- The type of entity to translate.
- mark_id
- The ID of the mark containing the entities. Valid values are 1 and 2.
- scale_x
- The multiplication factor for the x-axis of the system.
- scale_y
- The multiplication factor for the y-axis of the system. Only used in rectangular coordinate systems.
- scale_z
- The multiplication factor for the z-axis of the system. Not used in spherical coordinate systems.
- system_id
- The ID of the system which the scaling is in relation to. Note that the type of system affects the scaling. For example, specifying scale_x in a cylindrical or spherical coordinate system scales the mark radially out from the origin.
- origin
- If zero, the scaling is based at the origin of the system. Otherwise, it specifies a node ID whose coordinates define the base point of the scaling.
Example
To scale nodes 1-8 5 units in the x-direction of system 13 with node 20 as the origin:
*createmark nodes 1 1-8
*scalemarkwithsystem nodes 1 5.0 1.0 1.0 13 20
To scale the rigid wall rwcyl relative to the rigid wall local system:
*createmark groups 1 rwcyl
*scalemarkwithsystem groups 1 3.0 1.0 1.0 0 0
