hm_xformnodetolocal

Returns the coordinates of a node relative to a local coordinate system.

Syntax

hm_xformnodetolocal node_id syst_id

Type

HyperWorks Tcl Query Command

Description

This command returns the coordinates of node_id relative to the coordinate system syst_id.

This is useful for finding distances relative to local coordinate systems.

Inputs

node_id
The coordinates of node_id relative to the coordinate system syst_id are returned.
syst_id
If syst_id is a rectangular system, x, y, and z are returned. If syst_id is a cylindrical system, r, t, and z are returned. If syst_id is a spherical system, r, t, and p are returned. syst_id of 0 returns the global x, y, and z coordinates.

Example

To get the coordinates of node ID 50 relative to system ID 5:

hm_xformnodetolocal 50 5

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:
if { [ catch {command_name...} ] } {
   # Handle error
}
If node_id does not exist, you will get the following error:
Node node_id could not be found.
If syst_id does not exist, you will get the following error:
System syst_id could not be found.
