- When using the "By Location" option, a separat e dialog box appears for defining path points (PPATH
command). Enter the Global Cartesian coordinate values of the path points. The shape of the inter-
polated path geometry will follow the currently active CSYS coordinate system. Alternatively, you can
specify a coordinate system for geometry interpolation (CS argument on the PPATH command).
NoteTo see the status of path settings, choose the PATH,STATUS command.The PATH and PPATH commands define the path geometry in the active CSYS coordinate system. If the
path is a straight line or a circular arc, you need only the two end nodes (unless you want highly accurate
interpolation, which may require more path points or divisions).
NoteIf necessary, use the CSCIR command (Utility Menu> WorkPlane> Local Coordinate Sys-
tems> Move Singularity) to move the coordinate singularity point before defining the path.To display the path you have defined, you must first interpolate data along the path (see Interpolating
Data Along the Path (p. 172)). You then issue the /PBC,PATH,1 command followed by the NPLOT or
EPLOT command. Alternatively, if you are using the GUI, choose Main Menu> General Postproc> Path
Operations> Plot Paths to display the path on a node plot or choose Utility Menu> Plot> Elements
followed by Main Menu> General Postproc> Path Operations> Plot Paths to display the path on an
element plot.The program displays the path as a series of straight line segments. The path shown below
was defined in a cylindrical coordinate system:

7.2.5.2. Using Multiple Paths
A maximum of 100 paths can exist within one model. However, only one path at a time can be the
current path. To change the current path, choose the PATH,NAME command. Do not specify any other
arguments on the PATH command. The named path will become the new current path.
