PCL for Everyone

?

Session files can be executed or “played” by selecting File/Session/Play … from the top menu.

If “Single Step” is selected, each command in the session file is written to the MSC.Patran command line. You must hit the enter key to execute the command. If it is not selected, then all of the PCL commands in the session file are executed automatically. If “Commit Commands” is selected, then each command in the session file being executed is also written to the session file which is currently being recorded. Otherwise, only the sf_play(…) command is written to the session file being recorded.

The variable “radius” declared as a REAL number The variable “radius” is initialized to 1

Upon application, the PCL interpreter evaluates `radius` (i.e., sets it equal to 1.0 in this example) and creates the curve. Note that the variable is passed to the session file in its unevaluated form.

By using variables as parameters during MSC.Patran input, it is very easy to edit and change dimensions, mesh parameters, etc. in the session file.
