Unlocking Automation: A Deep Dive into Creo Mapkeys and OS Scripting Examples

In the world of parametric CAD, time is the ultimate currency. For engineers and designers using PTC Creo Parametric, repetitive tasks—such as setting configurations, exporting neutral files, or running regenerations—can consume hundreds of hours annually. While Creo’s native Mapkeys (macro recorder) are powerful, their true potential is only unleashed when integrated with Operating System (OS) scripting (e.g., Windows Batch, PowerShell, or Python).

This article provides a comprehensive guide to bridging Creo Mapkeys with external OS scripts. You will learn not just how to record a Mapkey, but how to call external programs, pass variables, and build a fully automated design pipeline.

3. Asynchronous Mayhem

You cannot run OS_Script delete_temp_files.bat and immediately OS_Script erase current.prt in the same Mapkey. The first script might still be running when the second starts. Fix: Use !OS_Script (sequential) or merge your logic into a single master script.

Mapkey (assign to F12)

mapkey $F12 @MAPKEY_NAMERelease to MFG;\
~ Command `ProCmdModelSaveAs` ;\ 
~ Select `file_saveas` `type_option` 1 `STEP`;\
~ Open `file_saveas` `ph_list.Filelist`; \
~ Select `file_saveas` `ph_list.Filelist` 1 `C:\CREO_EXPORTS\current.step`;\
~ Command `ProCmdFileSave` ;\
~ Command `ProCmdPrint` ;\
~ Select `print_dlg` `pdf_export_btn` 1 ;\
~ Activate `print_dlg` `OK` ;\
~ Delay 1 ;\
~ Command `ProCmdUtilSystem` `system("C:\scripts\release_to_manufacturing.bat &model_name &pro_mp_revision")`;\
~ Command `ProCmdFileEraseNotDisp` ;

Note: &model_name and &pro_mp_revision are Creo system parameters. The Mapkey passes them as arguments to the batch file.

6. Security Considerations

Using @SYSTEM has security implications.

  1. Macro Viruses: A malicious mapkey could be embedded in a start-up config that runs format C: or deletes files. Never load config.pro files from untrusted sources.
  2. Permissions: Creo runs OS commands with the permissions of the user logged into Windows. If you cannot delete a file manually in Windows Explorer, a Creo Mapkey OS script cannot delete it either.
  3. IT Restrictions: Some IT departments disable the ability of applications to shell out to the OS.
