NamespaceFix

Short description

πŸ› οΈ NamespaceFix is an AutoCAD/Civil 3D AutoLISP repair utility that restores the built-in multiplication operator * when another LISP routine overwrites it.
πŸ”„ It installs a command reactor so the repair is checked automatically after SAVE or QSAVE workflows.

Command:

πŸš€ Load/install file: NamespaceFix.lsp
🧰 Startup Suite use: add the LSP to APPLOAD Startup Suite for automatic protection.
🧩 Internal repair functions: C3D-RestoreStar and C3D-RestoreStarCmd
πŸ”„ Reactor: vlr-command-reactor with :vlr-commandEnded callback.

Description:

πŸ› οΈ NamespaceFix is an SEO-friendly AutoCAD AutoLISP namespace repair tool for drawings or startup environments where another script corrupts the global * symbol.
⚠️ The source comments identify the root cause as a separate pltools-eng6.lsp routine using (setq * …) as a variable name, which overwrites AutoLISP’s built-in multiplication operator.
πŸ”„ The utility installs a command-ended reactor and repairs * after command completion, especially after SAVE/QSAVE workflows where the conflicting routine is loaded by a save reactor.
🧠 The repair attempts to rebuild Visual LISP built-ins with vl-load-com, then falls back to the internal acad_* function pointer when available.
πŸ“Œ This is useful for Civil 3D startup suites, production CAD environments, debugging broken AutoLISP expressions, and stabilizing tools that depend on normal arithmetic behavior.

Helper function: (if any)​

🧩 C3D-RestoreStar checks whether (type (eval ‘*)) is still SUBR.
🧩 C3D-RestoreStarCmd is the command-reactor callback wrapper.
🧩 vl-load-com is used as the first repair attempt to rebuild the Visual LISP environment.
🧩 acad_* is used as a fallback source for the multiplication SUBR when the * symbol is already corrupted.
🧩 vlr-command-reactor installs the automatic repair hook for command-ended events.

Functionalities:

βœ… Detect broken AutoLISP multiplication operator symbol.
βœ… Repair * automatically after save-related command activity.
βœ… Repair immediately on load if the symbol is already damaged.
βœ… Print command-line status messages such as * OK on load or * repaired on load.
βœ… Avoid editing the conflicting third-party/source LISP directly.

Result:

🎯 AutoLISP multiplication expressions continue working after SAVE/QSAVE.
🧩 Tools depending on the built-in * operator are protected against namespace pollution.
πŸ› οΈ The CAD environment receives a defensive self-healing startup routine.
