NamespaceFix

Short description

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

Command:

🚀 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
🔄 Reactor: vlr-command-reactor with :vlr-commandEnded callback.

Description:

đŸ› ī¸ NamespaceFix is an SEO-friendly AutoCAD AutoLISP namespace repair tool for drawings or startup environments where another script corrupts the global * symbol.
âš ī¸ 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.
🔄 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.
📌 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:

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

Result:

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