Function Syntax: NamespaceFix Version: 1.1 Date: 20.06.2026 4:47:54PM N/A Description 🛠️ 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. Function Syntax 🚀 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. SEO Optimized Overview 🛠️ 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. 🔄 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. Core AutoCAD / Civil 3D Workflow ✅ 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. Important Functions and Implementation Details 🧩 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. Result 🎯 AutoLISP multiplication expressions continue working after SAVE/QSAVE. 🧩 Tools depending on the built-in * operator are protected against namespace pollution. 🛠️ The CAD environment receives a defensive self-healing startup routine. Important Notes ⚠️ This is a defensive repair tool, not a replacement for fixing the original routine that overwrites *. ⚠️ It should be loaded intentionally from a trusted startup path because it installs a persistent command reactor for the session. ℹ️ The code is designed for AutoCAD/Civil 3D Visual LISP environments.
