Function Syntax: NavvCubeDisplayOffOn Version: 1.1 Date: 20.06.2026 6:38:51PM AI+https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/View-cube-and-navitation-bar-disappeard.html Function Syntax: NavvCubeDisplayOffOn Command: NavvCubeDisplayOffOn Description 🧭 NavvCubeDisplayOffOn is a compact AutoCAD AutoLISP utility for resetting the Navigation Cube display state with one command. It helps AutoCAD and Civil 3D users quickly restore the navigation cube or NavVCube display without searching through workspace, view, or interface settings. Main Command 🚀 Run NavvCubeDisplayOffOn in the AutoCAD command line to execute the display reset. 🧰 The routine sends the AutoCAD command NAVVCUBEDISPLAY directly to the active document. 🔄 Internal sequence used by the uploaded code: NAVVCUBEDISPLAY 1 followed by NAVVCUBEDISPLAY 3. SEO Optimized Description 📘 This AutoCAD Navigation Cube utility provides a fast command-line workflow for refreshing the NavVCube display in the current drawing session. 🖥️ It is useful when the navigation cube visibility needs to be restored after workspace changes, screen layout changes, Civil 3D production work, or display cleanup. 📌 The command is lightweight and focuses only on the AutoCAD interface display setting. It does not select, edit, erase, or create drawing geometry. Functionalities 🚀 One-command display reset - runs NavvCubeDisplayOffOn to refresh the navigation cube display state. 🧭 Navigation cube control - uses NAVVCUBEDISPLAY to control the AutoCAD NavVCube display workflow. 🔄 Two-step command sequence - sends value 1 and then value 3 to force a display-state refresh. 🧰 Active document automation - gets the current drawing through vla-get-ActiveDocument and runs commands using vla-sendcommand. ⚡ No object selection required - the command does not ask the user to select drawing entities. 🔒 Non-geometric operation - model-space objects, layers, blocks, xrefs, and Civil 3D data are not modified. Technical Notes 🧩 The routine uses vlax-get-acad-object to connect to AutoCAD and vla-sendcommand to issue the display commands. 🔧 It includes a vl-catch-all-apply check around the AutoCAD COM object call and loads Visual LISP COM support when required. 📌 The uploaded source is intentionally minimal and does not include a DCL dialog, saved settings, preview panel, or report export. Practical Result ✅ The final result is a quick AutoCAD and Civil 3D interface utility that refreshes the navigation cube display from the command line. This improves CAD workspace usability, screen navigation, drafting comfort, and production speed when the Navigation Cube display needs to be restored quickly. Important Note ⚠️ This routine changes only an AutoCAD display or interface setting through NAVVCUBEDISPLAY. It does not modify drawing content.
