This AutoLISP routine toggles the AutoCAD Navigation Cube (ViewCube) display by sending direct commands through the Active Document COM interface. It ensures that the cube display setting is refreshed properly by first turning it off and then immediately turning it back on.

This AutoLISP package provides a full workflow for exporting and importing named UCS definitions using dialogs, predefined OneDrive folders, clipboard helpers, and a help window that stays open. It is designed to work in an environment where UCS files are stored in shared/network/OneDrive folders and where users need to switch between ExpUCS, ImpUCS and a combined ExpImpUCS dialog. It also includes an enhanced COM-only UCS importer at the end, so importing UCS does not freeze or prompt, and it can overwrite/update UCS definitions silently.

This AutoLISP routine lets the user rotate the current UCS around the Z axis by a user-specified angle, resets the snap angle, and optionally saves the new UCS under a custom name. It is useful when drafting in rotated views but still wanting a clean UCS orientation for further drawing.

This AutoLISP routine is made for AutoCAD Civil 3D and is used to quickly set the drawing’s coordinate system, drawing scale, angular units and linear drawing units from one dialog. It reads the Civil 3D COM objects and applies the settings directly to the active document, so the drawing is ready for civil work after one configuration step.
