Short description
๐งญ ExpImpUCS is an AutoCAD and Civil 3D AutoLISP utility for exporting and importing named UCS definitions through a practical DCL dialog.
๐ค It helps CAD users save UCS setups to portable .ucs files, restore coordinate systems in another drawing, and reuse project-specific UCS_Lageplan folders with fewer manual steps.
Command:
๐ Main command: ExpImpUCS
๐ค Export command: ExpUCS
๐ฅ Import command: ImpUCS
๐งฐ The ExpImpUCS dialog lets the user choose Export UCS or Import UCS, select a predefined project folder, open the LISP folder in Explorer, open the file in Notepad++, reload the script, or open the integrated help dialog.
Description:
๐งญ ExpImpUCS is an SEO-friendly AutoCAD UCS import and export tool for managing named User Coordinate Systems in production drawings.
๐ค In export mode, the tool scans all named UCS definitions in the active drawing and writes them to a portable .ucs text file.
๐ฅ In import mode, the tool reads .ucs files line by line and creates or updates named UCS definitions in the active drawing.
๐๏ธ The exported UCS format stores the UCS name, origin point, X-axis point, and Y-axis point as Name;P1;P2;P3, making the file easy to reuse and inspect.
๐ง The latest importer uses COM-based UserCoordinateSystems logic to update UCS records directly, avoiding command-line UCS calls that can freeze or interrupt automated workflows.
๐ This is useful for Civil 3D layout drawings, coordinate control, Lageplan UCS setup, repeated project folders, Xref orientation workflows, and CAD production environments where UCS consistency is important.
Helper function: (if any)โ
๐งฉ EI-write-dcl dynamically creates the DCL interface for the main import and export dialog and the help dialog.
๐งฉ EI-build-predefs searches OneDrive and project paths for predefined UCS_Lageplan folders such as Beu, La, Npl, Bis, and Tp.
๐งฉ EI-preferred-startdir resolves the best start folder using the selected predefined folder, fixed LSP folder, last used folder, or DWGPREFIX.
๐งฉ EI-clipboard-put copies help text and folder paths using cmd | clip.
๐งฉ EI-help-dialog opens a persistent help window with copy selected, copy all, copy path, Unicode toggle, Explorer, and Notepad++ actions.
๐งฉ EI-open-explorer-fixed opens the fixed ExpImpUCS support folder.
๐งฉ EI-open-npp-fixed opens the fixed LISP file in Notepad++ when available, with Notepad fallback.
๐งฉ _ucs-add-or-update creates a new named UCS or updates an existing one through the AutoCAD UserCoordinateSystems collection.
๐งฉ _preferred-dir-from-dcl honors DCL-selected directories and then falls back through helper directory providers and the current drawing folder.
Functionalities:
โ
๐ค Export all named UCS definitions from the active drawing to a reusable .ucs text file.
โ
๐ฅ Import named UCS definitions from an external .ucs file and rebuild them in the active AutoCAD drawing.
โ
๐งญ Store UCS data as origin, X-axis point, and Y-axis point for reliable coordinate system reconstruction.
โ
๐ Update existing UCS definitions instead of blindly duplicating names.
โ
๐งฎ Normalize and validate UCS vectors before writing them to the UserCoordinateSystems collection.
โ
๐๏ธ Use predefined project folders for fast access to UCS_Lageplan directories.
โ
๐ Discover OneDrive project roots from environment variables, registry values, and user profile OneDrive folders.
โ
๐งฐ Use a DCL dialog for Export UCS, Import UCS, predefined folder selection, help, reload, Explorer, and Notepad++ actions.
โ
๐ Copy help text, selected help lines, and current path information to the clipboard.
โ
๐ค Toggle Unicode help output for better compatibility with older AutoCAD or Windows clipboard behavior.
โ
๐งน Skip empty, comment, malformed, or invalid UCS import lines safely.
โ
๐งฑ Keep the user workflow focused on UCS setup, coordinate transfer, CAD standardization, and drawing preparation.
Result:
๐ฏ The result is a faster and more controlled UCS management workflow for AutoCAD and Civil 3D.
๐ค Users can export named UCS definitions from one drawing, share the .ucs file, and import the same coordinate systems into another drawing.
๐ฅ The tool improves drawing setup consistency, reduces repetitive UCS recreation, and supports project-based folder structures used in infrastructure and Civil 3D production.
โ
ExpImpUCS is especially useful when multiple drawings must share the same custom UCS definitions for Lageplan work, xref coordination, layout checks, and repeated CAD standards.
