Function Syntax: EXPUCS_DIALOG / IMPUCS_DIALOG / EXPUCS / IMPUCS Version: 1.1 Date: 20.06.2026 6:38:51PM AI+https://forums.augi.com/showthread.php?94673-Is-any-method-to-export-ucs Description 🧭 Export_Import_MS_UCS is an AutoCAD AutoLISP utility for exporting and importing named UCS definitions through portable .ucs files. It helps CAD users transfer model-space UCS setups between drawings, preserve project coordinate systems, and reuse named UCS standards in AutoCAD and Civil 3D production workflows. Function Syntax 🚀 Export dialog command: EXPUCS_DIALOG 🚀 Import dialog command: IMPUCS_DIALOG 📤 Raw export routine: EXPUCS 📥 Raw import routine: IMPUCS Export UCS Workflow 📤 The export command opens a save-file dialog allowing the user to write named UCS data from the current drawing to a reusable .ucs file. 📐 The exported file stores UCS table records so project-specific coordinate systems can be transferred to another DWG without rebuilding the origin and axis setup manually. 💾 The last-used folder is saved in the Windows Registry, making repeated UCS exports faster in project folders. Import UCS Workflow 📥 The import command opens a file-selection dialog allowing the user to select a previously exported .ucs file. 🧭 The routine reads UCS records from the file and recreates them in the active drawing using AutoLISP table and entity creation logic. 🔁 If an imported UCS name already exists, the routine generates a unique name by appending underscores, avoiding direct overwrite of existing UCS definitions. Functionalities ✅ Collects named UCS records from the current AutoCAD drawing. ✅ Exports named UCS definitions to a portable .ucs file. ✅ Imports named UCS definitions from a saved .ucs file. ✅ Uses AutoCAD file dialogs through getfiled for export and import path selection. ✅ Remembers the last-used UCS folder across sessions using the Windows Registry. ✅ Defaults to the current drawing folder when no previous UCS folder has been saved. ✅ Uses tblnext, tblsearch, entmake, open, read-line, and write-line for UCS file processing. ✅ Supports Civil 3D and AutoCAD production workflows where UCS consistency is important across model-space drawings, layouts, xrefs, and project files. Highlights 🧠 The tool reduces repetitive UCS setup work by turning named coordinate systems into reusable file-based data. 🗂️ The Registry path HKEY_CURRENT_USER\Software\JTBWorld\ucsdialog stores the last export or import folder. 📌 The workflow is practical for UCS_Lageplan management, xref coordination, plan production, model-space orientation transfer, and CAD standardization. Practical Result 🎯 The final result is a portable named UCS workflow for exporting, archiving, sharing, importing, and reusing AutoCAD User Coordinate Systems between drawings. This improves project setup consistency, reduces manual UCS recreation, and supports cleaner CAD production standards. Important Notes ⚠️ The uploaded LSP writes and reads raw UCS table records in a .ucs text file. ⚠️ It is intended for named UCS definitions and does not export geometry. ⚠️ Review imported UCS names when the target drawing already contains similarly named UCS records.
