LAYISO Isolate Layer is an AutoCAD AutoLISP script that streamlines drafting by quickly isolating selected layers in complex drawings. This AutoLISP routine provides a targeted command for AutoCAD users to isolate specific layers within a drawing file. By selecting a single object, the script automatically identifies its parent layer and suppresses the visibility of all other layers in the current workspace. This functionality is essential for decluttering dense technical drawings, such as architectural floor plans or intricate MEP layouts, allowing the designer to focus exclusively on relevant geometry. The script is lightweight, designed for seamless integration into standard CAD environments without requiring additional software dependencies or complex setup procedures.

The download is a single file containing .LSP files.

To implement this tool, load the LSP file into the current AutoCAD session using the APPLOAD command. Once active, the script is triggered via the defined command line alias. Users select a target object, and the routine immediately updates the layer state. It typically includes a companion command to restore the previous layer visibility settings, ensuring a non-destructive workflow when navigating between different drawing components or checking specific technical details during the design process.

This utility is highly effective for architects, interior designers, and engineers working on large-scale projects where layer management becomes cumbersome. It is particularly useful during the documentation phase for refining floor plans, electrical schematics, or structural details. By reducing the time spent manually toggling layer visibility in the Layer Properties Manager, the script improves overall productivity and accuracy. It serves as a fundamental productivity tool for any professional drafting environment, helping maintain clean, organised, and efficient CAD files throughout the project lifecycle.
