Lower

Home > Autocad Lisps > Text_menu > Lower

Short description

Sort / Purpose: Convert selected TEXT and MTEXT entities to either all upper case or all lower case in a single operation. • Scope: Operates only on existing TEXT and MTEXT objects that you select in the drawing. • Goal: Standardize the letter case of annotations quickly for consistent drawing documentation.

Command:

Command name: CASE How to run: Type CASE in the command line and press Enter.

Description:

• Selection: Prompts the user to select TEXT and MTEXT entities to be modified. • Case Option: Lets the user choose between converting to Upper or Lower case, with Upper as the default when Enter is pressed. • Processing: Reads each entity’s text content, converts it, and writes the new value back to the entity. • System Handling: Temporarily disables command echo and precision settings, restoring them afterward. • Failure Handling: Warns the user if no valid text entities are detected in the selection.

Helper function: (if any)

Used AutoLISP / AutoCAD built-ins: • getvar / setvar: Save and restore CMDECHO and LUPREC values. • ssget / ssname / sslength: Build and iterate through the selection set of text entities. • entget / entmod: Read and rewrite DXF data of each text entity. • assoc / subst: Extract and replace group code 1 (text string). • strcase: Convert existing text to upper or lower case. • initget / getkword: Provide and enforce the “Upper/Lower” option selection. • prompt / princ: Display clean messages and terminate silently.

Functionalities:

• Supports TEXT & MTEXT: Works on both object types simultaneously. • Uppercase Mode: Converts all selected text content to uppercase. • Lowercase Mode: Converts all selected text content to lowercase. • Default Behavior: Uppercase is automatically used if no choice is provided. • Non-Destructive: Only the string content is modified; all other entity properties remain unchanged. • Environment-Safe: Resets all system variables changed during execution.

Result:

Result: All selected TEXT and MTEXT entities are converted to the chosen case (Upper or Lower) instantly. • Uniform Formatting: Every selected annotation ends with consistent capitalization across the drawing. • Non-destructive: Only the text content changes — layer, style, color, rotation, and position remain untouched. • Clean Execution: System settings are restored automatically, leaving the environment unchanged after the command finishes. • Immediate Feedback: The text updates visually in the drawing as soon as the command loops through all entities.

<Bold>Functionalities</Bold><LineBreak/>
• Select multiple <Span Foreground="DarkRed">TEXT</Span> and <Span Foreground="DarkRed">MTEXT</Span> objects for case conversion.<LineBreak/>
• Option to convert all text to <Span Foreground="DarkRed">Upper</Span> or <Span Foreground="DarkRed">Lower</Span> case.<LineBreak/>
• Uses <Span Foreground="DarkRed">strcase</Span> function with optional lowercase flag.<LineBreak/>
