Function Syntax: MleaderStraightTools Version: 1 Date: 29.09.2025 AI+https://forums.autodesk.com/t5/visual-lisp-autolisp-and-general/changing-mleader-aligner-function-to-apply-to-all-mleaders-in/m-p/9062067#M83632 Description This program allows you to automatically straighten MLeaders in AutoCAD so that their leader lines become perpendicular (horizontal or vertical) to the arrow base. The user is given a small dialog box (DCL) to choose how to process the MLeaders. Functionalities • Option 1: Select MLeaders interactively – You can pick objects manually, use windows or crossing windows. – Supports Ctrl to add more and Ctrl+Shift to unselect. – Also supports preselection (objects selected before running the command). • Option 2: Process all MLeaders in the current space – Works in Model space or the active Paper space layout. – Automatically collects all MLeaders from the active tab. • After processing, leader lines are adjusted to be straight (either vertical or horizontal), depending on their relative positions. • Temporary construction lines (XLINE) are created and deleted during processing to calculate exact perpendicular points. • The drawing is regenerated (REGEN) after modification. Command Name Run the command by typing: MleaderStraight Notes • Works seamlessly in both Model and Paper space. • Best experience when PICKFIRST=1 and PICKADD=2.
