Resting the cursor on a snap point acquires it for tracking (seven at most; resting again releases it). Acquired points send horizontal and vertical alignment paths, or every polar angle with POLARMODE 2; the cursor snaps where two paths cross, where a path crosses an object, or onto the nearest path. EXT runs a line or arc on from an acquired end, PAR gives a path parallel to a rested-on line through the base point, APP snaps where objects would meet if extended. Direct distance entry follows the path the cursor is on. POLARMODE is now AutoCAD's bitcode; POLARADDANG and AUTOSNAP are new. The engine owns all of it (Session::snap_cursor, snap/tracking.rs); the canvas draws the + markers, dotted paths and tooltip. Co-authored-by: Claude Opus 5.5 <[email protected]>
