Short description
🚀 Converts selected AutoCAD polylines into leader geometry using the P2L command, copies the original polyline properties to the new leader, and removes the source polyline after conversion.
Command:
P2L
Description:
📘 ConvertPolylineAndText2Mleader is an AutoLISP drafting utility for AutoCAD users who need to convert selected POLYLINE or LWPOLYLINE geometry into leader-style annotation paths. The implemented command is P2L. It asks the user to select polyline objects, reads each vertex with Visual LISP curve functions, starts the AutoCAD LEADER command, places leader vertices from the original polyline path, applies MATCHPROP from the original polyline to the newly created leader, and deletes the original polyline. This makes it useful for drawing cleanup, annotation conversion, polyline-to-leader drafting workflows, and CAD production tasks where existing linework needs to become leader annotation geometry.
Helper function: (if any)
Functionalities:
[‘🚀 Runs from the AutoCAD command line with P2L.’, ‘📐 Selects supported polyline objects using ssget with the *POLYLINE filter.’, ‘🔄 Converts each selected polyline path into an AutoCAD LEADER sequence.’, ‘🧩 Reads polyline vertices using vlax-curve-getEndParam and vlax-curve-getPointAtParam.’, ‘🟢 Handles closed polylines by avoiding the duplicated closing vertex during leader creation.’, ‘🎨 Applies MATCHPROP so the generated leader inherits visual properties from the original polyline.’, ‘🧹 Deletes the source polyline after a successful leader conversion to keep the drawing clean.’, ‘📌 Processes multiple selected polylines in one run.’, ‘🔒 Uses a locked-selection mode in ssget to avoid editing locked objects.’]
Result:
✅ The result is a faster AutoCAD workflow for converting existing polyline geometry into leader annotation geometry while preserving drafting properties and reducing manual redraw work.
