Purpose: Automatically connect two open or parallel-like entities and merge them into one continuous polyline Supported objects: LWPOLYLINE, LINE, ARC, SPLINE Usage style: Cleanup or closing gaps between two aligned open objects

Purpose: Duplicate only a chosen segment of a LWPolyline between two picked points and generate it on a selected layer Supported objects: Single LWPOLYLINE only Usage style: Extract partial polyline segments and place them on a different layer using a filterable layer picker dialog

Purpose: Provide a unified dialog interface for running multiple area-processing operations inside closed polylines Use cases: Creating inside boundaries, breaking curves, converting regions to polylines, filtering out open polylines, or joining areas Memory: Stores last chosen option in *BR2P-last-option* and auto-selects it next run

Sort / Purpose: Interactively extend lines, arcs and polylines at both start and end by user defined distances, using a dialog with separate values for each side and safe Apply or Undo control. • Scope: Works on LINE, ARC, LWPOLYLINE and classic POLYLINE entities, handling straight and bulged segments at both ends. • Goal: Provide a flexible Double Extend tool where you can tweak start and end extension, preview the result with Apply, step back with Undo, and only confirm when you are satisfied.

Purpose: Create a simple two vertex centerline between two selected open curves using only their endpoints Supported objects: LINE, LWPOLYLINE, POLYLINE, ARC, SPLINE, ELLIPSE when they are open curves Usage style: Quick central axis between two roughly parallel edges selected as first and last items in a selection set

This AutoLISP routine automates the process of offsetting multiple lines on both sides with customizable distances, profiles, and layer management. It is designed to simplify symmetrical drafting operations by providing an interactive dialog for user control and configuration.

Purpose: Offset curves inward or outward and assign the results to a selected layer Supported geometry: *POLYLINE, ARC, CIRCLE, ELLIPSE, SPLINE (planar only) Session memory: Remembers last offset distance, last chosen layer, and last direction for faster repetitive usage

Purpose: Convert REGION objects into closed LWPOLYLINEs while preserving curve continuity and arc bulges Typical use: Cleanup of Boolean-created geometry or boundary extractions that output REGION entities Input object: REGION only — all selected REGIONs are processed Output format: Clean, closed LWPOLYLINE with correct bulges and segment ordering
