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

Sort / Purpose: Create a new polyline segment copied between two picked points on an existing LWPOLYLINE, place it on a chosen layer, and optionally extend, rotate, move, and generate multiple offset copies via an interactive dialog with Apply and Undo. • Scope: Works only on a selected LWPOLYLINE, extracting the portion between two points along the polyline and building a new, separate polyline from that segment. • Goal: Speed up creation of repeated pipe or band segments with controlled layer assignment, geometric extension at ends, rotation, perpendicular distance, and multiple parallel offsets using presets.

XrefLayers is a single-window tool to manage XREF insert layers: create per-XREF target layers, assign inserts to target layers, force all XREFs onto one existing layer, and zoom to a selected XREF extents.

• Goal: Manage how external references (XRefs) are reassigned to layers in the current drawing.
• Modes: Either move all XRefs to a single _XREF layer or move each XRef to its own 0-XREF_<XRefName> layer.
• User experience: Presents a DCL dialog with radio buttons and remembers the last selected option for the next run.

• Purpose: Provides a DCL dialog to reorder XREF draw order from Top to Bottom, then applies that order safely using the DRAWORDER command.
