🧪 The file also provides DEX and DEXDEBUG aliases for the main tool and its diagnostic report.

🧩 MiddleLinePolylines provides the CPL command for creating a centerline between two selected open AutoCAD curves.
📐 The current version accepts general open vlax curve objects such as LINE LWPOLYLINE POLYLINE SPLINE and ARC rather than only polylines.
🧠 The algorithm uses temporary curve copies offsets lofted geometry and geometric intersection processing to derive the middle path.

🧩 MiddleLinePolylines_2 provides the CPL_2 command for generating a simple two vertex centerline between two open curves.
📍 The routine averages the start points of the first and last selected curve and averages their end points.
📐 A new two vertex LWPOLYLINE is created in ModelSpace from those two midpoint positions.

🧩 MultiOffsetBothSidesWithLayer is the M_07 C# AutoCAD and Civil 3D offset project for generating structured left and right parallel geometry from selected centerline objects.
🎛️ The current project uses a modeless WinForms interface with profiles pipe counts left and right offsets extra ducts target layers closing centerline source handling live preview Apply and Undo last controls.
📦 The current source build number is 1.0.006 and the physical Visual Studio project name is shortened to MOBSWLE.

🧩 OffsetAndLayer offsets selected planar curve objects inward or outward by a chosen distance and assigns the new offset geometry to a selected drawing layer.
🎛️ A DCL dialog provides Inward or Outward direction offset distance layer name filtering and a layer dropdown.
💾 The last offset value selected layer and direction are stored in the AutoCAD environment for reuse.

🧩 ParallelPolylinesOption is a DCL utility for closing two parallel open curves into one joined polyline or reopening a closed lightweight polyline into two parallel open sides.
➗ Both close and unclose workflows can automatically generate a midpoint centerline polyline on layer _HILFSLINIEN.

🧩 SelectStraightEntities automatically finds and selects orthogonal LINE LWPOLYLINE and POLYLINE geometry in the current AutoCAD layout.
📐 Accepted segments must run at approximately 0 90 180 or 270 degrees and lightweight polylines must contain no bulged arc segments.
🚫 Geometry on layer PAGE_LIMIT_02 is explicitly excluded.

Purpose: Label slopes between two picked points using multiple numeric and ratio formats Scope: Works entirely in 2D, producing TEXT entities placed and rotated along the measured segment Workflow: Configure options in a dialog (DCL), then pick two points repeatedly to place slope labels Output style: Percent, H:V integers, V:H integers, H:V decimals (x.xx:1), or V:H decimals (1:x.xx) Defaults: Below=No, Height=1, H=1, V=1, Precision=2, Format=%
