Short description

🧩 All_inside provides the WPS command for selecting drawing objects located inside selected circles and lightweight polylines.
🪟 The routine builds Window Polygon selection boundaries from each selected bounding object and combines the detected interior objects into the final selection set.
📦 After selection the user can optionally create an AutoCAD group containing the bounding objects and the objects found inside them.

Command:

Main command: WPS

Description:

⭕ For a selected circle the routine approximates the circular Window Polygon boundary with 90 points at four degree intervals.
📐 For a selected LWPOLYLINE the routine sends its DXF group 10 vertices to the AutoCAD WP selection option.
🔗 Results from multiple bounding circles and polylines are accumulated into the active selection set.
➕ The selected boundary objects themselves are added to the resulting set.
📦 The final prompt offers Yes or No for creating an AutoCAD group from the complete set.
🧭 The source comments reference CADStudio CADforum and a CADTutor discussion about selecting objects inside multiple polylines.

Helper function: (if any)

SELECT with the WP option performs the inside selection.
polar generates circle boundary points.
ssget and ssadd build and combine selection sets.
.-GROUP creates the optional final group.

Functionalities:

✅ Multiple boundary selection – accepts more than one circle or lightweight polyline.
✅ Inside object selection – uses AutoCAD Window Polygon selection to find contained objects.
✅ Circle boundary approximation – builds a 90 point polygon around each selected circle.
✅ Polyline boundary support – uses LWPOLYLINE vertices as the polygon boundary.
✅ Combined result selection – merges objects found inside all selected boundaries.
✅ Boundary inclusion – keeps the bounding circles and polylines in the final selected set.
✅ Optional group creation – offers creation of an AutoCAD group from the resulting set.

Result:

🎯 The result is one active selection set containing the chosen boundaries and objects found inside them.
📦 The user can optionally preserve the complete selection as an AutoCAD group.
