VportsPoly2Rectang

Short description

πŸͺŸ VportsPoly2Rectang is an AutoCAD and Civil 3D AutoLISP viewport shape conversion manager. πŸ”„ It detects rectangular and polygonal clipped viewports across layouts, supports filters and selection tools, and converts viewport clipping boundaries with undo-aware batch controls.

Command:

πŸš€ Main command: VportsPoly2Rectang
⚑ Alias command: VportShapeConv
🧰 Opens an enhanced DCL manager for detecting, filtering, locking, zooming, and converting rectangular and polygonal clipped viewports.

Description:

πŸͺŸ VportsPoly2Rectang is an SEO-friendly AutoCAD viewport clipping utility for managing rectangular and non-rectangular viewports in paper space layouts.
πŸ” The routine scans layout block table records using VLA iteration, which avoids unreliable ssget layout filtering when inactive layout tabs are involved.
πŸ”„ It identifies polygonal clipped viewports through DXF clip references and non-rectangular viewport flags, then supports converting viewport shape states.
πŸ” It includes lock/unlock status, viewport filtering, select all poly/rect viewport tools, zoom-to-selected, custom clip boundary options, and persisted settings.
🎯 This is useful for layout QA, clipped viewport cleanup, Civil 3D sheet production, and paper space viewport standardization.

Helper function: (if any)​

🧩 VLA layout iteration scans each layout block table record reliably.
🧩 DXF group 340 and DXF 90 bit checks detect non-rectangular clipped viewports.
🧩 Registry helpers persist user settings between sessions.
🧩 DCL builders create the two-panel layout and viewport interface.
🧩 Undo helpers group batch conversion, lock, and unlock operations safely.
🧩 Zoom helpers switch layouts and focus the selected viewport.

Functionalities:

βœ… πŸͺŸ List viewports by layout with rectangular/poly status.
βœ… πŸ” Filter visible viewports by All, Poly only, or Rect only.
βœ… πŸ” Show and modify viewport locked/unlocked state.
βœ… πŸ”„ Convert polygonal viewports to rectangular viewports.
βœ… ✏️ Convert rectangular viewports to custom polygonal clipping boundaries.
βœ… πŸ–±οΈ Select all poly viewports or all rectangular viewports quickly.
βœ… πŸ”Ž Zoom to the selected viewport for visual checking.
βœ… πŸ’Ύ Persist dialog options and clip boundary layer settings between sessions.

Result:

🎯 The result is a controlled viewport cleanup and conversion workflow for AutoCAD and Civil 3D sheet layouts.
πŸͺŸ Users can locate problematic polygonal viewports, lock or unlock viewport sets, convert clipping shapes, and standardize sheets more efficiently.
βœ… The tool improves paper space QA for drawings with many layouts and mixed viewport types.
