Advanced layout viewport functionality, including non-rectangular viewports, clipping, and comprehensive MVIEW/VPCLIP commands.

Technical Positioning
Full AutoCAD-like layout viewport capabilities, supporting complex drawing presentations and precise control over model space display in paper space.
SaaS Insight & Market Implications
The current limitation to rectangular viewports and missing advanced MVIEW/VPCLIP features significantly restricts CADCraft's utility for professional drawing layouts. Complex presentations often require non-rectangular or clipped viewports to highlight specific design elements. The absence of these features, along with critical controls like viewport locking and scaling, forces users into cumbersome workarounds or prevents them from producing industry-standard output directly within CADCraft. This gap directly impacts the product's ability to serve as a complete AutoCAD alternative, particularly for final documentation and plotting, hindering its market competitiveness for users requiring sophisticated layout capabilities.

Raw Developer Origin & Technical Request

Source Icon GitHub Issue Oct 11, 2026
Repo: storytold/cadcraft
feat(layout): polygonal, object and clipped viewports, MVIEW Lock/ON/OFF/Fit/2/3/4, VPCLIP, viewport scale (gaps.md F15)

## Summary
Layout viewports are limited to rectangles (`docs/gaps.md` F15). Missing:
- polygonal, object and clipped viewports;
- MVIEW's Lock, ON/OFF, Fit, Restore and 2/3/4 options;
- VPCLIP;
- a viewport scale control in the UI.

## Scope
- MVIEW: Polygonal (pick vertices, with Arc segments where it fits), Object (convert a closed polyline, circle, ellipse, spline or region into a viewport boundary), Lock On/Off, ON/OFF, Fit, Restore (from named viewport configurations if VPORTS exist; otherwise "not available yet"), 2/3/4 viewports, with both the typed form and the JSON form.
- VPCLIP: clip an existing viewport with an object or a polygon, and Delete to remove the clip.
- Clipped viewports: render model space clipped to the boundary on screen and in PNG/SVG/PDF plots. A locked viewport refuses zoom and pan inside it.
- DXF: viewport clip boundary handle (group 340), status flags (90: locked, non-rectangular clipping, on/off), round trip per the public DXF Reference.
- UI: a viewport scale list on the status bar for the active viewport, kept thin.
- Programmatic calls never open dialogs.

## Expected
Viewports behave like publicly documented AutoCAD layout viewports.
