Edge Shaping

New shapingEdges(_:matching:) cuts or fills a symmetric cross-section (chamfer or fillet) along the edges of a 3D geometry, selected by criteria rather than hand-picked by side/corner:

Box(10).shapingEdges(.fillet(radius: 2), matching: .along(.z))

• EdgeShape describes the cross-section: .chamfer(depth:), .chamfer(width:), .fillet(radius:), .fillet(depth:), or a fully custom profile via .custom(name:parameters:curve:).
• EdgeQuery composes selection criteria: sharpness range, convexity (.convex/.concave), open/closed, length, direction (along/parallel/perpendicular), spatial bounds (within), and an arbitrary mask shape (within(mask:)).
• withMaxTurn(_:) controls how sharply a chain of segments can bend and still count as one continuous edge (default 45°).
• readingEdges(matching:) exposes the matched edges (position, direction, dihedral angle, convexity) for programmatic use and filtering; visualizingEdges(matching:)/visualizingEdges(_:) adds a debug visualization of a selection.

This is a first release of edge shaping. It covers a lot of ground already, but you may still run into rough edges (pun intended) on some geometry. Expect it to keep improving. If you find a case that doesn't work well, please file an issue.

Additions

• Import can import a single element (by id) and its descendants from an SVG file, skipping the rest of the document.
• withoutMaterials() removes all colors/materials previously applied anywhere within a geometry's subtree.
• evaluating(_:) lets you perform several geometry reads (bounds, outlines, etc.) inside one async closure via a GeometryEvaluator, instead of nesting single-purpose readers.

Improvements

• Environment directives set inside a Model builder are now visible to @Environment reads directly inside that same builder, instead of only affecting geometry built afterward.
• Geometry evaluation is significantly faster across the board. 3MF export is 3-5 times faster.
• Fixed occasional mesh defects at edge-profile seams and sharp vertices in cuttingEdgeProfile/formingEdgeProfile, which is also now up to 5x faster.
• Improved SVG font handling.
• swept(along:) no longer squishes the cross-section at sharp corners in the path; corners are now mitered so the swept surface keeps a consistent width through the bend.

Bug fixes

• SVG export now properly declares width/height in millimeters.
• Metadata (license, date, application) can now be overridden when combining multiple option sources; a more specific value was previously discarded in favor of an earlier one.
• Fixed curve subcurve extraction (e.g. curve[..<x]) with an upper-bound-only range returning the wrong bounds instead of resolving against the curve's domain.
