dxf-vuer@2.2.0

Features

• Touch support: touch-action: none on .dxf-viewer container for correct mobile touch handling
• GIS origin offset: uses originOffset from dxf-render instead of group.position shift for correct large-coordinate handling

Refactored

• Import useControls instead of deprecated useOrbitControls

Dependencies

• Requires dxf-render ≥ 1.2.0

Install

npm install dxf-vuer@2.2.0

Full changelog: https://github.com/arbaev/dxf-kit/blob/main/packages/dxf-vuer/CHANGELOG.md

dxf-render@1.2.0

Features

• Variable-width polylines: POLYLINE/LWPOLYLINE per-vertex startWidth/endWidth tapering with triangle-strip mesh geometry and miter joins
• GIS origin translation: $EXTMIN/$EXTMAX center subtracted from coordinates before Float32Array to prevent precision loss at large GIS coordinates (UTM, state plane); originOffset returned from createThreeObjectsFromDXF()
• Touch support: switched from OrbitControls to MapControls for native one-finger pan on mobile devices

Refactored

• useOrbitControls renamed to useControls (old name kept as deprecated alias)

Examples

• New examples/leaflet-dxf/ — overlay DXF on OpenStreetMap with geo-referencing (parser-only, DXF → GeoJSON)
• New examples/dxf-to-pdf/ — export DXF drawings to PDF via Three.js offscreen rendering + jsPDF
• New "Line Types & Widths" showcase sample on demo landing page
• Examples section added to demo landing page with StackBlitz links

Install

npm install dxf-render@1.2.0

dxf-vuer@2.1.0

Features

• Theme-adaptive layer colors: layer panel now correctly inverts ACI 250-251 gray colors in dark mode via resolveThemeColor().

Bug Fixes

• sRGB color output: added OutputPass to the post-processing pipeline for correct linear→sRGB color conversion.
• Three.js addon imports: updated import paths from three/examples/jsm/ to three/addons/ for Three.js 0.182 compatibility.

Dependencies

• Requires dxf-render ≥ 1.1.0 (new resolveThemeColor export).

npm: https://www.npmjs.com/package/dxf-vuer/v/2.1.0

dxf-render@1.1.0

Features

• Theme-adaptive ACI 250-251: dark gray colors (ACI 250, 251) now invert to light grays in dark mode, keeping them visible against dark backgrounds. New exports: isThemeAdaptiveColor(), resolveThemeColor().

Bug Fixes

• Single-point polyline: polylines with a single vertex are now rendered as points instead of being silently skipped.
• Layer default visibility: layers now default to visible: true, frozen: false, locked: false when flags are not explicitly set in the DXF file.
• Three.js addon imports: updated import paths from three/examples/jsm/ to three/addons/ for Three.js 0.182 compatibility.

npm: https://www.npmjs.com/package/dxf-render/v/1.1.0

v1.5.0

Legacy release. This is from the single-package era (dxf-vuer v1.x). The project has since been split into two packages: dxf-render and dxf-vuer v2.x. See latest releases.

Highlights

• TAA anti-aliasing — thin crisp lines during interaction, smooth text and edges after idle accumulation (32 frames, ~0.5s)
• Instant dark mode — theme switching without re-render via material-level color sentinel
• Overlay rendering — text and dimension arrows always render on top of drawing geometry
• Major refactoring — monolithic 2622-line file replaced by 15 modular entity collectors

Added

• TAA anti-aliasing via EffectComposer + TAARenderPass: hardware MSAA disabled (thin lines), 32 jittered frames accumulated when idle for smooth text and edges
• Instant dark mode switching — MaterialCacheStore.switchTheme() updates theme-dependent materials in-place, no re-parsing needed
• Overlay mesh buffer in GeometryCollector for text glyphs and dimension/leader arrows, rendered last
• Hatch style support (code 75): Normal (even-odd), Outer (level 0+1), Ignore (level 0 only)
• Leader arrow size from XDATA DSTYLE override

Fixed

• Hatch: CW arc edges angle inversion for proper boundary connectivity
• Hatch: nearly-full-circle arcs from incorrect ccw flag clamped to short arc
• Hatch: polygon centroid for even-odd nesting test instead of first vertex
• Dimension text angle: while loop for normalization fixes upside-down text >270°
• Dimension arrows: DIMSTYLE DIMTSZ=0 now correctly overrides header $DIMBLK=ARCHTICK
• Leader arrow angle computed from spline at arrowSize distance
• MTEXT word wrap: width/height ratio threshold filters artifact micro-widths

Changed

• Architecture: useDXFGeometry.ts (2622 lines) → 15 entity collector modules in geometry/collectors/
• Color resolution uses ACI7_COLOR sentinel for deferred dark/light theme resolution
• Three separate material Map caches → MaterialCacheStore with switchTheme(), disposeAll()
• useThreeScene manages EffectComposer lifecycle for TAA
• 841 tests across 36 files

dxf-vuer@2.0.1

Changed

• Repository renamed from dxf-vuer to dxf-kit
• Updated all repository links, homepage, and documentation

No code changes.

📦 npm

dxf-vuer@2.0.0

dxf-vuer 2.0.0 — Monorepo Split

Vue 3 wrapper extracted into a thin layer on top of dxf-render.

Breaking Changes

• New peer dependency: dxf-render >= 1.0.0 required
• Parser entry moved: dxf-vuer/parser → dxf-render/parser

Backward Compatibility

All existing imports from dxf-vuer continue to work — the package re-exports everything from dxf-render:

import { parseDxf, DXFViewer } from 'dxf-vuer'  // still works

Install

npm install dxf-vuer dxf-render three

dxf-render@1.0.1

📦 npm

dxf-render@1.0.0

dxf-render 1.0.0 — Initial Release

Framework-agnostic DXF parser + Three.js renderer, extracted from dxf-vuer v1.5.0 into a standalone package.

Highlights

• Custom DXF parser — 25 entity handlers, zero external dependencies
• Three.js renderer — 21 rendered entity types with geometry merging, block template caching, time-sliced rendering
• Two entry points: dxf-render (full API) and dxf-render/parser (parser only, zero deps)
• parseDxfAsync() — Web Worker parsing with automatic fallback
• Vector text — opentype.js triangulated glyphs, Liberation Sans/Serif fonts
• Linetype & hatch — geometric pattern splitting, 25 built-in AutoCAD hatch patterns
• TAA anti-aliasing, instant dark mode, overlay rendering
• Full TypeScript declarations

Install

v1.4.0

Legacy release. This is from the single-package era (dxf-vuer v1.x). The project has since been split into two packages: dxf-render and dxf-vuer v2.x. See latest releases.

What's New

New Entity Types (+5 rendered)

• MLINE — multiline entities with multiple parallel line elements
• XLINE — construction lines (infinite in both directions), clipped to drawing extents
• RAY — rays (infinite in one direction), clipped to drawing extents
• HELIX — parsed as SPLINE, rendered through the existing spline pipeline
• ATTDEF — attribute definitions now rendered as text (previously parse-only)

Total rendered: 21 types (was 16), plus ATTRIB within INSERT blocks.

New Features

• DIMSTYLE table — 40+ dimension variables fully parsed (DIMBLK, DIMSCALE, DIMTXT, etc.)
• Architectural units — dimension text in feet-inches notation (DIMLUNIT=4) with fractions
• Architectural ticks — oblique tick marks for dimension lines (DIMTSZ > 0)
• Text underline — MTEXT \L...\l formatting rendered as line segments
• Tab support — MTEXT tab characters rendered with 4×textHeight tab stops
• 3D polygon mesh — POLYLINE with is3dPolygonMesh as wireframe grids
• PDMODE 34 — cross-in-circle point symbols
• $MIRRTEXT — mirrored text in blocks with negative X scale
• INSUNITS — $INSUNITS header + getInsUnitsScale() utility
• 3DSOLID parser — parsed (not rendered), data stored for future use
• BLOCK_RECORD table — handle-to-name mapping

Bug Fixes (30+)

• Dimension lines: rotated, angular, overshoot, text gap, radial/diametric placement
• Text: height from DIMSTYLE, leading spaces, \H format, textSize parameter
• Hatch: solid fill 86× faster on large files, spline edges, donut shapes
• MTEXT: O(n) word wrapping, tab indentation
• Polyline: bulge=1 arcs, closed LWPOLYLINE, polyface mesh
• Ellipse: arc sweep direction, OCS transform
• Linetype: pattern scaling, auto-LTSCALE
• Leader: path type, tick marks, arrow sizing
• 3D entities: parsing robustness
• DXF files without TABLES section

Changed

• Fonts: Noto Sans/Serif Light → Liberation Sans/Serif Regular (Arial/Times New Roman metrically compatible)
• Entity parsers: 22 → 25 handlers (mline, xline, 3dsolid)
• Tests: 648 → 789 cases across 34 files
