About this asset

DWG Loader brings native AutoCAD DWG and DXF support directly into your Unity project — ideal for BIM viewers, factory layouts, mechanical design review, GIS/CAD overlays, training simulators, and any app that needs accurate 2D engineering drawings inside a 3D scene.

Load drawings at runtime or import them in the Editor. Geometry is batched into efficient meshes with per-entity pick IDs, so you can interact with individual lines, arcs, polylines, hatches, blocks, and text without spawning one GameObject per entity.

Online Demo

Key capabilities:

• Runtime and Editor loading (sync and async with frame-spread build for large sheets)

• Accurate 2D display: lines, fills, hatches, dashed/chain line styles, dimensions, blocks, and TextMeshPro labels (CJK-friendly)

• Supports 3D DWG and DXF files

• Layer visibility control at runtime

• GPU entity picking: click, tolerance pick, rectangle box-select, and selection highlight

• Orthographic pan/zoom camera helpers for CAD-style navigation

• Export to DXF, DWG, PDF, and BMP from code or Editor menus

• Five ready-to-run sample scenes covering import, async load, single pick, box select, and export

Rendering pipelines are detected automatically — Built-in, URP, and HDRP shaders are included. The package ships with a Windows x64 native plugin and sample CAD files. No legacy CAD Import dependency; integrate with a few lines of C# or use the provided examples.

Technical details

Features

• Native DWG/DXF read via DwgLoaderNative.dll (Windows x64)

• Supports native WebGL reading of DWG/DXF

• Entity types: lines, arcs, polylines, circles, ellipses, splines, hatches/solids, blocks/inserts, dimensions, TEXT/MTEXT (TMP)

• Line styles: solid, dashed, dotted, chain; hatch section lines and stipple fills

• Layer list with runtime show/hide API

• GPU color-ID picking (click, tolerance, rectangle select) + selection overlay highlight

• Text and filled-region bounds picking for reliable box-select

• Async load API (DwgDocument.LoadAndBuildAsync) with configurable frame-spread mesh build

• Export: DXF, DWG, PDF, BMP (DwgExport + Editor menus)

• Editor: File → Import DWG-DXF, smoke tests, geometry regression, performance benchmarks, Standalone build helpers

• Sample scripts: SimpleLoadExample, AsyncLoadExample, EntityPickExample, ExportExample

• 5 demo scenes under Assets/DWG Loader/Scenes/

Rendering

• Built-in Render Pipeline (default)

• Universal Render Pipeline (URP) — dedicated line/pick/highlight shaders

• High Definition Render Pipeline (HDRP) — Unlit CAD-color line rendering

• Automatic pipeline detection (DwgRenderPipeline.Detect); no hard URP/HDRP assembly dependency in core Runtime

Supported platforms

• Windows Editor (x64)

• Windows Standalone Player (x64)

• macOS / Linux / mobile: not supported in this release (native plugin is Win64 only)

Requirements

• Unity 6000.3.x or compatible (tested on 6000.3.8f1)

• TextMeshPro (included with Unity)

• URP/HDRP: install the corresponding SRP package in your project; copy Assets/DWG Loader into that project

Documentation

• In-package: Assets/DWG Loader/Document/README.md

• URP/HDRP setup: Assets/DWG Loader/Document/URP_HDRP_Validation.md

Third-party

• Earcut polygon triangulation (ISC License) — see Third-Party Notices.txt
