Crate acadrust 

acadrust

A pure Rust library for reading and writing CAD files in DXF and DWG formats.

acadrust provides comprehensive support for both file formats with a focus on correctness, type safety, and completeness. Inspired by ACadSharp, it brings full-featured CAD file manipulation to the Rust ecosystem.

Highlights

• DXF — Read and write ASCII and Binary DXF (R12 through R2018+)
• DWG — Read and write native DWG binary files (R13 through R2018+)
• 41 entity types, 9 table types, 20+ non-graphical objects
• Type safe — strongly-typed entities, tables, and enums
• Failsafe mode — error-tolerant parsing that collects diagnostics
• Encoding support — automatic code page detection for pre-2007 files

Quick Start — DXF

use acadrust::{CadDocument, DxfReader, DxfWriter};

// Read
let doc = DxfReader::from_file("input.dxf")?.read()?;
println!("Entities: {}", doc.entities().len());

// Write
DxfWriter::new(&doc).write_to_file("output.dxf")?;

Quick Start — DWG

use acadrust::{CadDocument, DwgReader, DwgWriter};
use acadrust::entities::*;
use acadrust::types::Vector3;

// Read
let doc = DwgReader::from_file("input.dwg")?.read()?;

// Create and write
let mut doc = CadDocument::new();
let line = Line::from_coords(0.0, 0.0, 0.0, 100.0, 50.0, 0.0);
doc.add_entity(EntityType::Line(line))?;
DwgWriter::write_to_file("output.dwg", &doc)?;
