cadmpeg-codec-catia

cadmpeg-codec-catia opens .CATPart files and loads available model data into CadIr. It recognizes the known V5_CFV2 storage layouts and reads analytic geometry, spline geometry, and topology where the file records provide the needed links.

Install

cargo add cadmpeg-codec-catia cadmpeg-ir

Use

use cadmpeg_codec_catia::CatiaCodec;
use cadmpeg_ir::{Codec, DecodeOptions};
use std::fs::File;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut input = File::open("part.CATPart")?;
    let result = CatiaCodec.decode(&mut input, &DecodeOptions::default())?;

    println!(
        "{} bodies, {} surfaces",
        result.ir.model.bodies.len(),
        result.ir.model.surfaces.len()
    );
    Ok(())
}

CatiaCodec::inspect identifies the storage layout and lists its logical streams without decoding geometry.

Coverage

Standard nested files have the broadest coverage, including connected B-rep topology when trim and endpoint records resolve. Other layouts currently yield smaller sets of analytic or spline geometry.

The crate does not yet read tessellation, design history, assemblies, appearances, or persistent attributes, and it does not write .CATPart files. See format support for the detailed matrix.
