THR

Status

What it is

THR is tracked as a ThreadWorks embroidery format lead. It appears to be closer to a vector/native embroidery design format than a simple machine stitch stream.

Satin Studio behavior

Satin Studio documents this format for identification and inspection. It does not open or export the file.

Versions and variants

Unknown.

File identification notes

Reported descriptions call THR a full vector embroidery format for ThreadWorks software.

Observed structure notes

• THR remains a vector/native embroidery lead. No reliable byte structure is established here.
• Compatibility checks compare object semantics, not only extracted stitches.

Structure sketch

THR is a vector/native embroidery lead, not a confirmed machine stream.

struct ThrCandidate<'a> {
    version_or_header: &'a [u8],
    vector_objects: &'a [ThrObject<'a>],
}

struct ThrObject<'a> {
    object_kind: Option<&'a str>,
    payload: &'a [u8],
}

Compatibility evidence

The notes above help identify and inspect the format; they do not imply import or export support. Keep the original file and record the machine and software that produced it.
