Convert .tcd to AutoCAD Format

I have a single .tcd file that I need opened and converted into a format that AutoCAD can read—DXF is ideal, but DWG or another widely-supported option is fine too. The drawing is for architectural design work, so accuracy matters.

I’m not certain whether the original file contains multiple named layers; if it does, handle them in the most practical way to keep the drawing usable in AutoCAD. What I definitely need preserved are the annotations, dimensions, and any custom line styles, so please make sure those come through intact.

Deliverable
• A clean, ready-to-open DXF (or equivalent) that retains all annotations, dimensions, and line styles from the source file.

That’s all—once I can drop the file straight into AutoCAD and see everything as expected, the job is complete.
