LaTeX Engineering Document Templates (2026)
Engineering documents mix prose, tables, diagrams and equations — the exact workload LaTeX was built for. These free templates cover design specs, plans and reports across software, systems, hardware and electronics engineering.
Each opens on LetX and compiles in your browser in seconds, with numbered requirements, aligned tables and clean diagrams. Sample content is fictional.

Frequently asked questions
Why write engineering docs in LaTeX?
LaTeX keeps figures, tables and numbered requirements consistent across long documents, and cross-references never break when you reorganise. That is a big win for specs and design documents.
Is there a LaTeX software architecture template?
Yes — our software architecture document template covers context, components, data and deployment views with diagrams and decision records.
Can I make a bill of materials in LaTeX?
Yes — our BOM template uses an aligned, sortable-looking table with part numbers, quantities and costs that stays neat as it grows.
Do I need to install LaTeX?
No — open any template on LetX and it compiles in your browser in seconds, on any OS.
Can my team collaborate on a spec?
Yes — LetX supports real-time collaboration, so a team edits the same document at once, and your work is never used to train AI.
