What an Engineering Drawing Contains
A typical engineering drawing for machinery fabrication packs dense information into an otherwise graphic sheet. Alongside the visual geometry, the drawing carries material choices, manufacturing notes, reference standards, and identification data. When you ask Lekhak’s AI typing to extract the text layer, it pulls exactly that written content: the title block, bill of materials, call‑outs for welding and finish, and any compliance‑plate fields, leaving the drawing itself behind.
Title Block and Bill of Materials
The title block holds the document’s identity: drawing number, revision level, date, scale, and often the organisation or design office that created it. Adjacent to it, the bill of materials (BOM) lists part numbers, descriptions, quantities, and material call‑outs. Drawings for handling equipment such as tote bins or bag splitters may also flag the safe working load directly in this zone. Lekhak’s typed DOCX captures all these fields as editable text, preserving the referencing structure that the workshop or quality‑control team needs.
Technical Specifications and Standards
Beyond the identification area, a fabrication drawing typically includes detailed specifications: aluminium construction or steelwork grades, welding symbols and procedure references, surface‑preparation notes, and painting specifications. In some cases a separate compliance plate is defined, listing material certifications, design codes, and safe working load. All these written annotations, including any standards references, are extracted and placed in the DOCX so you can search, copy, and share them without manual re‑typing.
Why Manufacturing Teams Type Out Legacy Drawings
Many fabrication shops hold decades of paper blueprints or scanned PDFs whose text is locked inside an image. Converting those legacy drawings into a typed, editable DOCX saves time across estimating, ERP data entry, and vendor communication. A buyer preparing a request for quotation can pull the complete material specification and welding requirements straight into the tender document, while the quality‑control department can build a digital inspection checklist from the drawing’s finish notes. The structure of a standard ISO 128‑style drawing means the typed extract follows a recognisable order, which makes it easy to slot into existing document management systems.
AI Typing vs. Manual Transcription: What Fits Your Workflow
Lekhak’s AI typing delivers a clean DOCX in minutes, ideal for internal routing and digital records. A manual, hand‑keyed approach still has its place when an official certified version of the document is needed, especially where a chartered engineer’s stamp or notarisation is required. The best route depends on where the typed content goes next.
When AI-Powered Typing Is Enough
Most everyday manufacturing tasks are well served by an instant extract. Creating a bill of materials for an ERP upload, populating an inspection report, drafting a request for quote, or simply archiving a searchable copy of a scanned drawing all fall squarely within the AI typing’s capability. The output preserves dimensions, material grades, welding call‑outs, and finish instructions as editable text, so downstream teams can reuse the information without touching the original paper.
When a Formal Manual or Certified Version May Be Required
Certain contractual, regulatory, or legal situations demand more than a straightforward extract. If a drawing becomes part of a patent filing, a safety‑case submission, or a contractual dispute, you may need a certified copy endorsed by a chartered engineer or a notarised version that confirms the document is a true copy of the original. Lekhak’s AI typing is a best‑effort extract; it does not itself issue a certification. For those higher‑assurance scenarios, the typed DOCX can serve as a working draft before an engineer or notary reviews and stamps a final copy.
What Lekhak’s AI Typing Service Produces
When you upload a PDF or image of a technical drawing, the platform returns a single DOCX file that contains all the textual and dimensional information it could recognise. Material grades (for aluminium, steel, or other alloys), welding symbols written as text, painting specification notes, safe working load values, and compliance‑plate fields appear as editable blocks. The graphical layout and linework are not reproduced; you get the written content arranged in a logical order that follows the drawing’s structure. Because the whole process runs in minutes, multiple sheets can be processed back‑to‑back without a queue, giving you a full assembly‑level specification set in a single sitting.
When You Need a Certified or Notarised Copy of a Technical Document
For a drawing that must be submitted to a foreign regulator or used in a legal proceeding, the typed extract from any automated service is unlikely to satisfy the receiving authority on its own. A certified copy usually requires a professional engineer’s signature and stamp, while notarisation confirms the authenticity of the reproduction. Apostille, governed by the Hague Apostille Convention and handled in India by the Ministry of External Affairs, may follow for cross‑border use. Lekhak’s AI typing gives you the editable foundation; the subsequent certification and legalisation steps are separate acts that you arrange through a qualified engineer, a notary public, or the relevant government authority.
Indian Standards and Codes Commonly Referenced
Drawings originating from Indian workshops frequently cite Bureau of Indian Standards codes for materials, welding, and surface protection. These references appear in the notes block or beside material call‑outs. The table below summarises the categories most often encountered on fabrication and assembly drawings.
| Category | Typical Contents | Where Referenced on Drawing |
|---|---|---|
| Structural steel | Grades, rolling tolerances, Indian Standard designations | Bill of materials, material notes |
| Welding | Process standards, electrode specifications, acceptance criteria | Welding symbol call‑outs, general notes |
| Surface preparation and painting | Blast‑cleaning grades, primer and top‑coat specifications | Finish schedule, painting specification block |
While the AI typing preserves these codes as editable text, it is up to the user to verify that the latest revision of each standard is still applicable to the project.
How to Get a Duplicate if the Original Drawing Is Lost
Lost paper originals are common in long‑running machinery projects. The first practical step is to contact the design office or the original equipment manufacturer; most retain digital archives of released drawings. If the organisation no longer exists, project archives at client or contractor offices may hold copies. When even those avenues run dry, a high‑resolution scan of a well‑preserved print can be enough for AI typing to recover the text layer and create a fresh editable DOCX, effectively reconstructing the specification even without the original master.
Frequently Asked Questions
Can I upload a hand‑drawn sketch for typing?
Yes, the service accepts hand‑drawn sketches as long as the image or PDF is clear. Legibility of handwritten dimensions and notes directly affects the accuracy of the output; cleaner originals produce better results.
Will the DOCX preserve dimensions, notes, and welding symbols as editable text?
Dimensions, fabrication notes, and welding symbols written out as text or standard notations are captured. Symbol graphics that represent an entire weld symbol without a text equivalent may be omitted, but all textual call‑outs appear in the DOCX.
Does the typing output show the exact layout of the original drawing?
No, the DOCX contains the extracted text arranged in a logical reading order. The graphical layout and linework are not reproduced. The document is designed for reuse in specifications and databases, not for redrawing.
What formats can I upload, scanned PDFs, photos, blueprints?
You can upload PDF, JPG, PNG, WebP, and TIFF files. Clear, flat scans with high contrast give the best recognition for dimensions and fine print.
How long does the typing take?
A typical single‑sheet drawing is processed in minutes. Complex multi‑sheet sets may take longer, but there is no per‑job queue and you can start another upload immediately.
Is the typed document suitable for government or regulatory submissions?
Lekhak’s typing is a best‑effort digital extract, not a certified copy. For regulatory or court filings you will often need a certified or notarised version prepared by a chartered engineer or a notary public.
Does Lekhak provide notarised or certified typing?
No. The self‑serve AI typing output is an editable DOCX, not a certified or notarised document. When a formal certified copy is required, you can use the typed output as a draft and have it reviewed and stamped by an engineer or notary separately.
Can the AI recognise handwritten dimensions and notes?
It can handle handwritten text to a reasonable degree, but neat, block‑letter writing yields higher accuracy. Heavily cursive or smudged handwriting may require a quick manual check after extraction.
Does Lekhak’s typing work for drawings with text in regional Indian languages?
Yes, the platform supports typing from 22 Indian languages and over 70 global languages. If a drawing contains bilingual call‑outs, the DOCX will retain both language layers.
Is there a file‑size or page limit per upload?
There is no rigid page limit; the credit‑based pricing model scales with the number of pages processed. You can check current rates at lekhak.app/pricing.
