AI-assisted engineering automation that interprets 2D drawings (DWG/DXF/PDF), applies approved deterministic engineering rules, and generates parametric 3D CAD models, thermal validations, and fabrication-ready deliverables in minutes.
In engineered-to-order manufacturing and heavy process fabrication, your best engineers spend over 35% of their working hours on repetitive drawing recreation and manual calculations rather than creative engineering.
Incoming customer drawings arrive in disparate 2D formats (DWG, DXF, scanned PDFs). Draftsmen spend 15 to 20 hours per tender manually tracing lines, redefining coordinate boundaries, and building 3D models from scratch.
Critical refractory lining recipes, thermal conductivity curves, anchor pitch formulas, and ASME Section VIII / API 560 rules are trapped in legacy spreadsheets, printed binders, and senior engineers' minds.
When customer process parameters shift, updating dependent wall thicknesses, insulation grades, and anchor schedules requires manual recalculation across multiple disconnected spreadsheets and 2D layouts.
Proprietary pressure vessel geometries, furnace drawings, and tender specifications cannot risk exposure to commercial cloud LLMs that log training tokens or leak intellectual property outside your firewall.
This platform is not a simple 2D-to-3D converter. It orchestrates drawing intelligence, deterministic physics equations, parametric geometry, and automated shop deliverables under licensed engineer oversight.
Accepts AutoCAD DWG, DXF, vector PDF, and scanned engineering drawings. Advanced vectorization algorithms clean noise, isolate title blocks, and decompose layered geometry without requiring manual CAD pre-processing.

Proven in refractory vessels and expandable across heavy process equipment where parametric CAD, deterministic physics, and accurate BOM takeoff are paramount.
Interprets shell diameter, operating temperatures (up to 1,400°C), and process gas profiles. Automatically computes multi-layer refractory thickness (working brick + castable backup + calcium silicate board), verifies shell skin temp <80°C, and details anchor stud spacing.
Extracts hopper angles and material flow trajectories. Automatically segments liner plates for standard crane handling weights, optimizes fastener drill patterns, and generates shop cutting layouts that minimize plate remnant scrap.
Extracts high-pressure piping schematics, vessel nozzles, and insulation class specifications. Automates multi-layer mineral wool / aerogel sizing, computes surface heat loss, and generates sheet-metal jacketing cut developments.
Extracts equipment footprints and ventilation requirements. Automates sheet metal panel unfoldings, bend deduction allowances, louvre cutouts, and synchronized enclosure BOMs.
Interprets plant elevation profiles and conveyor centerline runs. Configures standardized drive frames, idler spacings, safety guards, and structural connection details.
Generates parametric models for internal trays, vortex breakers, demister supports, and square-to-round heavy sheet-metal duct transitions with automated weld schedules.
In heavy engineering, probabilistic chatbots hallucinate coordinates and violate thermal limits. Zero Zeta’s "Glassbox" architecture separates cognitive drawing perception from deterministic physics solvers.

|---|---|---|
| Workflow Pipeline |
Transparent Process Complete 7-step traceable pipeline: Multi-format Ingestion → Computer Vision Extraction → Structured Engineering Knowledge Graph → Domain Rules → Parametric CAD → Deterministic Validation → Deliverables Takeoff. |
Proprietary Core Zero Zeta's proprietary computer-vision neural weights, boundary extraction heuristics, and specialized geometric decomposition algorithms remain protected. |
| Engineering Rules & Codes |
Deterministic Standards Standards explicitly verified and cited: ASME Section VIII Div 1/2, API 560, and ASTM C Refractory Standards. All thermal conductivity equations run on classical mathematical solvers. |
Protected Solvers Internal finite-element thermal solver scripts and custom RAG chunking vector topologies are retained as proprietary software IP. |
| Safety & Approval |
Guaranteed Oversight No autonomous engineering sign-off. Every design requires explicit review, parameter adjustments, and formal lock by your qualified Professional Engineer. |
Enterprise Perimeter Your private engineering design rules, internal tolerance matrices, and proprietary client drawing archives never leave your firewall. |
| Deployment & Cloud Egress |
Zero Cloud Egress Deployable fully on-premises or within a private VPC. No drawings, dimensions, or prompt tokens are ever sent to public cloud LLM vendors. |
Strict NDA Compliance Zero Zeta maintains strict anonymization protocols. Client identities, specific project geometries, and national identifiers are never made public. |
Deployed with a multinational heavy industry and refractory equipment leader handling complex industrial calciner and vessel designs.
The client’s pre-bid engineering department handled an average of 40 complex vessel tenders per month. Each quote required an estimated 20 engineering hours of manual drawing transcription, multi-layer thermal resistance modeling, anchor stud detailing, and BOM takeoff, representing an internal capacity cost of ₹12,00,000 per month.
By deploying Zero Zeta’s AI-assisted workflow, incoming 2D AutoCAD vessel drawings are ingested and converted into verified parametric 3D CAD with deterministic shell temperature validation (<80°C) and automated BOM generation in minutes.
Before any software rollout, we benchmark the platform on your own historical drawings and documented rules with concrete, auditable acceptance metrics.
Your team provides 1 representative historical drawing (DWG, DXF, or PDF) along with your documented design standards, material grades, and past manual CAD outputs to establish the benchmark baseline.
Zero Zeta configures the extraction engine to your title block formats, calibrates your approved refractory/material thermal tables, and establishes your corporate CAD template constraints.
We run the automated pipeline on the representative drawing in parallel with your historical data: extracting geometry, modeling parametric CAD, verifying thermal boundaries, and generating BOMs.
Joint evaluation against clear acceptance criteria: hours per design, cycle time compression, manual touchpoint rate, BOM consistency, and first-pass accuracy before deciding on production rollout.
