NexyFab
What do you want to design?
Describe what you want to design in plain language, or upload a drawing/sketch. From mechanical to civil, architecture, landscape and interior.
Deterministic calc engine · engineering corpus · every result cites its code clause
Upload a drawing/sketch and we read the orthographic views into 3D (supported: plate · bracket · flange · pipe · rect tube · bar · gusset · base plate, etc.)
AI replies are non-statutory references. Final review and sign-off remain a licensed engineer’s responsibility.

Nexyfab · Why.
Different Standard of Connection
Not just simple matching, but matching based on actual feasibility and suitability.
Data-Based Filtering
Keyword interpretation, similar references, industry/equipment/process suitability are all reflected.
Project Info Confidentiality Principle
Actual company names are not shown to customers, and are managed only for internal verification.
Fast to Decision-Making
Not a "list of possible companies", but compressed "suitable candidates to review first".

Project InquiryNexyFab · Capabilities.
All-in-One Tools for Engineers
Design → quote → Korea-partner fulfillment in one chain. OpenSCAD-friendly · collaborative · no install.
Parametric 3D CAD
16 shapes, sketch-to-extrude, fillets, chamfers, patterns, and professional features.
Topology Optimization
SIMP algorithm generates optimal structures, reducing material by up to 40% while maintaining strength.
Nexyfab · Use Cases.
Strong in these projects
We provide examples based only on
project types, without disclosing actual company/customer names.
Automation Equipment
We select automation equipment partners by reflecting
process conditions/layout/safety requirements.
Special Purpose Equipment
Since "manufacturing feasibility" is key for special equipment,
we prioritize similar references.
R&D Prototype
Based on similar references and technical scope, we only narrow down manufacturing partners with high actual implementation possibility.
Plant/Equipment
For plant equipment, candidates are quickly connected
based on similarity, safety, and delivery time.
Company/Project names are not disclosed externally.
Required information is requested according to the progress stage,
and shared only with suitable partners after internal review.

Structural checks, as easy as a calculator
No sign-up — this calls the real verification engine. Results cite the governing KDS clauses.
VERIFIED · AI-NATIVE
We brag about verification, not customers
A deterministic engine does the math — never an LLM — and every result cites its code clause.

Start FreeFrequently asked questions
Can I use the results as sealed structural calculations?
No. NexyFab outputs are non-statutory engineering references. Sealed calculations for permits remain the domain of licensed engineers, and every response states this limit.
Which design codes are supported?
10 current KDS codes (steel, retaining walls, and more), cross-checked against the official text, plus AISC 360 and AASHTO LRFD. Every result cites its governing clause.
Does an AI do the math? Can I trust it?
No — a deterministic engine performs all calculations; AI only assists with input setup and interpretation. The engine passes 37 golden-bench cases and reproduces 6 published worked examples.
Can I integrate it into my service or AI?
Yes, via REST API (API key) or the MCP server. The API exposes calculator lists and input schemas, so you can auto-generate function-calling tool specs.
