Definition
CAD integration means connecting your CAD software with other business and engineering systems, so that part data, BOMs, documents and status information move between them automatically, without re-typing or file shuffling.
Which systems connect to CAD?
| System | What is exchanged |
|---|---|
| ERP (SAP, Oracle, Dynamics, Odoo, Tally) | Item masters, BOMs, costs, stock, routings |
| PDM / PLM (Vault, SOLIDWORKS PDM, Windchill, Teamcenter, ENOVIA) | Files, versions, revisions, lifecycle status, changes |
| MES | Released drawings, work instructions, NC programs |
| CRM | Customer requirements, configurations, quotes |
| CAM / CNC | Geometry, features, toolpaths, G-code |
| CAE (FEA, CFD) | Geometry, loads, results, design changes |
| Excel and databases | Parameters, catalogues, reports |
Why it matters
- No double entry: data is created once in CAD and reused everywhere.
- Fewer errors: no typing mistakes between systems.
- Speed: purchasing and production start sooner after release.
- Visibility: everyone sees the current revision and status.
- Traceability: changes are recorded end to end.
Integration patterns
File-based exchange
CAD exports CSV, XML or Excel files that the other system imports. Simple and low cost; good as a first step.
API-based integration
Software talks directly to each system's API (for example ERP web services), in real time or on events. More robust and automatic.
Middleware / integration platform
A central service maps and routes data between several systems, handling queues, retries and logs. Best for complex landscapes.

- Map current data flows and pain points.
- Decide the "system of record" for each data item.
- Standardise CAD properties and part numbering.
- Define mappings and triggers (for example "on release").
- Start with one high-value flow, such as BOM to ERP.
- Add monitoring, error handling and logs.
Integration is 20% technology and 80% agreeing on data ownership and standards.
