EMUG Tech delivers CAD customisation and automation across six areas: NX Open API automation (C++ applications and Python scripts for Siemens NX); Solid Edge .NET API automation for drawing, BOM, and file management; Creo Toolkit C/C++ automation for PTC Creo Parametric workflows; CATIA V5 CAA workbench development and 3DEXPERIENCE VSTA scripting; multi-CAD and neutral format conversion automation (STEP, JT, IGES, Parasolid); and CAD-to-PLM integration connecting CAD workflows to Teamcenter, Windchill, and 3DEXPERIENCE. All programmes follow the EMUG CARVE Framework — Capture, Architect, Realise, Validate, Enable.

EMUG CARVE is the five-phase CAD automation delivery methodology: Capture — CAD workflow observation, effort quantification, and automation feasibility assessment; Architect — tool design, UI wireframes, PLM integration specification, and development architecture; Realise — CAD API development, unit testing, and documentation; Validate — integration testing with production model data and user acceptance testing; Enable — production deployment, user training, and 30-day adoption monitoring. CARVE ensures CAD automation tools are built from observed real workflows rather than assumed requirements, tested against complex production models before go-live, and deployed with training that achieves above 80 percent adoption within 30 days.

NX Open is the Siemens NX application programming interface — available in C++, Python, and Java — that allows developers to control and automate NX operations programmatically. NX Open can automate: parametric model creation from external data (Excel, PLM attributes, or database inputs); drawing sheet creation, view placement, and annotation from 3D model data; BOM extraction and attribute population for PLM import; model quality validation against corporate standards using Check-Mate rules; assembly configuration management and component positioning; mass property extraction and reporting; and CAD-to-neutral format export (STEP, JT, IGES, STL) at model checkin. EMUG Tech delivers NX Open automation from journal-level scripting through to compiled NX Open application development with NX dialog-based user interfaces.

Creo Toolkit is PTC’s C/C++ programming interface for deep integration with Creo Parametric — providing access to model geometry, parameters, features, assemblies, drawings, and Creo session management that the higher-level Creo Parametric API does not expose. Creo Toolkit automation covers: family table management and generation from design specifications; automated drawing creation from 3D model parameters and views; mass property extraction and reporting; model validation and quality checking tools; assembly automation for configurable and modular product families; and integration with Teamcenter or Windchill for automated save, attribute transfer, and BOM extraction. EMUG Tech also delivers Creo automation at the Pro/PROGRAM level for knowledge-driven design and at the VB-API level for simpler workflow automation requirements.

CATIA CAA (Component Application Architecture) is Dassault’s C++ framework for developing native CATIA V5 workbenches, add-ins, and commands — providing the deepest level of CATIA integration available, with access to all CATIA geometry, feature trees, assembly constraints, and product data structures. CAA is needed when: automation requirements involve complex surface geometry, multi-body solid operations, or assembly constraint creation that CATScript macro automation cannot handle; a custom CATIA toolbar with persistent commands is required; integration with CATIA PLM data structures (CATIA V5 with ENOVIA) is needed; or the automation must handle Catia V5 Knowledgeware parameters and design tables. For simpler CATIA automation, EMUG Tech delivers CATScript macros and 3DEXPERIENCE VSTA scripts before recommending the CAA investment.

EMUG Tech connects CAD automation tools to PLM systems using the PLM’s documented REST API or SDK: Teamcenter integration uses the Teamcenter Services REST API and Active Workspace API for item creation, attribute update, file management, and workflow triggering; Windchill integration uses the Windchill REST Services (WNC) for part, document, and change management operations; 3DEXPERIENCE integration uses the 3DEXPERIENCE REST and widget APIs. In the CAD tool, the PLM integration layer reads PLM item attributes to drive automation logic (tool reads material, revision, and tolerancing standard from the Teamcenter item to configure the drawing automatically) and saves automation outputs (drawings, neutral formats, quality reports) directly to the PLM item without engineer manual upload steps.

A focused single-function CAD automation tool — for example, an NX drawing automation tool creating a complete 2D drawing from a 3D model with standard views, title block population from PLM attributes, and BOM table — typically takes 6 to 12 weeks from Capture to Enable deployment. A multi-function automation programme covering 4 to 6 tool modules — drawing automation, BOM extraction, model quality check, and PLM integration — typically takes 3 to 6 months. The timeline varies by CAD API complexity: CATIA CAA development takes longer than NX Python scripting for the same functional scope. The Capture phase (2 to 3 weeks) is fixed regardless of tool complexity, as workflow observation cannot be shortened without missing edge cases that cause production failures.
