History

1969:
UNIAPT was released by a software company then called United Computing, UNIAPT was one of the world's first end-user CAM products.

1973:
The company purchased the Automated Drafting and Machining (ADAM) software code from MGS in 1973. The code became a foundation for a product called UNI-GRAPHICS, later sold commercially as Unigraphics in 1975.

1976 McDonnell Douglas

1992:
Over 21,000 seats of Unigraphics are being used worldwide.

1996:
Unigraphics V11.0 is released. Added Industrial Design and Modeling enhancements including Bridge Surface, Curvature Analysis for Curve and Surfaces, Face Blends, Variable Offset Surface, etc. In the area of Assembly Modeling the new capabilities included Component Filters, Faceted Representations, Clearance Analysis between multiple Components, etc. Also this release included a fully integrated Spreadsheet linked to Feature-Based Modeling.

2002
First release of the new "Next Generation" version of Unigraphics and I-deas, called NX. This will eventually bring the functionality and capabilities of both Unigraphics and I-DEAS together into a single consolidated product.
