Creo 9.0 introduces two new features: Divide Surface and Unify Surfaces.

The Divide Surface feature, a replacement for Surface Region found exclusively in Creo Simulate, allows users to split a portion of a surface into a new, adjoining surface. This capability, unavailable in earlier Creo versions, enhances productivity for various scenarios where surface areas are needed as referenceable objects in the model geometry. The Divide Surface feature supports both Sketch projection-based and Chain-based creation methods.

Supported key use cases for Divide Surface include:

•In the Model-Based Definition where Product Manufacturing Information (PMI) can use divided surfaces as a semantic reference that supports aspects such as semantic query, control characteristics designation, and more.

•Simulation and Generative Design leveraging divided surfaces for the definition of loads and constraints or meshes.

•Rendering aesthetics such as appearance, surface finish, texture.

•Data exchange.

•Basic workflows for geometry creation and modification, such as engravings.

The second feature, Unify Surfaces, serves to consolidate surfaces created through the Divide Surface feature or those generated during model imports. With Unify Surfaces, users can merge selected surfaces into a target surface while preserving its identification and properties, including appearance. The option to Update Surface References allows for forwarding surface references from children features to the target surface.

This enhancement provides the ability to geometrically reverse the division of surfaces, addressing a limitation that existed in previous versions.
