CATIA FMP


Functional Molded Parts is a new generation of non-history based 3D modeling delivering unmatched productivity and flexibility. Functional modeling frees the user from the notion of history in that the order of creation of the features have no impact on the design itself.


Specific functional characteristics

CATIA's Functional Molded Part (FMP) is a part of MCE module and enables flexible and productive 3D modeling package dedicated to the design of molded and plastic parts. The application provides direct access to a collection of intuitive and powerful functional features that are useful for designing molded parts.  These are core and cavity design functional features that are used often throughout the design process, such as Extrude, Revolve, Cut, Thicken surface, Rib, Boss, Cutout, Rest, Pocket, Grill, Reinforcement, Shell and others.

Functional Modeling for Flexibility and Productivity

FMP gives the mold part designer flexibility and productivity increases thanks to its functional modeling approach.  These functional features differ from most other feature-based parametric CAD systems (including CATIA Part Design) in that each FMP feature performs a complex modeling task in one operation that would usually require several dedicated features.  This all-in-one concept saves considerable time when elaborating on a complex form.

A cutout is one of several shape modifiers used within plastic part design:

Estimated 20% Savings (in time and complexity): 

  • The cutout is added after the wall thickness is defined, so there is no need to re-order 
  • Changes to the shape of the feature are easily executed and automatically updated
  • The Cutout feature modifies the shelled body while keeping the wall intact
  • Cutout shape becomes a protected area, preventing any other geometry from being constructed in that area

New way of thinking the design due to its unique semantic features which enables designers to focus on WHAT they want to model and not HOW to model it

Non-history based 3D modeling

Users have the flexibility to focus on their design intent and not on the order in which they create design elements.

The built-in associative intelligence of functional bodies, volumes, and features ensures that design changes can be made quickly and safely at any time during the product's life cycle.

This approach greatly facilitates concurrent engineering because Designer B can work on a functional part without any consideration of the way it was previously modeled by Designer A.

 Process Coverage through CATIA V5 Integration

Total integration with the CATIA V5 portfolio of applications ensures end-to-end process coverage. This level of integration provides molded part designers with a comprehensive solution to cover the design to manufacturing plastic part creation process, from preliminary to detailed design. It can be used with such powerful products as its prerequisite CATIA - Part Design 2 product for 3D design in assembly contexts and with CATIA - Generative Shape Design for creating specification-driven shapes, such as complex sweeps and fillets. Drafting tools, such as CATIA - Interactive Drafting and CATIA - Generative Drafting, are highly recommended to extend the product's drawing production capabilities.

Accelerates the adoption of CATIA design practices in the powertrain industry with functional modeling and traditional 3D design

  • Functional modeling encapsulates the intended feature behavior

  • Minimizes the number of features

  • Focus on WHAT you want to model and NOT HOW to model it

  • Functional behavior of the features is always preserved in case of modification

  • Cornerstone for instant collaborative design
