Convergence Geometric
Modeler (CGM)
Developing Next-Generation 3D
Applications Presents Challenges
The steep learning curve required for traditional
parametric modeling
Difficulties in the reuse of existing data models
with the complex constraints of proprietary CAD
systems
Considerable cost and effort to achieve meaningful
prototype results from an initial proof-of-concept

CGM Provides a Platform for Innovation
Tighter application data integration resulting
from geometric data compatibility with Dassault
Systèmes V5 and V6 technologies
Tolerant Modeling designed in from the beginning
to ensure precision for natively built and imported
models
The ability to quickly generate prototype results
with reusable application code to accelerate
development

CGM Enables Efficient Re-Use of Existing
Models
Today, designers may begin projects by leveraging
existing models and data. CGM is architected to take
advantage of this “design-by-redesign” methodology.
CGM provides tight integration with 3D InterOp for
interoperability with leading CAD formats. Native B-rep
interoperability with Dassault Systèmes V5 and V6
preserves full geometric and topological integrity with
existing models.

CGM Delivers Productivity
CGM’s operators offer advanced capabilities to
address the most challenging design and modification
requirements. In addition to offering basic functionality
common to all modelers for operations like tapering
or filleting, CGM provides a smaller set of well
defined, powerful operators which provide highlevel capabilities for addressing complex geometries
and creating results in one step which would require
multiple operations in traditional modelers.

CGM Offers Tools for Earlier Initial Results
CGM incorporates tools and technologies to enable
more efficient 3D modeling. This includes the 3DScript,
a powerful platform for prototyping and collaboration,
which provides a quick, lightweight prototyping
alternative so application developers can quickly
demonstrate their proof-of-concept. They can then
cut-and-paste code into their application to further
accelerate their development.

CGM enables new technical possibilities for
independent software vendors, application providers
and internal development organizations. The CGM 3D
modeling kernel is the core geometry and topology
modeler for Dassault Systèmes’ V5 and V6 and has been
the foundation of V5 products for over ten years, proven
in the most demanding application. CGM is well-suited
for next-generation projects, especially in areas such as
CAM, metrology and point-cloud applications.
