Multi-Core Processing, Modeling, Blending, Data Import and Repair

India, October 18, 2010 - Siemens PLM Software, a business unit of the
Siemens Industry Automation Division and a leading global provider of product
lifecycle management (PLM) software and services, today announced the latest
release of Parasolid® software, its PLM
industry-leading 3D geometric modeling component. Parasolid Version 23.0 (V23)
delivers a wide variety of enhancements which reflect Siemens PLM Software’s
continuing emphasis on increasing productivity by supporting complex processes
throughout the entire product development process.

“The impressive success and widespread adoption of Parasolid
throughout the world is a testament not only to its ability to deliver
world-class functionality for product design, analysis and manufacturing, but also its focus on making
application developers more efficient so they can concentrate their efforts on
adding value to their own software solutions,” said Joan Hirsch, vice president
of Product Design Solutions, Siemens PLM Software. “With Parasolid V23, we have
maintained that balanced approach with enhancements that address the needs of
both developer and end user.”

“Thread-Safe” Parasolid

Parasolid has extended its support for multi-core processor
hardware to enable applications based on Parasolid to take full advantage of
their significant performance advantage over single-core processors. Parasolid
V23 is now fully thread-safe, enabling applications to have several threads
running on different processors, with each calling any Parasolid function
simultaneously. This is possible due
to optimized thread, session, and
memory management as well as error reporting capabilities in Parasolid V23 that
free the application developer from the need to coordinate the multi-thread
function calls. As a result, applications based on Parasolid can benefit from
multi-core processing speed with less time spent in application development.

Face Deformation

A new face deformation operation enables highly
sophisticated shape changes to digital models based on either design
requirements or simulations of shape changes that occur due to real-world
situations such as deflection under load or distortion during temperature
cycles. Any set of faces in a model can be selected for deformation as defined
by a mathematical function provided by the application.  This
new capability is particularly powerful because the deformation preserves and
adjusts existing features, such as offsets and blends, and the deformation may
also be applied simultaneously with other model edits.


In response to the needs of product designers who need to
create and modify complex geometry with maximum productivity and flexibility,
Parasolid V23 introduces more sophisticated blending techniques and controls
that extend the software’s already impressive range of blending capabilities
into the domain of complex modeling.

·         New options are now available to provide more
refined control over the shape of chord width blends – blends that create a
uniform, aesthetically pleasing shape and are particularly useful when working
with high-quality curved surfaces. Variable chord width face blends provide new
methods of defining the chord width and ratio of face blends as being constant
or variable according to application-provided functions. Chord width face
blends, both constant and variable, are also enhanced with the ability to now
have disc cross sections in addition to existing rolling ball cross sections.

·         Edge Blends can now be defined to be trimmed
(i.e. terminated) at a specific edge or face, providing more immediate,
localized and robust control of complex blend interactions.

Data import and repair

As the geometric modeling component – or kernel – of choice
in many of the world’s leading CAD, CAM and CAE applications, Parasolid is
often required to work with imported data from other systems that require
various levels of geometry and topology repair. Parasolid V23 includes several
new functions to enhance data import and repair.

·         A new function enables Parasolid to analyze
the topological structure of a model and repair ambiguities, thereby producing
data that often meets the rigorous requirements of a fully consistent
boundary-representation (b-rep) model, while maintaining the intent of the
original data. For example, Parasolid can now detect and repair topological
clashes between shells where two faces from different shells share a common
edge, greatly reducing model repair time.

·         Parasolid can now automatically detect and
repair surfaces that are ill-defined and unstable because they contain
“degeneracies” which may go unnoticed in less accurate and less rigorous

·         A new option to the model checking function in
Parasolid improves the productivity in working with imported data by
automatically requesting more detailed reporting including new fault codes

Neutral Sheet Modeling

Parasolid V23 includes further enhancements to the rapid
development of neutral sheet modeling technology, targeted at the
computer-aided engineering analysis (CAE) market. Performing these operations
at the kernel modeler level has significant advantages of performance, model
consistency and functional robustness over implementing them at the application
level. New Parasolid functions are provided for detecting and optionally repairing
overlapping neutral faces – even those that may occur in apparently simple
configurations – in a fraction of the time it would take to perform this task
manually. Neutral sheet faces may now also be shared between more than one pair
of model faces for improved performance and reduced model size.


New controls have been added to the sweeping operation and
restrictions have been removed to make it quicker and easier to achieve the
desired shape in a single operation. A sweep can now be locked to face normals
where the sweep path lies on a set of faces. Continuity restrictions on sweep
paths have been lifted to allow visibly smooth paths where guides, multiple
profiles, scale, or twist laws are also supplied. Sweeps can now also be
performed between multiple profiles, each having multiple loops to create
