Siemens PLM Software Delivers Parasolid V23 to Increase Productivity in Application Development

Supplier News

Siemens PLM Software  introduces the latest release of Parasolid software, the PLM industry-leading 3D geometric modelling component designed for application development.  

Siemens PLM Software is a business unit of the Siemens Industry Automation Division and a leading global provider of product lifecycle management (PLM) software and services.  

Parasolid Version 23.0 (V23) delivers a wide variety of enhancements that reflect Siemens PLM Software’s continuing emphasis on increasing productivity by supporting complex processes throughout the entire product development process.  

Joan Hirsch, Vice President of Product Design Solutions, Siemens PLM Software says that Parasolid’s success is attributable to its ability to deliver world-class functionality for product design, analysis and manufacturing while simultaneously increasing the efficiency of application developers so they can concentrate their efforts on adding value to their own software solutions.  

She adds that Parasolid V23 offers enhancements that address the needs of developers and end users.  

‘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.    

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 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.


Parasolid V23 introduces sophisticated blending techniques and controls that extend the software’s already impressive range of blending capabilities into the domain of complex modelling.    

Blending capabilities developed in response to the needs of product designers include:

  • Options are available to provide more refined control over the shape of variable and constant chord width blends
  • Edge blends can be defined to be trimmed at a specific edge or face, providing more immediate, localised and robust control of complex blend interactions

Data import and repair  

Parasolid is the geometric modelling component of choice in several leading CAD, CAM and CAE applications, and is often required to work with data imported from other systems that requires various levels of geometry and topology repair.    

Parasolid V23 includes several new functions to enhance data import and repair: 

  • Analyse the topological structure of a model and repair ambiguities to produce data that often meets the rigorous requirements of a fully consistent boundary-representation (b-rep) model, while maintaining the intent of the original data
  • Automatically detect and repair surfaces that are ill-defined and unstable because they contain ‘degeneracies’
  • New option to the model checking function improves productivity in working with imported data by automatically requesting more detailed reporting including new fault codes

Neutral Sheet Modelling  

Parasolid V23 includes further enhancements to the rapid development of neutral sheet modelling technology, targeted at the computer-aided engineering analysis (CAE) market.    

Performing these operations at the kernel modeller 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 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 disjoint bodies.
