May 5, 2011 - Siemens PLM Software released Parasolid Version 23.1. Enhancements include:
CAE Support
Targeting the significant Parasolid computer-aided engineering (CAE) user community, Parasolid V23.1 includes new enhancements to its robust sheet modeling technology.
- Neutral sheets
- Wire bodies and sheet bodies can now be united together using Boolean operations facilitating more flexible workflows.
- Enhancements to the faceting capability include additional mapping of facet topology to the model topology of the part from which the facets were created, simplifying the process of establishing the relationship between the facets and the model when performing analysis.
may now be created from multiple faces in a single operation with control over how sheets are extended to create a valid solution and how holes in resulting neutral sheets are filled.
Interoperability
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 V23.1 includes several new functions in this area.
- A new function helps create the topology of a body when importing boundary representation data into Parasolid.
- A new function uses different methods, under the control of the calling-application, to streamline the attachment of geometry to edges during the data import process.
- Two new functions are added to find and repair degeneracies in surface data imported from other systems.
- Improvements in sheet body thickening automatically detect and repair degeneracies in the input bodies.
This provides more diagnostic information to the calling-application that can be used to fine-tune the import process.
This helps eliminate the problems caused by degeneracies, such as self-intersections, that can disrupt modeling operations performed at the higher precision used by Parasolid.
Further improvements automatically repair self-intersections that may arise when thickening a sheet with tightly-curved areas by more than its radius of curvature.
Application Support
Several enhancements have also been made to improve the productivity of developers integrating Parasolid into a new or existing application, including the two enhancements highlighted below.
- Imprinting - A new API is provided with a revised options structure and tracking information to improve application management of imprinted entities.
- Groups - A new system attribute is provided to specify the behavior of empty groups when the owning parts are split or merged to provide applications with greater flexibility when managing groups.
Modeling Enhancements and Availability
Parasolid V23.1 also includes a large number of additional enhancements as well as significant extensions to the breadth and depth of functionality in the areas of blending, local operations and surfacing. Parasolid V23.1 is available immediately.
