• Wire bodies and sheet bodies can now be united together in Boolean operations.
• Thickening of sheet bodies has been improved to automatically detect and repair degeneracies in the input bodies, together with further improvements to automatic repair of self-intersections that may arise when thickening a sheet with tightly-curved areas by more than its radius of curvature in certain areas.

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 to create the topology of a body provides extended diagnostics that can be used to fine-tune import of boundary representation data into Parasolid
• A new function is provided to streamline the attachment of edge geometry using different methods, under the control of the calling-application.
• Two new functions are added to find and repair degeneracies in imported surface data to facilitate optimal behavior in downstream modeling operations  performed at the higher precision used by Parasolid.

Application Support

Numerous enhancements have been made to improve the productivity of developers integrating Parasolid into a new or existing application. These include:

• Imprinting - a new API is provided with a revised options structure and tracking information.
• Facetting – additional mapping of facet topology to the  model  topology of the part from which the facets were created.

Modeling Enhancements

Parasolid v23.1 also includes a large number of small enhancements together with extended case coverage and robustness in the areas of blending, local operations and surfacing.
