Synchronous technology

Siemens PLM Software believes that its new synchronous technology represents the next dramatic change to the CAD world and sets a milestone in the history of 3D CAD design much like parametric modelling did in the 1980s.

Dr Ken Versprille, partner and PLM Research Director at Collaborative Product Development Associates, LLC, defines synchronous technology as ̶0;a history-free, feature-based modelling system that combines the best of dimension- and constraint-driven techniques for full control and repeatability, with the flexibility of direct modelling.̶1;

He explains: ̶0;Synchronous technology breaks through the architectural barrier inherent in a history-based design system that cannot fully determine dependency implications and must therefore rely on a full re-execution of the sequential modelling history.̶1;

The new technology builds on recent CAD advances to ̶0;mine̶1; intelligence from generic solid models. The performance improvements it enables will result in ̶0;dramatic development process gains,̶1; says Versprille.

He believes product manufacturing companies will see decreased time-to-revenue, increased ability to cope with unexpected product changes, dramatic supply chain improvement, increased ability to explore design alternatives rapidly, more design reuse without remodelling and an overall ability to react faster to market changes later in the development cycle.

The technology acts as a design application layer that sits between the operational logic of design create/edit commands in the CAD application and the basic geometry of a geometry kernel. So it draws information from both the current state of the geometric model and any constraints imposed by the user.

̶0;As product development companies leverage the power and performance of synchronous technology, the competitive advantages they realise will fuel its adoption,̶1; he predicts.

̶0;There will be no going back to flooding a product model with user-defined geometric constraints. Synchronous technology will automatically discover geometric conditions apparent in the model and preserve them during edits. The new intelligence of CAD modelling will virtually blast from their desktop screens.̶1;
