Siemens PLM Software introduces Synchronous Technology, a history-free, feature-based modeling technology that is said to provide the flexibility and freedom to make design changes at will without losing the knowledge gained with constraint- and dimension-driven CAD systems.

Editing designs can be difficult with conventional history-based systems. When a change is entered, such systems must re-execute all subsequent commands in the history tree to rebuild the complete model. This process can be time-consuming, especially for large, complex models. In addition, design edits can cause unwanted ripple effects in features located later in the history tree because of complicated constraint relationships among solid model features.

With the modeling technology, however, designers no longer have to carefully evaluate constraint relationships or worry about downstream implications in order to understand how to approach a model edit, the company says. The system recognizes a model’s geometry and localizes dependent relationships to only the features to which they apply. In short, users can construct new geometry and edit models without the need for a full history replay.

The company will implement the technology in the next versions of its Solid Edge and NX software. According to the company, the technology will reduce development cycles; make coping with both planned and unplanned product change easier; allow designers to work on product models they did not originally author; increase potential to reuse designs without remodeling; and more.
