If you change the dimension of the original sketch, the entire chain of events updates. The hole moves, the fillet adjusts, and the shell thickness stays constant. It offers "Design Intent."
The core philosophy is simple:
With Solid Edge Synchronous, imported geometry is a first-class citizen. Because Synchronous technology doesn't rely on a history tree, you can open an imported model, select a face, move it, cut it, or resize it as if you had created it yourself. solid edge synchronous
The "Parent-Child" relationship. If you try to delete a feature that other features rely on, the model breaks. Editing a complex model created by someone else is often an exercise in detective work—deciphering their history tree to figure out how to make a simple change without crashing the geometry. The Direct Modeling Approach Direct modeling bypassed the recipe. It treated geometry as... well, geometry. You grabbed a face and moved it. You selected a hole and deleted it. There was no history tree to manage. If you change the dimension of the original
Lack of intelligence. If you moved a wall in a direct model, the neighboring fillets didn’t always know they should update. It was difficult to drive design changes parametrically (e.g., "make this width always half of that length"). 2. What is Solid Edge Synchronous Technology? Solid Edge Synchronous Technology is a hybrid modeling approach that merges the speed and flexibility of direct modeling with the control and parametric intelligence of history-based modeling. It was introduced in 2008 and remains one of the most unique differentiators for Solid Edge in the mid-range CAD market. Because Synchronous technology doesn't rely on a history
