With Creo Parametric Flexible Modeling Extension (FMX), you can easily modify geometry by simply selecting and dragging. But what happens to neighboring surfaces? Especially those with a tangential connection to the surface you’re modifying?
Among the enhancements in Creo 3.0, you can now maintain those tangent connections. The following video demonstrates:
To try it yourself, follow these steps:
This enables tangency control, which allows you to maintain the existing tangency to surfaces directly adjacent to the geometry that is being modified. This means that the neighboring surfaces will be adjusted along with the primary surface to maintain the tangential connection.
The system automatically applies some default conditions to the neighboring geometry so you maintain tangency. Need more control?
To apply user-defined conditions, follow these steps:
Note. You can fix surfaces, edges, or axes, specify what tangencies should be maintained or lost, and maintain constant radii.
User-defined conditions can also be created by right clicking the applicable reference, and selecting from the Right Mouse Button menu. For example, you can right click on a cylindrical surface and select Fixed with Tangency to add a condition.
