DESCRIPTION:
This is very impotent option using in pro engineer. Swept Blends relation between Sweep and Blend. This can be creating different profiles of sketch.
A swept blend can have two trajectories: an Origin Trajectory (required) and a Secondary Trajectory (optional). Each Swept Blend feature must have at least two sections and sections may be added between these two sections. To define a trajectory of the swept blend, you can select a sketched curve, a chain of datum curves, or edges. Only one trajectory is active at a time.
You sketch the sections to be blended at specified segment vertices or datum points on the Origin Trajectory. To orient a section, you specify the direction of the sketch plane (the z-axis) and the horizontal/vertical direction to that plane (the x-or y-axis). Use the Selected Sections option to select sections that were sketched before you enter the swept blend tool. Use the Sketched Sections option to sketch sections at points along the selected Origin Trajectory.
