Create a Cut Use Quilt [select the surface we just created] [select the right side] and see the result. As you can see, the profile has been swept normal to the origin trajectory. (Note: Origin trajectories must be straight, or curve that are tangential. This restriction doesn39。t apply to the other trajectories. The origin trajectory determines the overall length of the feature.) Example 2 Rounded Corner I will use the method I described above to create a rounded corner surface cut on the part. Create an Insert Surface Extrude Capped Ends as shown below: Create three curves in order to define the VarSecSweep option as shown: The system orients you to the sketcher in order to sketch the profile. Create a spline between the two points, then again create two centerlines and then make the spline tangent to them (see below). Click Done and then Insert Surface Operations Merge [select the cube first and then the surface you have just created]. Click Ok and you have a rounded corner tangential to all sides. Example 3 The Effects of Trajectory Lengths I will use the above option of VarSecSweep (NormToOriginTrajectory) to create a more advanced scheme, after which we will make some changes to better understand this great functionallity of Pro/E. This is the final surface that will be created: First, create four 2D curves as shown below : We will use the left curve to define the origin trajectory and the three curves to the right to define first, second, and third trajectories. After we select the trajectories the system enters into sketcher mode to define the section profile. Create a spline as shown below... ...then create three centerlines and make the section tangent to the centerlines... ...and done. Now let’s make some changes to the curves. First I will decrease the size of the origin trajectory. Regenerate, and the result: As we can see, the system builds the surface along the origin trajectory and stops at the end of it. Now I will make the size of origin trajectory longer than the other three curves: Regenerate, and the result: As we can see, the system builds the surface until it finds the first end of the other three curves. In our example, the surface stops at the end of the middle curve (of the three). As we can see, the system builds the surface always normal to the origin trajectory. Let39。s continue with the a
