    A clearer view

    Although the two BlueSurfs begin with different curves ( an arc and a converted curve), they both have a comon curve - the smaller arc on the far side.

    See figure.

    The red arrow points to the common arc on the far side.

    The yellow arrow points to the larger arc and the green arrow points to the arc-converted-to-curve.





    Profile - top view

    In the x-y plane, sketch two arcs as shown in figure.

    The two arcs do not touch each other nor they are parallel.





    Project Curve - Curve Step


    Select the Project Curve     tool from the Surfacing toolbar.

    Select the left-side arc as the curve to project.

    Click accept     on the ribbon bar.





    Project Curve - Body Step

    Select the top-side Bluesurf as the surface to project on and indicate the arrow towards the Bluesurf in the next step.

    Similarly, project the right-side arc on the lower-side BlueSurf.





    Project Curve - Ready

    Now you have two BlueSurfs with an arc projected on each of them.

    See figure.





    Trim Surface - Surface Step


    Select the Trim Surface     tool from the Surfacing toolbar.

    Select the top-side Bluesurf as the surface to trim.






    Trim Surface - Curve Step

    Select the curve projected onto this BlueSurf as the trimming curve.

    Click accept     on the ribbon bar.





    Trim Surface - Side Step

    Indicate the arrow pointing to the right side as the part to trim off.

    See figure.





    Surface Trimmed

    The Bluesurf is trimmed as shown in figure.





    Once More

    Similarly, trim the lower-side BlueSurf using the curve projected onto it.

    The two BlueSurfs look like as shown in figure.





    Derived Curve

    Click the Derived Curve     tool on the Surfacing toolbar.

    Select the Select Curves     button on the ribbon bar.

    Seelct the two arcs as shown in figure.

    Click Finish on the ribbon bar.

    A derived curve is created.





    Split Curve - Begin

    Click the Split Curve tool on the Surfacing toolbar.






    Split Curve - Select Curve Step

    Select the derived curve as shown.





    Split Curve - Who Will Split

    Select Keypoint from the pullbown list in the ribbon bar.





    Split Curve - Pick the Keypoints

    As shown in figure, select the two keypoints at the intersection of the derived curve and the projected curves.





    Split Curve - Once More

    Similarly, split the other derived curve at two keypoints as shown in figure with the two yellow arrows.





    Disply Required Curves

    Adjust your dislay such that the projected curves and the split curves are only entities visible.

    See figure.





    Bounded Surface - Begin

    Click the Boundeded Surface     tool on the Surfacing toolbar.

    Select the four curves as shown in figure.






    Bounded Surface - Finish

    On the ribbon bar, click the accept     Preview and Finish buttons in that order.

    A Bounded Surface is created as shown in figure.





    Stitch the Surfaces

    Display all the surfaces again.

    Click the Stiched Surface     tool on the Surfacing toolbar.

    Select the two BlueSurfs and the Bounded surface.

    click the accept     and Finish buttons on the ribbon bar.

    The three surfaces are stitched together to form a single surface.





    Surface to Solid


    Click the Thicken     tool on the Features toolbar.

    The Thicken tool is in the same flyout as the Thin Wall and Thin Region tools.

    Select the stitched surface to thicken.

    Use a small value of 1 mm to thicken in any direction.





    The Hurled Surface is Ready

    This way Hurled surfaces can easily be created in Solid Edge.

    Hurled Surfaces find many uses in Industrial and Product design.

    Imagine this surface to be on one side of a talcom powder plastic bottle. The hurl (step) acts as a smooth grip to hold the bottle and at the same time providing aesthetic looks to the bottle i.e. there are no sharp edges.

    Other examples are four-wheeler bonnet, etc.

    As an example, this bottle has hurled surfaces in atleast 3 places. Can you identify them.
