Surface Modeling - Mountain Bike Handlebar

In this tutorial you learn :

 

  • How to model a Mountain Bike Handlebar using surfacing commands in Solid Edge
  • How to use the cross-curve command
  • The use of swept surface
  • How to thicken surfaces to make solids
    It is assumed that you are familiar with the basics of Solid Edge Part modeling.

    Index of all Solid Edge surfacing tutorials on this blog is here.

    Create Two Planes


    Start with creating two planes parallel to the y-z plane
    The distance between the planes is 50 (see figure)

     


    t2101

    Drawing the profile - front view

    In the x-z plane, sketch the front view profile of the handlebar as shown in figure.
    Keep the profile between the two planes created in the earlier step.

     

    t2102

    Profile - top view

    In the x-y plane, sketch the top view profile of the handlebar as shown in figure.
    Here, the overall dimension of 100 matches with the dimension in the front view profile, as shown in earlier step.
    Also make sure sure that the two profiles are vertically aligned.

    Cross Curve


    Select the Cross Curve command from the Surfacing toolbar as shown.

     

    t0103

    First Curve


    Select the front view curve as the first curve.
    Click accept  
    accept   on the ribbon bar.

     

    t2104

    Second Curve


    Select the top view curve as the second curve.
    Click accept  
    accept[4]   on the ribbon bar.

     

    t2105

    Cross Curve


    Click Finish on the ribbon bar.
    Soon the cross curve is formed.
    The cross curve is neither in the top plane nor in the front plane.
    It travels in 3D space, giving us the desired path to create the handlebar.

     



    t2106

    Normal Plane


    Create a plane normal to the new cross curve at one of its end.
    Use the Plane Normal to Curve command from the Features toolbar.

    Plane Created


    The new plane appears smaller in size than parallel created planes.
    Your figure should now look as shown.

     

    t2107

    Sketch the profile


    Create a sketch (a circle) on the new plane and at the end of the cross curve.
    See figure.

     

    t2108

    Extruded Surface


    Click the Swept Surface   swepsurf   tool on the Surfacing toolbar.
    Complete the extrusion of the circle along the cross curve

     


    t2109

    Close Ends


    In the Swept Surface, click the Close Ends option on the ribbon bar.
    This ensures that the ends of the protrusion are capped or closed.

     





    t2111

    Surface to Solid


    Click the Thicken   thicken   tool on the Features toolbar.


    The thicken command is on the Thin Wall fly out.


    Select the swept surface and thicken it by 2.


    Finally, round the end faces of the solid handlebar. (see figure)

    Summary


    The figure on right shows the summary and sequence of all commands.
