  • The use of extruded surface
  • Trimming surfaces in Solid Edge
  • Thicken surfaces to make solids


  • It is assumed that you are familiar with the basics of Solid Edge Part modeling.

    Drawing the profile - side view

    Start with the x-z plane and sketch the side view profile of the fork as shown in figure.

    Here, the overall dimension of 136 is important and should match the corresponding dimension in the top view profile, as shown in next step.





    Profile - top view

    In the x-y plane, sketch the top view profile of the fork as shown in figure.

    Here, the overall dimension of 136 matches with the dimension in the top 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.





    First Curve


    Select the top view curve as the first curve.

    Click accept     on the ribbon bar.





    Second Curve


    Select the side view curve as the second curve.

    Click accept     on the ribbon bar.





    Cross Curve


    Click Finish on the ribbon bar.

    Soon the cross curve is formed.





    Extruded Surface


    Click the Extruded Surface     tool on the Surfacing toolbar.

    Click Select from Sketch     on the ribbon bar.

    Select the side view profile as shown.

    Click accept     on the ribbon bar.





    Symmetric Extent


    Click Symmetric Extent     on the ribbon bar.

    Specify the extent of the extruded surface as shown.

    Click Finish on the ribbon bar.





    Extruded Surface done

    The extruded surface is formed from the side view profile.

    The top view profile and the cross curve are still unused.





    Trim Surface


    Click Trim Surface     tool on the Surfacing toolbar.

    Select the Extruded surface created in last step as the surface to trim.





    Trimming Profile

    Select the cross curve as the trimming curve as shown in figure.

    Click accept     on the ribbon bar.





    Specify Side

    Specify the side to remove as shown in figure.





    Surface Trim Done

    The surface is trimmed.





    Surface to Solid


    Click the Thicken     tool on the Features toolbar.

    Select the Trimmed surface as shown in figure.





    Surface to Solid Done

    Specify the direction to thicken as shown in figure

    Type a value for the thickness of the fork in the ribbon bar.

    Click Finish on the ribbon bar.

    This makes it a solid fork.





    Take the Cut

    The final step is to take a normal cutout  





    Summary

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

    As the last item shows, don't forget to round the sharp edges before you go for your hakka noodles. Enjoy !
