Bluesurf - Modeling a Mouse

In this tutorial you learn :


  • How to model a mouse using the BlueSurf feature in Solid Edge
  • How to use the BlueDot
  • How to replace surfaces
  • Project curves onto surfaces
  • Derive curves in Solid Edge
    It is assumed that you are familiar with the basics of Solid Edge Part modeling.
  • Full index of Solid Edge surfacing tutorials on this blog is here.


    Visualize First

    From front, the mouse would look something as shown in figure.



    Sketch It

    So, in the x-z plane, sketch a spline as shown.



    Visualize Again

    From left, its like this.



    Sketch the Other View

    In the y-z plane, sketch a spline as shown.



    Prepare for BlueDot

    Click the BlueDot   bluedot   tool from the Surfacing toolbar.

    Click the two splines one after the other.



    Tie the Splines

    Click Finish on the ribbon bar.

    The two splines get tied with a bluedot at their intersection.



    Create the BlueSurf

    Click the BlueSurf   bluesurf   tool from the Surfacing toolbar.

    Select one of the splines.

    Click accept   accept   on the ribbon bar.
    Then select the other spline.
    Click Finish on the ribbon bar.
    A bluesurf is created as shown in figure.



    Create the Body Profile

    The bluesurf created in last step is the top surface of the mouse that would fit into your palm.
    Hide the bluesurf for now.

    To create the body of the mouse, draw a profile in the x-y plane as shown.



    Create the Body

    Extrude the profile as shown to an arbitrary height.
    This can be changed later to suit.



    Display the Surface

    Display the previously hidden bluesurf.



    Select Face to Replace

    Click the Replace face   replface   tool from the Surfacing toolbar.

    Select the top face of the protrusion.
    Click accept  
    accept[4]   on the ribbon bar.



    The Replacing Face

    Then select the bluesurf as the replacing face.
    Click Finish on the ribbon bar.



    Face is Replaced

    The top flat face of the mouse body is now replaced with the bluesurf.



    Mouse Buttons

    To create the mouse button etching, create a parallel plane to the x-y plane.
    Sketch a spline on it as shown in figure.
    Click the Project Curve  
    projcurv   tool from the Surfacing toolbar.

    Select the spline as the curve to project.
    Click accept  
    accept[6]   on the ribbon bar.

    Select the top face of the mouse body to project the curve onto.

    Click Finish on the ribbon bar.

    The spline is projected on the top face of the mouse as shown in figure.



    Prepare for a Swept Cutout

    Click the Plane Normal to Curve tool from the Features toolbar.



    Create a Normal Plane

    Create a plane at one end of the projected curve as shown.



    Create the Cross Section

    Sketch a small circle on the nascent plane.



    Take a Swept Cutout

    Create a Swept Cutout   sweptcut   using the circle and the projected curve.



    Its Not All Over

    Zoom into the area where the swept cutout starts.
    The cutout has left some material behind where it started.




    Create a normal cutout again using the same sketch (circle) used for the swept cutout.



    This Looks Better



    Same Story on Far Side

    On the other side, where the swept cutout ends, the case is similar.

    But there is no sketch (circle) to take the normal cutout and to extend the swept cutout far outside the mouse body.

    We need to create a curve to take the cut.



    Derive a Curve

    Click the Derived Curve   dericurv   tool from the Surfacing toolbar.

    Select the edge of the swept cutout.
    Click accept  
    accept[8]   on the ribbon bar.



    Curve is Derived

    The edge is derived as a curve.
    See figure.

    Using this curve, take a normal cutout and extend the swept cut, outside the mouse body.



    Make the Buttons

    Similarly, take two more swept cutouts to make three buttons.



    Merge the Cutouts

    Also extend the cutouts for the mouse button separations where they meet the previous swept cutout.



    Aesthetics, etc.

    Round the sharp edges at the base and top to give the mouse more aesthetic looks, etc.
