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.




    t0400

    Visualize First


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

     


    t0401

    Sketch It


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

     

    t0403

    Visualize Again


    From left, its like this.

     

    t0402

    Sketch the Other View


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

     

    t0404

    Prepare for BlueDot


    Click the BlueDot   bluedot   tool from the Surfacing toolbar.


    Click the two splines one after the other.

     




    t0405

    Tie the Splines


    Click Finish on the ribbon bar.


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

     




    t0406

    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.

     




    t0407

    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.

     


    t0408

    Create the Body


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

     

    t0409

    Display the Surface


    Display the previously hidden bluesurf.

     

    t0410

    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.

     




    t0411

    The Replacing Face


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

     

    t0412

    Face is Replaced


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

     

    t0413

    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.

     





    t0414

    Prepare for a Swept Cutout


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

     

    t0416

    Create a Normal Plane


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

     

    t0415

    Create the Cross Section


    Sketch a small circle on the nascent plane.

     

    t0417

    Take a Swept Cutout


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

     

    t0418

    Its Not All Over


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

     

    t0419

    Rectification


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

     

    t0420

    This Looks Better

     

    t0421

    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.

     



    t0422

    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.

     


    t0423

    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.

     

    t0424

    Make the Buttons


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

     

    t0425

    Merge the Cutouts


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

     

    t0426

    Aesthetics, etc.


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