    In this tutorial you learn two important modeling techniques :

  • How to create a regular polygon of any number of sides in Solid Edge.
  • How to constrain a revolved cutout so that it never fails.

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

    Regular Polygon - Begin Sketching

    Start with creating a sketch     in the x-y plane.

    Draw a circle with its centre at the midpoint of one of the reference planes.


    Using the Construction     tool, toggle the circle to construction.

    Irregular Polyogn

    Using the Line     tool, create an irregular polygon.

    Draw the lines on the construction circle, so that the endpoints are connected to the circle.

    Avoid Relations

    Take care that new points are not horizontally or vertically aligned with existing points.

    See figure.

    Last Point

    Draw six lines to create a hexagon.

    Take care that the last point clicked is on the end-point of the first line and not on the circle.

    See figure.

    Make Regular

    Click the Equal     geometric relationship tool.

    Make the first line equal to the second line in the irregular polygon.

    See figure.

    Make Regular - Carry On

    Similarly, make the second line equal to the third line.

    and so on...

    Make Regular - Finish

    Finally, all sides of the polygon are equal.

    This makes the polygon a regular one.

    Make Horizontal

    If the polygon looks a little tilted, make one of its sides horizontal.

    Click the Horizontal/Vertical     geometric relationship tool.

    Select a line to make horizontal.

    Make Horizontal - Done

    Since all the lines are connected to the circle and fully constrained, the hexagon rotates.

    Your figure should now look as shown.

    Hexagon Dimension

    Apply a Smart Dimension     to the circle.

    This dimension will control the size of the hexagon.

    Isn't that coooool !

    Hexagon Dimension - Tets It

    Change the dimension to a upper or lower value.

    The hexagon should :

  • Update accordingly.

  • All lines should remain inside the circle.

  • The hexagon should not rotate.

  • Make a Nut

    Start the Protrusion command and select the hexagon as shown in figure.

    Make a Nut - Finish

    Complete the Protrusion.

    Revolved Cut - Begin

    Click the Revolved Cut     tool on the Features toolbar.

    Select one of the vertical planes.

    Revolved Cut - Plane Select

    Choose the plane such that two faces of the nut are visible in the sketcher.

    This is important.

    See figure.

    Revolved Cut - Plane Check

    If you picked a plane and three faces of the nut are seen in the sketcher then,

    Click Finish in the sketcher immediately and return to the model.

    Click the other vertical reference plane.

    Axis of Revolution

    Click the Axis of Revolution     tool and select the middle vertical edge of the nut.

    See figure.

    Draw Line

    Click the Line     tool and draw a line as shown in figure.

    The first endpoint of the line should be connected to the vertical reference plane.

    Angular Dimension

    The other endpoint of the line should be connected to the end of the nut as shown.

    Apply an angular dimesion of 30 deg to the line as shown in figure.

    Exit Sketcher

    Click Finish on the ribbon bar.

    Indicate the direction as shown in figure.

    All Round Cut

    Click the Revolve 360     option on the ribbon bar.

    You will get the chamfer as desired.

    The beauty of this approach is that the cut always remains as desired without adjusting any dimensions.


    The only dimension to change is the diameter of the construction circle and the whole nut updates.

    This way you can also create regular polygons whose side can number between 3 and .....
