Creating Cylindrical Elongated Holes

You can create a cylindrical elongated hole using the Cylindrical Elongated Hole command. A construction arc assists you in creating this element.

Before you begin:

Ensure that Geometric Constraints and Dimensional Constraints are activated in the Sketch Tools toolbar.

Creating Elongated Holes

  1. Click Cylindrical Elongated Hole in the Profile toolbar (Predefined Profile sub-toolbar).

    The Sketch tools toolbar now displays values for defining the cylindrical elongated hole.

  2. Type in the Sketch tools toolbar for the circle center: H=20mm, V=20mm and press Enter.



    The center point will be used to create both the big radius (radius and angle of the cylindrical elongated hole) and the small radius (circular extremities used to define the cylindrical elongated hole).

  3. Type in the Sketch tools toolbar for the arc start point: Start Point: H=30mm, V=10mm and press Enter.

    The arc appears as a construction arc.



    At this step, you may also define the arc big radius R and angle A.

  4. Locate the cursor close to H=10mm and V=30mm

  5. Type in the Sketch tools toolbar for the arc end point : H=10mm and press Enter.



    At this step, you cannot define the arc big radius R and angle A.

  6. Type in the Sketch tools toolbar for the point on cylindrical elongated hole:

    Point on cylindrical elongated hole: H=40mm, V=18mm and press Enter.

    In other words, you are defining what we call the small radius (Radius: 5.958mm). This small radius corresponds to the width of the cylindrical elongated hole, relatively to the circle center.
