Creating Splines

You can create a spline either by clicking or using the Sketch tools toolbar options. You can control the curvature of spline using control points.

Before you begin:

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

  1. Click Spline in the Profile toolbar (Spline sub-toolbar).

  2. Click in the geometry area to indicate the control points through which the spline goes or if you know where these points must be located, use the Sketch tools toolbar which now displays different value fields for defining the points coordinates.

    These value fields are:


    • H: horizontal

    • V: vertical

  3. For the purposes of our scenario, in the Sketch tools toolbar enter the first control point coordinates: H=30mm, V=40mm and press Enter. The first point is created.

  4. Position the cursor in the desired fields to key in the desired values and press Enter. For example, enter:


    • Control Point (H: 5mm and V: 5mm)

  5. Repeat the operation to define three additional points:


    • Control Point (H: 23mm and V: 8mm)
    • Control Point (H: 35mm and V: 14mm)
    • Control Point (H: 56mm and V: 8mm)

  6. Double-click the last point you have created to finish the spline creation.



    Tips:
    • Clicking again on Spline or another command also ends the spline creation.
    • Constraints are assigned to this profile on the condition that:
      • You activated Dimensional Constraints in the Sketch tools toolbar before starting the scenario.
      • You entered coordinate values in the fields (you did not create the profile just by clicking).
