Drawing Spline driven by mathematical equations using the Equation Driven Curve tool of SOLIDWORKS

You can create spline driven by two type of mathematical equations: Explicit and Parametric by using the Equation Driven Curve tool of SOLIDWORKS.

Procedure to Draw  mathematical equations driven Spline by using the Explicit equation type

1. Invoke the Equation Driven Curve PropertyManager by clicking on the Equation Driven Curve tool in the Spline flyout.

2. Make sure that the Explicit radio button is selected in the Equation Type rollout of the Equation Driven Curve PropertyManager.

3. Enter the equation for Y as the function of x in the Yx field of the Parameters rollout. For example, enter the equation 2* sin(x)^12 in the Yx field.

4. Enter the start and end value of the function x in the x1 and x2 fields of the Parameters rollout. For example, enter 0 in the x1 field and 38 in the x2 field as the start and end values of the function x.

5. Press ENTER, the preview of the equation driven cover appears in the drawing area. Next, click on OK to accept the creation of curve and to exit from the PropertyManager. Below figure shows a explicit equation type spline drawn.

Procedure to Draw mathematical equations driven Spline by using the Parametric equation type

1. Invoke the Equation Driven Curve PropertyManager by clicking on the Equation Driven Curve tool in the Spline flyout.

2. Select the Parametric radio button in the Equation Type rollout. As soon as you select the Parametric radio button, the Parameters rollout of the PropertyManager modified as shown in below figure.

3. Enter the equations for X and Y as the function of t in the Xt and Yt fields of the Parameters rollout, respectively. For example, enter (t + sin(t)^2) in the Xt field and 2* sin(t) in the Yt field.

4. Enter the start and end values of the function t in the t1 and t2 fields of the Parameters area. For example, enter 0 in the t1 field and 38 in the t2 field as the start and end values of the function t.

5. Press ENTER, the preview of the equation derived spline appears in the drawing area. Next, click on OK to accept the creation of spline and to exit from the PropertyManager. Below figure shows a parametric equation type cover drawn.
