A combined linear and angular motion is defined:

m = new Motion("Combined Linear/Angular");

m1 = m.motionComponent("Linear");

m1.setDirection(0, 1, 0);

m1.initialPosition = 0;

p = m1.property("Distance");

v = p.variation("Reciprocating");

v.setValue("Half Period Time", 25, "second");

v.setValue("Distance", 500, "millimeter");

p.apply(v);

m2 = m.motionComponent("Angular");

m2.setAxisOfRotation(0, 1, 0);

m2.setCenterOfRotation(0, 0, -100);

m2.initialPosition = -40;

p = m2.property("Angle");

v = p.variation("Oscillating");

v.setValue("Half Period Time", 6, "second");

v.setValue("Angular Displacement", 80, "deg");

p.apply(v);

a.select("RADAR");

a.applyMotion(m);

A line-by-line description of creating a combined linear/angular motion follows:

A motion object called “m” is created, and set to type Combined Linear/Angular:

m = new Motion("Combined Linear/Angular");

A motion object called “m1” is created, and is used to define the Linear component of the motion. The direction of travel and the initial position are defined:

m1 = m.motionComponent("Linear");

m1.setDirection(0, 1, 0);

m1.initialPosition = 0;

A property object called “p” is created, and is used to define the Linear component of this motion. The distance of travel is defined as reciprocating using a variation object called “v”:

p = m1.property("Distance");

v = p.variation("Reciprocating");

v.setValue("Half Period Time", 25, "second");

v.setValue("Distance", 500, "millimeter");

p.apply(v);

The angular component of the motion is defined by first creating a motion object called “m2”, and setting to angular. The geometric parameters of angular motion are then set. The angular motion is defined by creating a property object called “p”, and defining the angular motion to be oscillating.

m2 = m.motionComponent("Angular");

m2.setAxisOfRotation(0, 1, 0);

m2.setCenterOfRotation(0, 0, -100);

m2.initialPosition = -40;

p = m2.property("Angle");

v = p.variation("Oscillating");

v.setValue("Half Period Time", 6, "second");

v.setValue("Angular Displacement", 80, "deg");

p.apply(v);

The command is finished by selecting the part called “Radar”, and assigning the motion defined in the motion object m:

a.select("RADAR");

a.applyMotion(m);
