Dynamics

Open the ﬁle QS_Dynamics_start.c4d.

The scene contains an oldtimer, which we will equip with a motor using only a few objects and by modifying a

couple of settings, which will cause the car to drive.

As you can see, a polygon object was used to create the car body and the wheels. We could have created the

scene using individual objects for each wheel but to keep things simple for this tutorial we simply used four

Primitives. All we have to do now is link the tires with the car body and make the tires rotate using a Motor

object.

First, create a Motor and two Connectors from the main menu: Simulate/Dynamics.

Select all three elements in the Object Manager and set their H rotation angle collectively to 90°.

This will ensure that all three objects have the same orientation as the wheels.

Next, rename the Connectors to Connector_front and Connector_back, respectively, and make them Child

objects of the wheels_front and wheels_back objects, accordingly. After doing so, set all three position values

(X, Y, Z) for the Connectors to zero in the Coordinates Manager (don’t forget to click on Apply when ﬁnished!).

Make the Motor object a Child object of the polygon object car.

Zeroing out the position values again will not be necessary. Now that the objects have their positions and

orientation deﬁned all we have to do is deﬁne the dependencies of the elements. The fastest way to do this is:

Select the objects Motor, Connector Front and Connector_back in the Object Manager (Ctrl/Cmd + click for

multiple selections).

Two ﬁelds will be made available in the Attribute Manager - Object A and Object B. These ﬁelds can be used

to link objects. We have to tell the Motor object and the Connectors that they have to link to the car body and

wheels.

Drag the wheels_back object into the Object A ﬁeld and drag the car object into the Object B ﬁeld.

This will create the links for all three objects.
