By default, the initial orientation is set to 0, 0, 0, which orients the hinge
constraint to lie parallel to the Z-axis in world space. By setting the
orientation to 90 in the Y-axis, the hinge constraint is rotated 90 degrees
around the Y-axis, which orients the constraint parallel to the X-axis.
By leaving the Set Initial Position at its default setting, the hinge
constraint is created at the rigid body’s center of mass.
3 Select pCube1 and click Apply in the Constraint Options.
4 Select pCube2 and click Apply in the Constraint Options.
5 Repeat this until each of the six planks has a constraint applied to it.
6 Close the Constraint options window.
Running a dynamics simulation
In the next steps, you create a ball and add gravity to make the ball drop and
hit the planks and then playback the simulation.
To create a ball for the simulation
1 Select Create > Polygon Primitives > Sphere >
.
2 Set Radius to 0.2 and click Create.
3 In the Channel Box, set the Sphere’s Translate Y value to 18.
To add gravity attributes to the ball
➤ With the sphere still selected, select Fields > Gravity.
When you connect Gravity to the sphere, it automatically makes the
sphere an active rigid body. Gravity affects only the object that was
selected when you add the Gravity field.
To run the dynamics simulation
➤ In the Time and Range slider, play the animation.
