Display Units
Values are displayed together with their unit of measurement by default. If this option is disabled, the
unit of measurement is not displayed.
Use HPB System
You may nd this option useful if you are an experienced animator. If this option is disabled, the active
object rotates about its local axes or the world axes when you use the mouse. However, when you
play back the animation, the object may not rotate as planned. This is because CINEMA 4D records
all rotations using the HPB system.
If, on the other hand, you enable this option, the active object rotates about the HPB angles when
you use the mouse. In other words, you rotate the object using the heading, pitch and bank of the
object’s parent system. Only experienced animators should use this option, since it requires a great
deal of abstract thought.
Basic Units
Here you determine the basic unit of measurement in CINEMA 4D. Choose from pixels, kilometers,
metres, centimeters, millimeters, micrometers, nanometers, miles, yards, feet and inches.
For example, if you select Centimeter as the basic units, all position values will be stated in cm. Note
that if you change units the numerical values will not be converted. However, you can enter values in
different units. For example, if the basic units are cm and you type ‘5 km’ into a dialog, the value will
be converted to 500,000 cm.
