Area/Volume

Calculate the area, volume, mass, and moments of inertia of one or more objects. If an object isn't a closed solid, open edges are displayed in red.

Calculate the Area and Volume

Calculate the area and volume of one or more objects.

If you select multiple surfaces that enclose a solid region, Inspire Studio automatically sews the surfaces together to calculate the volume of the solid. For example, if you select the faces of a cube, Inspire Studio automatically sews the faces together to calculate the volume of the cube.

  1. On the ribbon, click the Analysis tab.
  2. Click the Area/Volume icon.
  3. Click an object.
    Note: To select multiple surfaces, box select them.
  4. Choose from the following options:
    OptionDescription
    Units > Length Choose from the following units:
    • mm
    • cm (default)
    • in
    • ft
    Units > Volume Choose from the following units:
    • mm3
    • cm3 (default)
    • m3
    • in3
    • ft3
    • ml
    • cl
    • l
    Sew Tolerance Sew tolerance is used to sew adjacent edges. By default it is set to 0.001 cm. Change the method to custom to set a custom tolerance value. A higher value is more forgiving but less accurate.

  5. The following information is displayed:
    ParameterDescription
    Mass The mass, based on the density and the units for mass.
    Moments of Inertia
    • Ixx Iyy Izz: The moments of inertia about the axes oriented as global x, y, z and passing through the center of mass.
    • Iyz Ixz Ixy: The products of inertia about the axes oriented as global x, y, z and passing through the center of mass.
    • Principal moments: The moments of inertia about the three principal axes.
    • Principal axis X: The x, y, z coordinates of the first principal axis.
    • Principal axis Y: The x, y, z coordinates of the second principal axis.
    • Principal axis Z: The x, y, z coordinates of the third principal axis.
