The Base Form group defines the original particle grid – called a 'Base Form' – that can be affected by layer maps, particle controls, dispersion fields and every other control in Form. You have control over the size, particle density, position and rotation of the base form in 3D space.
This defines the starting point of your particle form. All of the base shapes can have multiple copies by setting Particles in Z to a value greater than 1.
Size X, Size Y, Size Z
Sets the size of the form in the X, Y and Z axes. The X and Y dimensions correspond to the size of the form horizontally and vertically, while the Z value determines its depth. Size Z and Particles in Z work together to control the density of the overall form.
At left, Size X at 400, Size Y at 250, Size Z at 1700.At right, Size X at 1200, Size Y at 300, Size Z at 800.
Particles in X, Particles in Y, Particles in Z
Sets the number of particles used to generate the form along the X, Y and Z axes. Render times are directly proportional to the number of particles. Often a particle density of only a few hundred is needed to clearly define a form.
Be careful of high Z values, because the Z value essentially replicates the grid, strings, or sphere, and can cause very slow rendering. Typically, you only need a Z value of 1 to create an interesting surface shape.

Center XY, Center Z
Positions the form in space. Note that this positioning takes place BEFORE the different distortion fields (Fractal Field and Spherical Field) are applied, so the controls here in effect move the form through the fields. If you'd rather move the whole thing with fields applied, use the Offset settings in the Transform World controls instead.
X Rotation, Y Rotation, Z Rotation
If you would rather rotate the whole form with fields applied, use the Rotation settings in the Transform World controls instead.
Left to right, X Rotation is 0 and 100.
