3. Vertex—Turns on Vertex sub-object level, which lets you select a
vertex beneath the cursor; region selection selects vertices within the
region.
Edge—Turns on Edge sub-object level, which lets you select a face
or polygon edge beneath the cursor; region selection selects multiple
edges within the region. When Edge sub-object level is on, hidden
edges are displayed as dashed lines, allowing for more precise
selection.
Face—Turns on Face sub-object level, which lets you select a
triangular face beneath the cursor; region selection selects multiple
triangular faces within the region.
Polygon—Turns on Polygon sub-object level, which lets you select
all coplanar faces (defined by the value in the Planar Threshold spinner)
beneath the cursor. Usually, a polygon is the area you see within the
visible wire edges. Region selection selects multiple polygons within the
region.
Element—Turns on Element sub-object level, which lets you select
all contiguous faces in an object. Region selection lets you select
multiple elements.

Loft objects
Loft objects are two-dimensional shapes extruded along a third axis.
You create loft objects from two or more existing spline objects.

7. Boolean Operations
• The Boolean objects combine two other objects by performing a Boolean
operation on them: union, subtraction and intersection. To perform the operation
select the first object (operand A) and go to ‘compound objects->Boolean' select
the operation:
and click the second object (operand B):

What the operation does? Let's understand it with an example with 2 spheres
but if you had read the splines tutorial you know it :-) The original spheres:
after the Boolean operations:
8. Now create a sphere (bigger than the cylinder). Go
Scatter to compound objects and select the cylinder. Select
‘scatter', and pick the distribution object: the sphere.
