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.

Compound objects include the following object types: Morph Compound Object Scatter Compound Object Conform Compound Object Connect Compound Object BlobMesh Compound Object ShapeMerge Compound Object Boolean Compound Object Terrain Compound Object Loft Compound Object Mesher Compound Object ProBoolean Compound Object ProCutter Compound Object
Loft objects Loft objects are two-dimensional shapes extruded along a third axis. You create loft objects from two or more existing spline objects.
Boolean Operations â€˘
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 â€˜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:
Now create a sphere (bigger than the cylinder). Go to compound objects and select the cylinder. Select â€˜scatter', and pick the distribution object: the sphere.
1 create a cylinder:
2 5 apply a taper and a bend modifier:
