Creating new Objects

New objects are added to the
scene by selecting one of the primitive shapes from the Solid:
New menu list

Primitive Shapes |

Rectangle |

Cylinder |

Cone |

Wedge |

Torus |

Sphere |

Stairs |

Dervied Cone |

There are many variations
when adding a new shape, number of sides, texture and lighting styles are
configurable. Torus and sphere shapes have two side dimensions referred
to as U, V (latitude, longitude directions).

Example from New:
Cylinder menu option

Half Shapes

Cylinder, Cone, Sphere, Torus
half shapes

Rounded Edge Shapes

Rectangle, Cylinder with
rounded edges

Torus Options

Wrap
V: When option checked specify start/end to create a partial torus that
does not wrap around 360° and enclose

Square
Ends: Used with Wrap V option, makes torus ends squared off

Partial torus created with Wrap V option and additionally with Square
Ends option on right

Derived
Cone

A cylinder/cone shape can be derived from a surface
consisting of a single convex polygon
selected as Surface A. Base ratio setting in
Derived Cone menu option determines what form cone shapes takes. Values
> 1 result in a widening base, values < 1 create a narrowing base and a
value of 1 derives a cylinder.

Derived cone shapes shown here, note
cone base or top matches the surface it was derived from.
