Visualization & Sketching

Three dimensions figures are also referred to as:

Solids

Solids are bound by:

The surfaces that contain them

The four types of surfaces of a solid are:

Planar, single curved, double curved, warped

If the faces of a solid are equal regular polygons, it is called a:

regular polyhedron

What has two bases, which are parallel equal polygons, and three or more additional faces, which are parallelograms?

A prism

What has a polygon for a base and triangular lateral faces that intersect at a common point called the vertex?

A pyramid

What has a single-curved exterior surface?

Cone and cylinder

These three solids all have double curved exterior surfaces

Sphere, torii, oblate (horizontal) and prolate (vertical) ellipsoid

One way to think about the contours of objects is to look at the

contrast between the positive and negative space.

What is used to represent a location in space but has no width, height, or depth

A point

The following are important skills to keep in mind for sketches
and drawings:

Accuracy, Speed, Legibility, Neatness
