What it is Othographic Projection?

• drawings made with instruments or computers

• a type of drawing that depicts an object in a 2-dimensional way

• a technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table

• the relationship between one object and another

The definition of PLANES according to Design and Modeling

• a flat surface on which a straight line joining any two points on it would wholly lie

• a level of existence, thought, or development.

• (of a bird or an airborne object) soar without moving the wings; glide

• 6 sides that can define an object

Which of the following is not a Line in the Alphabet of Lines?

• Visible Line

• Hidden Line

• Phantom Line

• Angular Line

Direct Modeling

• involves engineers building up a 3D geometry piece by piece.

• offers designers a what-you-see-is-what-you-get approach to building and editing their models.

• a three-dimensional space consists of an ordered triplet of lines (the axes) that go through a common point (the origin) and are pair-wise perpendicular

• most often used on circular objects and use an angled cutting plane line

Define RENDERING according to Design and Modeling

• a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts

• a performance of a piece of music or drama.

• the action of giving, yielding, or surrendering something

• the process of using color and shading in order to make it appear solid and three-dimensional

Alternative Position View

• indicate the range of motion of an assembly component by showing it in different positions

• allows you to define portions of an existing standard, general or section view and then break that view for display on the drawing sheet

• drawing that shows corrections or changes to a previous drawing

• revised set of drawings submitted by a contractor
