Erase Removes an object or selected objects<br />

Extrude An operation which transforms 2D objects into 3D by forcing<br />

out <strong>the</strong> plan view <strong>of</strong> <strong>the</strong> object into a specified height.<br />

Flexibility The quality <strong>of</strong> <strong>the</strong> s<strong>of</strong>tware to be adaptable or variable<br />

General Purpose S<strong>of</strong>tware designed to be useful for a broad range <strong>of</strong> tasks or<br />

S<strong>of</strong>tware domains<br />

Geometric Modifies <strong>the</strong> properties <strong>of</strong> <strong>the</strong> objects, such as shape,<br />

Transformations coordinates or angle, apart from its topology. ‘Move’, ‘rotate’,<br />

‘scale’, ‘reflect’ and ‘shear’ transformations are some <strong>of</strong> <strong>the</strong><br />

examples.<br />

Global Rendering A rendering method that allows having a real time rendering<br />

by taking account <strong>of</strong> every single light source reflecting from<br />

each objects on <strong>the</strong> scene. It is such a technique that advances<br />

illumination from one environmental light source to many light<br />

sources in order to calculate shading more accurately.<br />

Grids A two-dimensional structure made up <strong>of</strong> a series <strong>of</strong><br />

intersecting vertical and horizontal axes used to structure<br />

content in a drawing<br />

Grouping Provides grouping <strong>of</strong> 2D or 3D objects as if <strong>the</strong>y react like one<br />

object.<br />

Hatching To shade <strong>the</strong> defined areas by drawing or etching fine parallel<br />

or crossed lines on<br />

Hidden Line Removes any line hidden from view assuming surfaces are<br />

opaque.<br />

Interface A boundary physical or logical, between two physical or<br />

logical systems: e.g. a person and a computer<br />

Interoperability The ability to exchange and use information between different<br />

s<strong>of</strong>tware to communicate<br />

Intersect Operation Creates an object from <strong>the</strong> overlapping geometry <strong>of</strong> two<br />

objects<br />

Isometric View It is a method <strong>of</strong> visually representing three-dimensional<br />

objects in two dimensions, in which <strong>the</strong> three coordinate axes<br />

appear equally foreshortened and <strong>the</strong> angles between any two<br />

<strong>of</strong> <strong>the</strong>m are 120°<br />

Layer Used to categorize information in a drafting system<br />
