1 INTRODUCTION TO 3-D 3-D CAD TERMINOLOGY 2-D
A concept of displaying real-world objects on a flat surface showing only height and width. This system uses only the X and Y axes 3-D A way of displaying real-world object in a more natural way by adding depth to the height and width. This system uses the X Y and Z axes. Boolean operations Commands that allow you to add, subtract or intersect solid objects in AutoCAD. Complex surface Generally a curved surface. Examples: car fender, landscape contour. Elevation The difference between an object being at zero on the Z-axis and the height that it is above zero. Teknologi dan Rekayasa

2 INTRODUCTION TO 3-D 3-D CAD TERMINOLOGY Extrude
The extrude command raises the shape of a 2D outline into a 3D solid. For example, a circle would be extruded into a cylinder. Face The simplest true 3-D surface. Facet A three or four sided polygon that represents a piece (or section) of a 3-D surface. Hidden line removal A way of hiding lines that would not be visible if you were viewing the actual object you have drawn in AutoCAD. (Command: HIDE) Isometric Drawing A simple way of achieving a '3-D' appearance using 2-D drawing methods. Teknologi dan Rekayasa

3 INTRODUCTION TO 3-D 3-D CAD TERMINOLOGY Plan View
Also known as the top view, a plan view looks directly down the WCS Z-axis to the X-Y axis. Primitive A basic solid building block. Examples would be boxes, cones, cylinders. Region A 2-D area consisting of lines, arcs, etc. Rendering A complex way of adding photo-realistic qualities to a 3-D model you have created. Shading A quick way of adding color to a 3-D object you have drawn. (Command: SHADE) Teknologi dan Rekayasa

4 INTRODUCTION TO 3-D 3-D CAD TERMINOLOGY Solid Model
A 3-D model creating using solid 'building blocks'. This is the most accurate way of representing real-world objects in CAD. Surface Model A 3-D model defined by surfaces. The surface consists of polygons. (See facets.) Thickness A property of lines and other objects that gives them a 3-D like appearance. UCS The user co-ordinate system. This is defined by the person drawing to have easier access to portions of a 3-D model. View A particular view of the object you have created. Teknologi dan Rekayasa

5 INTRODUCTION TO 3-D 3-D CAD TERMINOLOGY Viewport
A window into your drawing showing a particular view. You can have several viewports on your screen. Different from the viewports used in plotting. Wire-frame Model A 3-D shape that is defined by lines and curves. A skeletal representation. Hidden line removal is not possible with this model. Z-Axis The third axis that defines the depth.
