An introduction to drafting in 3 Dimensions

Introduction - Why 3-D?

You may have already figured out why CAD has many advantages over manual drafting. One large advantage is that once you lot've fatigued something, you shouldn't have to describe information technology again. If yous manually drew a house program, you lot would take to draw a front elevation, side elevations, and possibly a perspective view. With one iii-D CAD model, you can generate views from any angle either inside or outside the house and animations. After, if your client needs something changed, you can and so brand the changes once and re-render your views. If you're drawing mechanical parts, you can generate virtual prototypes or even create rapid prototypes. In this manner Boeing was able to blueprint and paradigm the 777 jetliner. This level of engineering would be impossible without CAD.

Your company may non do a lot of 3D piece of work, merely information technology is nonetheless a good skill to have and it's as well more fun than 2d.

Yous'll exist learning the iii-D concepts in the post-obit order:

Isometric Drawings (not truthful 3D)

Wire-frame (very bones 3D)

Surfaces / Regions (primitive 3D)

Solid Objects (advanced 3D)

You will have a adventure to draw the same object different means to see the differences between the various methods.

Earlier inbound the exciting world of 3-D, you'll have to learn some more than CAD terminology. This level presumes that you accept a proficient understanding of second commands.

3-D CAD TERMINOLOGY

2-D	A concept of displaying existent-world objects on a flat surface showing merely height and width. This organization uses but the 10 and Y axes.
3-D	A way of displaying real-globe object in a more than natural mode past calculation depth to the superlative and width. This system uses the X Y and Z axes.
Boolean operations	Commands that let y'all to add, subtract or intersect solid objects in AutoCAD.
Circuitous surface	By and large a curved surface. Examples: car fender, landscape contour.
Meridian	The difference between an object existence at zero on the Z-axis and the height that it is above zero.
Extrude	The extrude command raises the shape of a 2nd outline into a 3D solid. For case, a circle would be extruded into a cylinder.
Face	The simplest truthful 3-D surface.
Facet	A three or 4 sided polygon that represents a piece (or section) of a three-D surface.
Hidden line removal	A way of hiding lines that would not be visible if y'all were viewing the actual object you have drawn in AutoCAD. (Command: HIDE)
Isometric Drawing	A elementary way of achieving a '3-D' appearance using ii-D drawing methods.
Plan View	Too known as the top view, a plan view looks straight down the WCS Z-centrality to the X-Y centrality.
Primitive	A basic solid building block. Examples would exist 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 lot have created.
Shading	A quick style of adding color to a three-D object y'all accept drawn. (Command: SHADE)
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 iii-D model divers past surfaces. The surface consists of polygons. (Meet facets.)
Thickness	A property of lines and other objects that gives them a iii-D similar appearance.
UCS	The user according organization. This is defined by the person drawing to have easier admission to portions of a 3-D model.
View	A particular view of the object you accept created.
Viewport	A window into your drawing showing a particular view. Yous can have several viewports on your screen. Different from the viewports used in plotting.
Wire-frame Model	A iii-D shape that is defined by lines and curves. A skeletal representation. Hidden line removal is non possible with this model.
Z-Axis	The third centrality that defines the depth.

As computers and software become more powerful, working in 3D becomes more popular. You lot take more than power in desktop automobile today, than was dreamed of when CAD first appeared. Be prepared that y'all will probable need to learn 3D at some signal in your career. One time you are comfortable working in 3D, you'll find that yous volition rarely want to draw in 2nd once more. Autodesk (the makers of AutoCAD) make other products designed specifically for certain disciplines - Revit, AutoCAD Compages, AutoCAD Civil 3D, 3ds Max and more. Depending upon your budget and needs, you may need to wait into programs like these. The concepts taught in these lessons will help you when you piece of work in any 3D program.

Reference: Have a wait at some AutoCAD renderings before you commencement in this new globe.

​​Fun fact: In 1994 over 2,000 independent developers worked to create specialized applications using Autodesk programs.
