Creating Orthographic
Projections in AutoCAD
Summary

Summary
 What will we learn in Chapter 3?
→ The tools necessary to draw an
orthographic projection in AutoCAD.
 Key points
→ AutoCAD uses layers to help organize line
types and weights.

Restricted use only
3.1) Introduction

Restricted use only
Introduction
 Line types and line weights give valuable
information to the print reader.

Restricted use only
Introduction
 AutoCAD enables you to create different
line types and to print using different line
weights.
 This is accomplished through the use of
layers.

Restricted use only
3.2) Layers

Restricted use only
Layers
 Layers are like transparencies, one laid
over the top of another.
→ Each layer contains its own line type.
→ The line color controls the printed line
thickness.

Restricted use only
Layers
 Let’s use
layers to
organize
this
drawing.

Restricted use only
The Layers Panel

Restricted use only
The Layer Properties Manager

Restricted use only
3.3) Line Type Scale

Restricted use only
Line Type Scale
 LTSCALE: Controls the size of the
dashes and the spaces between dashes
or dots.

Restricted use only
3.4) Properties

Restricted use only
Properties
 The properties of an individual object may
be changed by selecting the object and
then selecting the Properties icon in the
View tab - Palettes panel.

Restricted use only
The Properties Panel
 If these properties need to be changed,
your first action should be to use layer
properties.
→ This creates a much more organized
drawing.

Restricted use only
3.5) Printing using Pen Widths

Restricted use only
Printing using Pen Widths
 Object color is used to control the print
thickness of the object.
→ Access the Page Setup window to assign
thickness’ to the different colors.

3.7) Title Blocks

Restricted use only
Title Blocks
 Every engineering drawing should have
both a border and a title block.
→ Border - defines the drawing area
→ Title block - gives pertinent information
 The information that is included depends
on the drawing type, field of engineering,
and viewing audience.

Restricted use only
Title Block
 A title block may include:
→ Name of drafter
→ Checked by
→ School or Company
→ Drawing title
→ Part name
→ Part number
→ Material of part
→ Number of required parts
→ Sheet number
→ Number of sheets
→ Scale of drawing
→ Date
→ Last revision

Restricted use only
3.8) Blocking

Restricted use only
Blocking
 Commands used
→ BLOCK: Allows you to create a grouping of
objects that can be used repeatedly in the
current drawing.
→ WBLOCK: This command writes a BLOCK
to a file. This allows you to use the BLOCK
in all drawings not just the current one.

Restricted use only
Blocking
 Commands used
→ INSERT: Allows you to retrieve a BLOCK
or WBLOCK.
→ EXPLODE: (Modify panel ) Allows you
to separate a BLOCK into its individual
parts.

3.10) Model and Layout Space

Restricted use only
Model and Layout Space
 Model Space:
→ In model space, you draw your
design/model at a 1:1 scale.
 Layout/Paper Space:
→ The model is scaled to fit on the paper used
to print the drawing (usually 8.5 x 11).

Restricted use only
 Model Space:
→ One view direction.
→ Multiple view directions through the use of
view ports.

Restricted use only
 Viewports:
→ A viewport is a rectangular window that
views the object from a specified line of
sight.
→ Viewports are most useful when working
with a 3-D model.
• You can create several viewports that view the
3-D model from several different vantage points.

Restricted use only
 Model Space:
→ Annotations (dimension, text) may be
included on 2-D drawings and one view 3-D
drawings.
→ Annotations may be included in any view
port.

Restricted use only
 Model Space:
→ Annotations will not scale automatically.
→ Annotations will scale automatically if the
object is defined as annotative.
