User interface :

• Ribbon:

1. The Ribbon is a central element of the AutoCAD interface, providing a tabbed

toolbar that organizes commands in a visually accessible manner.

2. It contains various panels, each dedicated to specific tasks such as drawing,

modifying, and annotating.

3. The Ribbon enhances workflow efficiency by grouping related commands

and tools.
 • Command Line:

1. The Command Line is a text-based interface located at the bottom of the

screen.

2. Users can input commands directly, enabling precise control over AutoCAD

functions.

3. It serves as a quick and efficient way to execute commands, especially for

users who prefer keyboard input.

• Model Space:

1. Model Space is the primary workspace where users create and edit the

actual drawing or 3D model.

2. It provides a virtual environment where elements are drafted and

manipulated.

3. Users design and build within the Model Space before organizing the drawing

for presentation in Layouts.

• Layout Tabs:

1. Layout Tabs allow users to create and manage multiple views or layouts

within a single drawing file.

2. Each layout tab represents a separate page, facilitating the organization of

different views, scales, and sheet setups.

3. Users can switch between layouts to work on various aspects of the design

or create different views for presentation.

 • Tool Palettes:
1. Functionality: Tool Palettes provide a customizable interface for accessing
frequently used tools, blocks, and commands. They are organized into tabs and
groups based on specific tasks or project requirements.

commands) from Tool Palettes directly into the drawing area, simplifying the
insertion and application of design elements.
3. Customization: Tool Palettes can be customized by adding, removing, or
rearranging tools and groups to streamline workflows and accommodate user
preferences.

• Viewport Controls:
1. Viewport Creation: Viewport Controls allow users to create and manage
multiple viewports within the layout space. Each viewport displays a
different view of the model or drawing.
2. Viewport Configuration: Users can configure viewports for different
scales, orientations, and visual styles. This flexibility is crucial for creating
detailed drawings or presentations.
3. Viewport Navigation: Viewport Controls include tools for zooming,
panning, and navigating within each viewport, ensuring precise editing
and alignment of elements across different views.
Create New Drawing:

SETTING UP UNITS AND LIMITS:

Units (UN)

• Units define the measurement system for the drawing, such as inches,
millimeters, or feet.

• Accurate units are crucial for maintaining scale and precision in your design.

• AutoCAD provides flexibility to switch between unit systems based on project

requirements.

Limits (LIMITS)

• Limits define the drawing area and help in controlling the size of the drawing
extents.

• Setting appropriate limits ensures that the drawing is contained within a

specific boundary.

• It is essential for controlling the scale and print layout of the final drawing.

layers. Frozen layers are not displayed in the drawing area, while thawed
layers are visible.

• Layer Lock/Unlock (LAYLCK): Prevents editing of objects on selected

layers (lock) or allows editing (unlock). Locked layers protect the
integrity of their contents from accidental modifications.

• Layer Isolate/End Isolation (LAYISO): Temporarily isolates selected

layers for focused editing, hiding all other layers. Ending isolation
restores visibility to all layers previously isolated.
 3. Modification and Organization Tools:

• Layer Merge (LAYMRG): Combines the contents of one layer into

another, streamlining drawing organization and reducing clutter.

• Layer Match (LAYMCH): Applies the properties (such as colour, line

type) of a selected layer to another layer, ensuring consistency across
different parts of the drawing.

4. Visibility Control:

• Layer Off/On (LAYOFF, LAYON): Turns off (hides) or turns on (shows)

the display of selected layers within the drawing. This command is useful
for managing clutter and focusing on specific parts of the design.
Dimensions & Annotations:-

Dimensions and annotations are essential tools in AutoCAD for communicating

design intent and providing critical information within drawings.

Dimensions:

Dimensions in AutoCAD are used to specify and measure the size, position, and
relationships between objects in a drawing. They include linear dimensions
(measuring distances), angular dimensions (measuring angles), radial
dimensions (measuring radii of arcs/circles), and diameter dimensions
(measuring diameters of arcs/circles). Dimensions help ensure accuracy and
provide clear guidelines for constructing and detailing elements within the
design.

Annotations:

Annotations in AutoCAD refer to text, symbols, and other graphic elements

added to drawings to convey additional information or instructions. They
include text annotations for labels and notes, leaders for callouts, and tables for
organizing data. Annotations enhance the clarity and understanding of
drawings by providing context, explanations, and specifications that support the
design intent.

Basic Dimensioning Tools:

. Linear Dimension (DIMLINEAR): Measures distances between points or along

lines.

measured features.

. Radial Dimension (DIMRADIUS): Measures the radius of arcs and circles.

. Diameter Dimension (DIMDIAMETER): Measures the diameter of arcs and

circles.
Advanced Dimensioning Tools:

. Angular Dimension (DIMANGULAR): Measures and displays angles between

lines or segments.

. Baseline Dimension (DIMBASELINE): Creates dimensions from a common

baseline.

. Continue Dimension (DIMCONTINUE): Continues dimensioning without

restarting the sequence.

Annotation Tools:

. Text (TEXT): Inserts text annotations for labels and descriptions.

. Multileader (MLEADER): Adds leader lines with annotation text for callouts.

. Table (TABLE): Inserts tables for organizing and presenting data within the
drawing.

Dimension Style Management:

. Dimension Style Manager (DIMSTY): Customizes dimension styles for

consistent appearance and formatting.

. Override Dimension Style (DIMOVERRIDE): Temporarily modifies specific

dimension properties.

Editing and Adjusting Annotations:

. Edit Text (DDEDIT): Allows direct editing of text within dimensions and
annotations.

. Move Dimension (DIMMOVE): Moves dimension objects while maintaining

associativity with measured geometry.
