It is the language of engineers

Autocad or Computer aided design

is a software application for writing and design 2D and 3D.

Osnap(object snap)

It makes it easier to select a 2d object’s points

1. Endpoint

2. Midpoint

3. Center

4. Perpendicular

5. Intersection

Examples of Osnap

1. Copy

2. Array

3. Move

4. Scale

5. Mirror

6. Stretch

7. Offset

8. Rotate

9. Explode

10. Erase

Examples of Editing

PLINE (polyline) command

creates a chain line with multiple vertexes and straight or circular segments between the vertexes

Hatching

is used to add shaded patterns to objects and shapes within an Autocad drawing.

1. Pattern

2. Angle

3. Points

4. Scale

Hatching Options

Solids

contain the “mass properties” of 3D objects.

1. Box

2. Cylinder

3. Torus

4. Cone

5. Wedge

6. Sphere

Objects accessible in the solids toolbar

Boolean

It is use to make complicated shapes

1. Union

2. Subtract

3. Intersection

Boolean Options

“extrude”

If you ____ a surface into the third dimension, you simply add a thickness in section.

Extrude

This basically is same as creating a “solid” object

World Coordinate System

It is the default coordinate system.

User Coordinate System

Modifications made to the World Coordinate System (WCS) result in a____

1. Floor Plan

2. Section

3. Elevation

4. Roof Plan

5. Septic and Soak Away Details

6. Door and Window Schedule

What are the six drawings that can be produced?

Site Planning

This is the process of creating scenery of land for various purposes.

Working Drawing

It is 2 or 3 dimensional drawing showing all the works and duties that will be done from the beginning of the project to the completion stage.

1. Panel Door

2. Flush Door

3. Roller-shutter (folding) door

4. Revolving Door

5. Swing Door

Types of Doors

1. straight flight staircase,

2. half turn,

3. quarter turn,

4. spiral staircase,

5. helical stair case

Types of Stairs

1. framed windows,

2. fixed windows,

3. casement windows,

4. sliding sash windows,

5. pivoted sash,

6. shutter window

Types of Windows

1. mono-pitch roof,

2. double pitch roof,

3. concrete flat roof,

4. timber-flat roof

Types of Roof

Staircase

is a set of steps or flight leading from one floor to another.

Cantilever Stair

in these types of stair, there is a central reinforced concrete wall and each step cantilevers out of this wall.

Spiral Stair

this is the most economical in terms of space utilization and cost.

Free standing or scissors stair:

similar to half-turn but with suspended half-landing.

Helical Stair

it occupies less space than straight flight and the shape look a helix from floor to floor.

Drawings

encompass the architectural, civil, structural, and mechanical professions, and they are the means of conveying diagrammatic detailed aspects of the design components of a structure.

Architectural drawings

convey the aesthetic and functional aspects of the project and include the fire-rated classification of the structure, occupancy, exiting requirements, and conformance to code of conduct.

Elevations:

These are a pictorial view of each façade of the building indicating windows, doors, etc.

Building sections

A detailed sectional view through the building is taken usually in the project north-south and east-west direction.

Sections and details:

These are a larger-scale dimensional detailed presentation of pertinent construction components and their interface connections with other materials. 

Civil engineering drawings

indicate site and project locations, vehicle accessibility, topography, site drainage, and possibly landscape requirements, although this aspect may be performed by a licensed landscape architect rather than the project architect.

Structural Drawings

indicate the design loads and applicable building code criteria and define the structural framing systems and their supports and foundations.

Mechanical Drawings

designate the heating, ventilating, and air-conditioning (HVAC) systems; electrical distribution requirements; fire and security systems; sprinklers and the necessary plumbing requirements.
