    About CAD

    Computer-Aided Design(CAD) or Computer-Aided Design and Drafting (CADD) can be defined as using computer systems to assist in the creation, modification, analysis, or optimization of a design. (Narayan, 2008)

    CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and create a database for manufacturing. (Narayan, 2008)

    This sample image is a screen chaptered image from one of the early versions of AutoCAD. Compare with the current version of AutoCAD, this version is many simple functions and fewer icons on the interface.

    CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design, prosthetics, and many more. (Pottmann, and et al., 2007)

    About AutoCAD

    AutoCAD is an industry-leading commercial CAD software.

    AutoCAD is used by AEC(Architecture, Engineer, and Construction) to generate and optimize 2D and 3D designs. AutoCAD is a widely used software program that can help you draft construction documentation, explore design ideas, visualize concepts through photorealistic renderings, and simulate how a design performs in the real world. (Autodesk)

    AutoCAD was first released in December 1982 as a desktop app. In 2010, AutoCAD was released as a mobile- and web app, marketed as AutoCAD 360. (Autodesk and AutoCAD)

    Four AutoCAD products for AEC

    • AutoCAD: the original version of AutoCAD. This version can use architects, project managers, engineers, graphic designers, city planners, and other professionals.
    • AutoCAD Architecture: a version of Autodesk’s flagship product, AutoCAD, with tools and functions specially suited to architecture work. This software supports dynamic elements (wall, door, windows, and other architectural elements) and automatically updating Spaces and Areas for calculations of sqft.
    • AutoCAD LT:  the lower-cost version of AutoCAD, with reduced capabilities (No 3D, No Network Licensing, No management tools, and more).
    • AutoCAD 360: an account-based mobile and web application enabling registered users to view, edit, and share AutoCAD files via a mobile device and web using a limited AutoCAD feature set and using cloud-stored drawing files.

    Architects and Designers use AutoCAD in slightly different ways. It is different from firm to firm and depending on who draws the drawing. Moreover, it depends on what phase of the design you are in.

    Many design firms never use layout tabs. Some firms use AutoCAD only for Schematic Design purposes. Some designers use this application for presentation purposes too.

    However, in this course, we are targeting to use all essential functions to generate a Construction Document set.

    Below is a typical – fundamental – Construction Document set for an interior design project

    • Cover sheet + general project information
    • Floor plans
    • Furniture + Finish plans
    • Ceiling plans
    • Elevations + Sections
    • Details

    For detailed information about the types of drawings, please refer
    Kilmer, W. Otie, and Kilmer, Rosemary. Construction Drawings and Details / W. Otie Kilmer and Rosemary Kilmer. Third ed. 2016. Print.

    (CO7) Understand essential drawing tools- Origin and Rectangle

    Thumbnail for the embedded element "01 - Introduction of AutoCAD - CO 7 - Understand basic drawing tools"

    A YouTube element has been excluded from this version of the text. You can view it online here: https://iastate.pressbooks.pub/visualgraphiccomm/?p=5

    Understand the “origin” of the drawing

    AutoCAD drawing area is on a real scale, which means the drawing scale is 1:1 scale. Moreover, the drawing area is unlimited. You can draw the entire earth in the drawing. Furthermore, you can draw a small object, too. Designers often lose the point/location that they want to draw in the drawing when you draw in a big drawing. Thus, designers use the drawing origin (0,0,0) – ((x,y,z) for a 3D model) as the base point of the project. Usually, the origin of the drawing is the left-bottom corner on the first floor (if it is a 3D model). In AutoCAD, we use only (0,0) – (x,y).

    To start your drawing, draw a building footprint or property line first.

    • [STEP 1] Click [Rectangle] on the Home Ribbon, or type [rec] and Enter
    • [STEP 2] Specify the first point, type [0,0] and Enter
    • [STEP 3] Specify the next point. Any point on the right-top corner will be fine. It depends on the project size. For our project, type [58’7″,20’4″]
    • [STEP 4] Type [z] to zoom and type [a] and EnterThis image shows the building outline that draws with the rectangle tool. The size of the building outline is 58foot 7inches and 20foot 4inches.

    Line (command)

    • [STEP 1] type [l] and Enter
    • [STEP 2] specify the first point by clicking a point or typing [x,y]
    • [STEP 3] specify the end point by clicking a point or typing [x,y] – absolute point, type [@x,y] – relative point
    • Please refer to this link for the line command

    Move (command)

    • [STEP 1] type [m] and Enter
    • [STEP 2] select the object/objects that you want to move and Enter
    • [STEP 3] specify the base point
    • [STEP 4] specify the second point to move the object/objects
    • Please refer to this link for the move command

    Copy (command)

    • [STEP 1] type [co] and Enter
    • [STEP 2] select the object/objects that you want to copy and Enter
    • [STEP 3] specify the base point
    • [STEP 4] specify the second point to copy the object/objects
    • [STEP 5] specify the third point or more to copy the object/objects if you have. If you want to stop, use ESC
    • Please refer to this link for the copy command
    • Please practice Line, Move, Copy, and Rotate commands

    (CO8) Attach image/PDF/CAD and adjust the scale of the attached file
