1.4 Engineering Drawing

• 1.4.1 What is Engineering Drawings?
• Engineering drawing is a formal and precise way
  of communicating information about the shape,
  size, features and precision of physical objects.
• Drawing is the universal language of engineering
  that use to communicate with eng., technicians,
  etc.
• Its purpose is to accurately and unambiguously
  capture all the geometric features of a product
  or a component.

5
Definition ED AutoCAD

• A document that communicates a precise
  description of a part.
• Engineering drawings are legal documents, so they
  must be formal and precise.
• An engineering drawing is a type of drawing that
  is technical in nature, used to fully and clearly
  define requirements for engineered items, and is
  usually created in accordance with standardized
  conventions for layout, interpretation,
  appearance (such as typefaces and line styles),
  size, etc.
• The process of producing engineering drawings,
  and the skill of producing them, is often
  referred to as technical drawing, although
  technical drawings are also required for
  disciplines that would not ordinarily be thought
  of as parts of engineering.

1.4 Engineering Drawing (continued)

• 1.4.2 Engineering Drawing Standards
• The American National Standards Institute (ANSI)
• Units Inch
• International Organization for Standardization
  (ISO)
• Units milimeter(mm)

7
1.4 Engineering Drawing (continued)

• 1.4.3 Traditional Eng. Drawing Tools

8
1.4.4 Modern Eng. Drawing Tools

• Softwares. Why Use Softwares?
• Paperless
• Easy Handling
• User-friendly command
• More precise
• Common software used for engineering drawing
  AUTOCAD, ASPENTECH, VISIO, SOLID WORKS.

9
What is engineering graphic?

• Graphics Refers to any computer device or program
  that makes a computer capable of displaying and
  manipulating pictures.
• Use latest software to design engineering objects
  and flowsheets.

10
Basic Information Included in a Drawing

• Projected Views Show as many sides as needed
  for completeness.
• Cross Sections A view that is good for showing
  interior features.
• Table Lower right corner, with material
  information, part name, designer etc
• DIMENSIONS!!! These are the most important and
  most complicated part of the drawing. There is
  more to it than just the numerical values!

Dimensions

• Dimensions tell how far it is from one point on
  an object to another point.  The most basic type
  is called a Linear Dimension because it gives the
  straight-line distance from one point to
  another.  There are also Radial, Diameter and
  Angular Dimensions.
• Dimensions have four basic components
• Dimension Text
• Dimension Line and Arrows
• Extension Lines
• Gap

Scaling

• Scaling is used to depict objects on paper that
  are either larger or smaller than the paper.
• If the object is larger than the paper, then the
  views of the object are scaled Down
• If the object is smaller than the paper, then the
  views of the object are scaled Up
• If the object fits on the paper, then the views
  are depicted at Full scale  (11)

17
Definition of Simulations

• process simulation is the action that executes
  all necessary calculations needed to solve the
  outcome of the system, hence predicting its
  behavior
• Examples of common simulator Design II,
  SuperPro, ChemCAD, Hysis, MATLAB,

18
Introduction to ASPEN PLUS

• ASPEN PLUSTM allows you to create your own
  process model, starting with the flowsheet, then
  specifying the chemical components and operating
  conditions.
• ASPEN PLUSTM will take all of your specifications
  and, with a click of the mouse button, simulate
  the model.
• ASPEN PLUSTM lists the results, stream by stream
  and unit by unit, so you can observe what
  happened to the chemical species of your process
  model

19
ASPEN PLUS outcomes

• Become familiar with the Aspen Plus graphical
  user interface
• Enter basic input required for a simulation
• Review major unit operation models, such as flash
  drums, heaters, reactors and columns discuss
  flowsheet handling
• To learn the basic concepts required to model and
  analyze steady-state processes using Aspen Plus
