Contour Line | Blind Contour

The simplest and earliest method of drawing was “Delineation”. Its most pure form is the Contour Line.

Three major types of Contours:

  1. Blind Contour
  2. Negative/Positive Contour
  3. Cross Contour

This is the line demarcating of “What is” and “What is not”. It is a boundary between what is perceived – seen – called. The positive shapes, and the space surrounding the perceived object called the “Negative shape”.

The contour line is a deceptively difficult line to draw well and a well drawn contour line rests upon sensitive and detailed persuasive information.

It is a line which has not only to express the edges of the figure but also suggest what conceals behind it.

This exercise has to make use of line in all its possibilities:

  • Even and Variable
  • Thick/Thin
  • Light/Dark

Line Exercises | Understanding the importance of Line weights

In my previous article, we discussed how important the line weights are. Now we will go ahead with necessary Line Exercises.

Line Exercises is the first lesson to learn in Architecture. It helps you understand the importance of every stroke drawn by you. It helps you realize that every stroke that you draw should convey a meaning in terms of design.

Here are a few things you need to do before you proceed with “Line Exercises”.

  1. Pencils – HB/B/2B
  2. Drawing Sheet – 22″x30″
  3. Draw 1/2″ border lines with title block of width 2″
  4. Divide the drawing sheet into 9 parts

After you are successfully done with the first line exercise, we will proceed to the next line Exercise with more complex patterns.

Motor/Visual Coordination

A line is a meeting of two points through a stroke.

The ease of drawing a line and its length differs with respect to :

  1. Finger Movement
  2. Wrist Movement
  3. Elbow Movement

Lines drawn by the movement of finger, Wrist and Elbow respectively
Lines drawn by the movement of finger, Wrist and Elbow respectively

A line has to be drawn with one stroke with the beginning and ends emphasized.

Types of Strokes

  1. Thin/Thick
  2. Light to Dark
  3. Dark/Light/Dark
  4. Light/Dark/Light
  5. With Varied Pressure

Layout of a Typical Drawing sheet and method of Dimensioning

Example of the Layout of a Typical Drawing Sheet | Architectural Drawing

In this article, we will illustrate the layout pattern of a drawing sheet which should be adopted by an Architect or an Engineer. The systematic layout helps the client understand the drawing in a better way. Also, the masons and the Contractors are dependent on the drawings prepared by the Architects and Engineers. The clarity in drawings and systematic approach helps to keep the matters under control and prevents complexities.

Dimensioning of the Drawings

Purpose of the dimensioning of the drawings

The drawings are detailed dimensioned for the purpose of accurate execution. The dimensioning has to be done in three layers.

  1. First layer(line) of dimensioning would include every single and smaller dimensions
  2. Second layer(line) would consist of dimensioning of two or more dimensions together for easy understanding
  3. Third layer(line) would consist of dimensioning of the entire length
