Scale, or depicting objects and spaces at a specific ratio to their actual size, is a critical to precise manual drafting techniques. Lesson Summary. Basic algorithms rasterize lines in one color. Technical drawing Lines are used for different purposes to provide specific information for designers, manufacturers, etc. Drafting students or those reading the drawings have to learn what they mean, just as one learns a new language.

The drawing implement stays in uninterruped contact with the surface of the paper during the entire length of the drawing. A line drawing algorithm is a graphical algorithm for approximating a line segment on discrete graphical media. 15 Basic Drawing Techniques for Beginners. Drawing techniques. Different line weights can be created by using a different size mechanical pencil lead, or a different size of technical drawing pen. Continuous line drawings are made by keeping the pen or pencil in contact with the paper for the duration of the exercise, and by matching speed of looking with speed of drawing. If you’re really look for a challenge when it comes to realistic drawing and reflections, then check out how Circle Line Art School suggests drawing a glass of water.
