How to Draw 3D Solids
In this section you will learn the basics of how to draw 3D shapes, as well as the tecnhiques to facilitate the learning process.
Orthographic projection
Vanishing point
Isometric dot paper
Perspective Drawing
Isometric Dot paper is a style of graph used for the correct and proportional representation of 3D figures and solid geometric shapes.
This certain type of paper uses filled in points, unlike a common graph that uses lines that close up to make squares. The dots facilitate and improve precision.
A perspective drawing is a technique used when drawing 2D shapes and making them appear 3D.
Basically you use a sense of linear perspective in order to make the shape appear more realistic.
Orthographic projection is also a tecnhique used to draw Solid Figures.
Usually on isometric dot paper, this method included drawing 3D shapes in various perspectives and views, mapping out the figure using mostly parallel lines.
A vanishing point, in terms of drawing 3D figures, is the point in which the extension of the parallel lines that have created the drawing come/group together.
Sometimes this vanaishing point is not present visually in the drawing, but should be able to be drawn at any time when extending the lines of the drawing.
