Transcript of 3D Drawing

3D Drawing Isometric Projection Isometric projection is a drawing technique. It is fairly realistic and normally used to represent 3D objects.
Main advantages are that you can draw a 3 dimensional object directly to scale.

Exploded Drawings Exploded drawings are used to show how an object fits together, component by component.
It is quicker than drawing in perspective and therefore designer and architects use this method.
Isometric projection is a drawing technique. It is fairly realistic and normally used to represent 3D objects. Drawing Circles Circles in isometric appear as ellipses
Using an ellipse template is the easiest way to draw them
Although it is not that hard to produce them freehand

1 Point Perspective Perspective is how we usually see an object. The furthest point of an object is foreshortened. The smaller it seems to be the further away it is. Horizon Line
The horizon line splits the sky from the ground and is always at eye level Vanishing Point
It is positioned on the horizon line and is the point where all the lines meet and seemingly vanish, except for the horizontal and vertical ones. A perspective with one vanishing point can be used for quick perspective sketching.
2 Point Perspective One point perspective gives a flat perspective whereas 2 point perspective gives a realistic view point.
There are 2 vanishing points labelled left and right

The way we look at an object depends on where it is in conjuction with eye level View Point in 2 point perspective Drawing an object in 2 point perspective..... 1 Draw horizon line with 2 vanishing points. Split line into 3 (indicating the front, bottom corner) Draw 2 lines from front corner point back to vanishing points 1 and 2.
2 3 Mark a point on the height line showing the height of your object, draw 2 lines back to the vanishing points
This is an example of a circle in isometric 4 Mark the width and depth + draw in other vertical lines
From this, draw line back to opposite VP: to complete 5 Draw the side view onto one of the workplanes & draw in constrcution line to Vanishing Point 1 6 Complete the side view on the opposite workplane, using these latest lines as a guide 7 Join both workplanes together to show the object in 2 point perspective.
