ISOMETRIC DRAWING

ISOMETRIC DRAWING

MAPUA – DEPARTMENT OF MULTIMEDIA ARTS AND SCIENCES

Is a form of pictorial drawing used to make a three—view drawing easier to visualize.

It is made with a 30 X 60 degree triangle.

An isometric is actually a three dimensional drawing because the height, width and the depth are all drawn on a single plane.

ISOMETRIC CIRCLES AND ARCSISOMETRIC CIRCLES AND ARCS

The procedure for drawing the isometric circle using the four—center approximate method.

STEP 1 Draw the isometric square whose sides are equal to

the diameter of the circle.

STEP 5Locate the centers of minor arcs. The centers of minor arcs can be located by connecting the centers of the major arcs to the midpoint of their opposite sides, the intersections of these lines are the centers of the minor arcs which are points E & F.
