Isometric projections

  1. 1. Isometric Projections Hareesha N G Dept of Aeronautical Engg Dayananda Sagar College of Engg Bangalore-78 01/28/14 Hareesha N G, DSCE, Bengaluru 1
  2. 2. ISOMETRIC DRAWING IT IS A TYPE OF PICTORIAL PROJECTION IN WHICH ALL THREE DIMENSIONS OF AN OBJECT ARE SHOWN IN ONE VIEW AND IF REQUIRED, THEIR ACTUAL SIZES CAN BE MEASURED DIRECTLY FROM IT. 3-D DRAWINGS CAN BE DRAWN IN NUMEROUS WAYS AS SHOWN BELOW. ALL THESE DRAWINGS MAY BE CALLED 3-DIMENSIONAL DRAWINGS, OR PHOTOGRAPHIC OR PICTORIAL DRAWINGS. HERE NO SPECIFIC RELATION AMONG H, L & D AXES IS MENTAINED. TYPICAL CONDITION. IN THIS 3-D DRAWING OF AN OBJECT, ALL THREE DIMENSIONAL AXES ARE MENTAINED AT EQUAL INCLINATIONS WITH EACH OTHER.( 1200) NOW OBSERVE BELOW GIVEN DRAWINGS. ONE CAN NOTE SPECIFIC INCLINATION AMONG H, L & D AXES. ISO MEANS SAME, SIMILAR OR EQUAL. HERE ONE CAN FIND EDUAL INCLINATION AMONG H, L & D AXES. EACH IS 1200 INCLINED WITH OTHER TWO. HENCE IT IS CALLED ISOMETRIC DRAWING L H 01/28/14 H H Hareesha N G, DSCE, Bengaluru 2 PURPOSE OF ISOMETRIC DRAWING IS TO UNDERSTAND OVERALL SHAPE, SIZE & APPEARANCE OF AN OBJECT PRIOR TO IT’S PRODUCTION.
  3. 3. SOME IMPORTANT TERMS: ISOMETRIC AXES, LINES AND PLANES: The three lines AL, AD and AH, meeting at point A and making 1200 angles with each other are termed Isometric Axes. The lines parallel to these axes are called Isometric Lines. A The planes representing the faces of of the cube as well as other planes parallel to these planes are called Isometric Planes. ISOMETRIC SCALE: When one holds the object in such a way that all three dimensions are visible then in the process all dimensions become proportionally inclined to observer’s eye sight and hence appear apparent in lengths. H This reduction is 0.815 or 9 / 11 ( approx.) It forms a reducing scale which Is used to draw isometric drawings and is called Isometric scale. In practice, while drawing isometric projection, it is necessary to convert true lengths into isometric lengths for measuring and marking the sizes. This is conveniently done by constructing an isometric scale as described on next page. 01/28/14 Hareesha N G, DSCE, Bengaluru 3

From point A, with line AB draw 30 0 and 450 inclined lines AC & AD resp on AD. Mark divisions of true length and from each division-point draw vertical lines upto AC line. The divisions thus obtained on AC 4 give lengths on isometric scale.
  5. 5. 1 AS THESE ALL ARE 2-D FIGURES WE REQUIRE ONLY TWO ISOMETRIC AXES. D H RECTANGLE A D D L A L C D C A B C B B B IF THE FIGURE IS FRONT VIEW, H & L 1 AXES ARE REQUIRED. H TRIANGLE B IF THE FIGURE IS TOP VIEW, D & L AXES ARE REQUIRED. 2 Shapes containing Inclined lines should be enclosed in a rectangle as shown. Then first draw isom. of that rectangle and then inscribe that 01/28/14 shape as it is. Isometric view if the Shape is F.V. or T.V.
