  1. 1. ES1 PLATE NO. Edge View Drawing Shape of Planes Isometric and True ISOMETRIC DRAWING  An isometric drawing or isometric sketch is a drawing using the full length measurement of the actual object. However, in our case, the length of the multiview projection of the object.SECTION: THQR / THWX2 NAME: JUAN FIDEL B. CALAYWAN SECTION: THRU2 NAME: MIKHAEL ANTHONY A. FELIPE GRADE: 17.1 GRADE: 10.0 1

  4. 4. ES1 PLATE NO. Edge View Drawing Shape of Planes Isometric and True STEPS IN MAKING AN ISOMETRIC DRAWING OF NORMAL SURFACES  Rectangular objects are easy to draw using glass box construction, which consists of imagining the object enclosed in a rectangular box whose sides coincide with the main faces of the object.  Lightly draw the overall dimensions of the glass box. 30° 30°  The edges of the box should all measure equal angles with each other. In other words, the base edge of the box should make 30° from the normal.SECTION: THQR / THWX2 NAME: JUAN FIDEL B. CALAYWAN SECTION: THRU2 NAME: MIKHAEL ANTHONY A. FELIPE GRADE: 17.1 GRADE: 10.0 4
