orthographic views with its engineering dimensions
●CO2. Draw sketches of shipboard machinery parts diagram
applying the basic concepts of technical drawing.
Competence:
• Maintenance and repair of shipboard machinery and equipment
3. At the end of the discussion the students shall be able to:
Learning Outcomes:
●Draw solids in isometric projection
●Draw sample shipboard component in isometric projection
applying necessary line work
5. Isometric Projection
Terms
Isometric
The term "isometric" comes from the Greek for "equal
measure", reflecting that the scale along each axis of the
projection is the same.
Isometric view
An isometric view of an object can be obtained by choosing
the viewing direction such that the angles between the projections
of the x, y, and z axes are all the same, or 120°.
6. WHAT IS AN ISOMETRIC PROJECTION?
Isometric projection is a method for visually representing
three-dimensional objects in technical and engineering drawings.
It is an axonometric projection in which the three coordinate axes
appear equally foreshortened and the angle between any two of
them is 120 degrees.
Isometric Projection
10. Procedure in Drawing Isometric Projection
1. Draw the isometric axis
2. Construct an isometric box
3. Draw the irregular features relative to the sides of the box
4. Darken the final lines (border lines)
Isometric Projection
12. Isometric Projection
In constructing the isometric box used the
dimension of your object.
○ Width of the front view and side view
○ Longest height of the object
