Steps to create a drawing
1. Sketch the multiview from the isometric
view and locate the views on the drawing
sheet
2. Draw a light construction of view
Starting from Front view Æ Top viewÆ
Side view
3. Line in progressively working down and
across the page by using a set square.
4. Dimension and insert subtitle & notes
