Steps Involved in Isometric Drawing

Below are steps involved in isometric drawing:

Step 1: Draw with set squares; place the set square and make sure that both the face and side are inclined at 30° to the horizontal plane.

Step 2: Draw the isometric box that contains the object first. The box must have the overall size of the length, breadth and width of the desired object. (Note that this must be drawn with very thin lines).

Step 3: Draw the desired shape with faint lines inside the box using the correct dimension.

Step 4: Draw the correct shape of the object with a thick continuous line (i.e. outline.)

Step 5: You may rub off the construction lines or you may not if they are very neat and faint.

Activity:

To make an isometric drawing of a rectangular block of size 6cm by 4 cm by 1.5cm.

a. Construct the three axes with set squares, that is, one vertical line and two inclined lines at 30° to the horizontal in opposite directions.

b. Mark off on these axes length AB 6cm, width AC 4cm, and height AD 1.5cm.

c. Erect vertical lines at points B and C. (BE and CF)
