Question

what is a recommended first step when beginning to copy an isometric drawing onto graph paper?
draw the top - face of the object first as it receives more light.
apply the darkest shading to establish the objects form.
make a circle and then fill in the form.
pick a corner on the object as a starting point.

Explanation:

When copying an isometric drawing onto graph - paper, starting from a corner helps in accurately mapping out the object's dimensions and shape. The other options are not typical first - steps in isometric drawing. Drawing the top - face first due to light has no bearing on the accuracy of the isometric copy. Applying shading is a later step in the drawing process, not a first step. Making a circle and filling in the form is not relevant to isometric drawing.

Answer:

Pick a corner on the object as a starting point.
