Why is it important to draw bounding boxes lightly (e.g., in orange) at the beginning of an orthographic projection?

They might need to be erased later.

When drawing normal surfaces (horizontal and vertical), what is the recommended order for drawing visible and hidden faces?

Draw all the visible faces first and then the hidden faces afterwards.

I can create orthographic projections of three-dimensional objects.

1
The first step in orthographic projection is to draw bounding boxes to ensure all views fit on the page.
2
When all surfaces are normal (horizontal and vertical), draw the visible faces first, then the hidden faces.
3
Hidden surfaces are indicated by hidden lines, which should meet at a dash where horizontal and vertical lines connect.
