What is a construction line?
It is very like an assembly line, where a product is assembled in chronological steps by many people.
When you construct a parallel to a line through a point not on the line using paper folding what construction can you perform twice?
What construction do you perform twice when you are constructing a parallel to a line through a point not on the line using paper folding?
To construct a parallel to a line through a point not on the line using paper folding you can perform the construction twice?
What if you repeat the perpendicular line segment construction twice using paper folding you can construct?
A construction lines are a lightly drawn lines that aid in drawing all other lines or shapes properly. An example of a construction line are those on a sheet of graph paper. These lines are lightly drawn and they help with the construction of shapes and figures. Construction lines are also useful in Multiview Drawings. They are projected from one figure and help the drawer make another figure. These lines are erased afterwards.
First, draw your horizon line across the top of the page. Mark two vanishing points, as far apart as possible. Draw a short vertical line for the front corner of your box and then draw a construction line from the top and bottom of the line, to each vanishing point. Next draw a vertical line to the left of your 'front corner', between the top and bottom construction lines. From the top and bottom points…
