Spacing Vertical or Horizontal Elements

DML is short for Diagonal Measuring Line. Note: terms use on this page may not be universal.

The images on this page require a subscription to either Basic or YoungMinds.

This picture is an example of how to space vertical objects such as posts, poles. Study the picture to figure out how it is done. This also applies to horizontal elements that are evenly spaced.

See Animation

This is based on this one simple fact.

An X drawn corner to corner inside a square, rectangle, or circle will show you where the center is and this will allow you to draw things that are regularly spaced such as tiles in floors, railroad tracks, and telephone poles, and so forth.

Consider this idea with a grid.

This image shows a model of squares with a diagonal line drawn through the corners. Take note of what we normally take for granted... the diagonal line crosses through the intersections of the squares.

Look at the foreshortened model of the squares. Notice that the diagonal measuring line (DML) crosses through the intersections in the same way.

Consider how understanding this simple fact this will help you draw in perspective. For instance, the drawing below is possible with the diagonal measuring line.

Go to: 1-Point Grid for steps in drawing a gridded plane with one-point perspective

The grid on the ground line (GL) or horizontal measuring line (HML) determines the spacing of the parallel lines that meet at the vanishing point. (The lines going toward the vanishing point are parallel.. They don't look parallel do they? In real life they would be.)

The DML determines where the horizontal lines will be drawn. Notice in the image where the BLUE DML intersects with the parallel lines (circled in yellow in the image to the left.) The intersection of the DML with the parallel lines is where to draw the horizontal lines. (Remember the grid?)

Now it is just a matter of precise drawing.

2-Point Perspective Models

I'm sorry that I do not have time to write about these drawings. I'm going to drop them here and perhaps just observing where the SVP are in relation to the location of other points will be self-explanatory on the effects of the gridded plane.

Circles

The DML (diagonal measuring line) will help you make circles too. Look at the image above. I have drawn a square and then I marked the square with two DML's making an x in the square. Next each DML half was divided into thirds.. that is what the tick-marks are on the lines. Next a circle was drawn using the tick marks and the square's 4 sides. Notice one thing... The circle is just beyond the tick marks; it is not on the tick mark.

Now take this idea into a cube. See image belowCarefully look at the tick marks in this foreshortened cube. Note that the tick marks furthest away are closer to the circle. Always keep in mind that you are drawing in perspective and the parts of the drawing which are "further away" become closer to each other and smaller and thinner.

It takes some practice to be able to do this well, so don't give up if it seems difficult.

Perspective books:
I have all of the books linked below and my ungiven opinion varies on each of the books.
(Links last checked August 2, 2011)

Elementary: Lessons in Perspective Drawing published by Rod and Staff
Links: Lessons in Perspective Drawing or Lessons in Perspective Drawing (links go to same book)

7th - High School: Lifepacs Elective Art Unit 4 (You do not need the teacher's book for this one course in my opinion)

Advanced: The Art of Teaching Art by D. Rockman. Heads-up- This is an art book, so of course there are nudes in it and a few deserve to be covered. This can be accomplished with small post-it notes. Covering the nudes does not hamper the quality of the book. You may preview the book at books.google.com and at amazon.com. This book is useful for teaching upper level art classes.
Also check your library and the internet for resources.
