If you have ever looked at a set of construction drawings, you may have noticed that a large portion of the drawings are section cuts and detail drawings. Inside each of these are architectural poche patterns. This article will teach you how to draw the most common poche patterns by hand.

Drawing Earthwork Poche Patterns

  1. 1
    Choose the size of your drawing. Poche patterns do not have a scale. They are purely a visual representation of materials. However, poche patterns should communicate the material, while representing the projected size of materials.
  2. Earthwork poche patterns only go where the earth is. The most common place you may need them is when you poche a section cut that may include part of the structure that is below the surface of the Earth.

  3. This square should be equivalent to about two feet tall and wide depending on the scale of the drawing. This square does not need to be exact, but you should be able to fit at least four of the squares into the desired area. The more squares you can fit the better.
  4. Draw two vertical lines with the help of a triangle. These two lines should be dark.
  5. The square should be the same size as the initial square. Draw this square above, below, or laterally from the initial square.
  6. The lines of this square should be horizontal, use a triangle to help keep them straight. Ensure that these lines are dark.
  7. The squares should alternate in the vertical and horizontal plane between vertical thirds and horizontal thirds.

Drawing Wall Poche Patterns

  1. Walls are often drawn with the darkest lines on the floor plan. The wall cavity is what will be poched.
  2. Use a 6B pencil for the best results, but any pencil will work. Ensure the color is even throughout the cavity. Avoid over filling because it can make the fill seem shiny.Walls are poched with a solid black because most often they are above what is called the cut line. The cut line is where the structure is “cut” to see the floorplan. The darker the line, the closer to the cut plane the structure is.
  3. Fill each wall cavity with the solid dark color. Ensure the shade is congruent throughout the entire structure.

Drawing Structural Steel Poche Patterns

  1. Most often structural steel won’t be poched unless looking at a detail drawing. On a floor plan it will most likely be filled with a solid dark color.
  2. These lines should span across the entire structure. If the line meets the edge of the structure, but the lines would meet the structure again continue the line, but make sure to only poche the structure.
  3. Double the spacing between the initial two lines and start the new set of lines there.
  4. Continue the process again until the entire desired structure has been filled with the poche pattern. This may take some time to do by hand. The lines do not need to be exactly the same distance apart every time. Remember poche patterns are only a visual representation of the material and not something that needs to be super precise.

Drawing Masonry Poche Patterns in Elevation Drawings

  1. 1
    Identify the type of drawing for the poche pattern. There are different techniques that depend on the type of drawing.
  2. The scale is important for drawing masonry because masonry units have a specific height and width.
  3. The height of the masonry unit is all that is necessary for the elevation poche pattern.
  4. Decide what area of the drawing needs to be poched. Identification of the area of work is important to not accidentally poche the wrong piece of the structure.
  5. Once the scale and the height of the masonry unit have been determined use the scale to mark where the rows of masonry units will be placed.
  6. Use a triangle or a parallel to draw perfectly horizontal lines across the area that you desire to poche. These lines represent the mortar joints between each masonry unit.

  1. The scale is important for drawing masonry because masonry units have a specific height and width.
  2. The height and width of the masonry unit will be important because each unit will need to be illustrated.
  3. Decide what area of the drawing needs to be poched. Identification of the area of work is important to not accidentally poche the wrong piece of the structure.
  4. By marking the height and the width along the edge of the desired area it will provide you with guidelines to use when placing the mortar joints.
  5. Use a triangle or a parallel to draw horizontal lines perfectly across the desired area at each of the marks along the vertical axis of the desired area.
  6. Use a triangle to help draw vertical lines at each of the tick marks. You must skip a horizontal row for each vertical line. Ensure that the vertical lines are offset halfway between the other vertical mortar joints.

      Tips

      • Read architectural drawings from different firms with poche patterns. Exposure to different designs and conventions will enhance your proficiency in interpreting these drawings accurately.
      • The thickness and shade of each line is important to keep in mind when drawing poche patterns. Things that are farther away appear lighter on the drawing compared to pieces of the structure closer to the point of view.
      • Patience is key when drawing poche patterns. Poche patterns can be time consuming to create by hand. Being patient and paying attention to detail will help keep your poche patterns consistent.
