How to Draw Fan-shape Pavements
Fan-shaped tiles are often seen on parks, in combination to setts and cobbles. Drawing it could be a bit tricky since these are curved quarter of circles made of square tiles. The trick is to understand the layout.The evenness of each fan shape can be made by starting with circles rowed properly.
Basically, the quarter half of a circle should be overlapped by the quarter halves of the other circles.
- Divide the area into three rows (or more, depending on the number of fans you will make).
- Make a row of circles. Find the center (of the circles) and make a reference line.
- The second row of circles will start from below or above the reference line you made (the center line of the first row of circles), and then mark a reference line on the lower half of the first row. (the upper half of the second row) This will be the center of the third row of the circles that will alternate the column of the first and second row. This reference line can be located easily by marking an ‘X’ on the columns created by the reference line (center line) of the first and second row. The intersections of the ‘X’s would be the center of the circles’ halves.
- Create another column of circles from the alternating row (third row of circles). And again, find the center of the upper half of the first column (this should be the top of the third row of circles).
- With the last reference line you made, make two rows of circles above and below it.
- With those set of circles, you can find the fan shape at the upper division of each circles created by the other two circles overlapping it. Mark these fan shapes with borders of cubes or tiles.
- Fill up each fan with tiles.
- Clean up the drawing. Now you have your fan shaped tiles.
To make a fan-shape tiles as a pavement, apply the same method with the reference lines following a vanishing point.
- Depending on the number of fans you want to make, divide the areas evenly. From these reference marks (indention of the evenly divided space), draw the vanishing lines going to a single vanishing point.
- Draw your first horizontal reference line. By this line, you now have your first row where you should place your first circle.
- Draw another set of vanishing lines coming from a vanishing point on a farther side of the horizon line. Use the intersections of your first and second sets of vanishing lines to find where the next horizontal reference lines should be. These intersections created by your vanishing lines will effectively adjust to the perspective of your plane.
- To establish the other rows on the farther part of the plane, draw diagonal lines coming at the sides of the other rows you previously made.
To know if you did the steps correctly, the vanishing lines coming at the far side of the horizon line (the ones you used to establish the first rows) and the diagonal lines that you made (to further establish the other rows) should have converged on the boxes and produce cross (X) reference lines establishing the center of each box.
