Designing Presentation & Research Posters with Illustrator

You may want to use simple shapes and lines in Illustrator to create your poster. The shape tool (#4 in our illustration on the left) holds several shapes. You get to those other shapes by clicking and holding on it until a menu of shapes appears.

Rectangles and Squares

1. Click and hold on the shape tool (tool #4 in our illustration), and select the Rectangle shape.
2. Do one of the following:
   1. To draw a rectangle, drag diagonally until the rectangle is the desired size.
   2. To draw a square, hold down the Shift key while you drag diagonally until the square is the desired size.

   Ellipses and Circles

   1. Click and hold on the shape tool (tool #4 in our illustration), and select the Ellipse.
   2. Do one of the following:
      1. Drag diagonally until the ellipse is the desired size.
      2. Click where you want the top-left corner of the ellipse’s bounding box to be. Specify a width and height for the ellipse, and click OK.

      Note: To create a circle, hold down the Shift key while dragging, or if you are specifying dimensions, once you’ve entered a Width value you can click on the word Height to copy that value into the Height box.

      Polygons and Triangles

      1. Click and hold on the shape tool (tool #4 in our illustration), and select the Polygon shape.
      2. Do one of the following:
         1. Drag until the polygon is the desired size. Drag the pointer in an arc to rotate the polygon. Press the Up Arrow and Down Arrow keys to add and remove sides from the polygon.
         2. Click where you want the center of the polygon to be. Specify a radius and number of sides for the polygon, and click OK.

         Triangles are polygons too! You can draw one just as you would any other polygon.

         Stars

         4. Click where you want the center of the star to be. For Radius 1, specify the distance from the center of the star to the star’s innermost points. For Radius 2, specify the distance from the center of the star to the star’s outermost points. For Points, specify how many points you want the star to have. Then click OK. To increase or decrease the number of points in the star, you can also use the up and down arrow keys while drawing the star.
