How to Draw a Spiral in PowerPoint
PowerPoint offers Shape tools that can help you create almost any shape. To draw a spiral in PowerPoint, all it takes is some knowledge and a bit of creativity. To get a perfect spiral, you’re going to need to combine arcs.
For starters, either open a blank PowerPoint presentation or add a blank slide to an existing presentation. Starting from scratch (from a blank file) will make things easier for you, so it is recommended that you delete the empty text boxes too. Now that all the clutter is out of the way, let’s get started.
Create an Arc
As mentioned, the main shape that you’re going to be using here is the arc. Go to the Insert menu. Now, select Shapes. In the drop-down menu, select the Arc icon. To draw the first arc, drag your mouse cursor across the screen. You don’t have to pay attention to its size at this moment. Once drawn, right-click on the arc and then click the Outline icon from the menu. This will allow you to select the line weight and color.
Draw a Line
Go to the Shapes menu again by selecting Insert. Now, find the Line icon and select it. Below the arc you’ve just drawn, draw a horizontal line. Hold down the Shift key while drawing the line. After the line is drawn, select the arc and use the Yellow Handles to drag the arc onto the line.
Go to Format in the Shape Tools menu. Now, select Size and expand the bottom of the menu by clicking the Expand Arrow. You need to set the Height and Width of the arc to 1”. This will turn the arc into a perfect semicircle. Keep in mind that the ends need to be exactly on the horizontal line. Additionally, the 1” is just an example. If you want to draw a smaller or bigger spiral, you can set the Height and Width accordingly.
Creating More Arcs
Let’s move on to the next step. First, you need to copy the arc. As you might know, this can be done by selecting it and pressing Ctrl + C to copy followed by Ctrl + V to paste it. Since the new arc has to be larger than the original, click on it and go to the Size menu. From there, set its Width and Height to double the size of the original spiral (or 2” for this example).
Now, press Ctrl + V again to create another arc. Follow the familiar steps to set its Width and Height to 3”. Create a fourth and final arc and set its size to 4”. After that, position all of the arcs so that they are equally spaced and centered on the original (smallest) arc, making sure that they’re touching the horizontal line.
Creating the Spiral
First of all, delete the horizontal line because you won’t need it anymore. Now, hit select all by pressing Ctrl + A to select all the arcs. Copy and paste them with the Ctrl + C and Ctrl + V commands. Now, select the new group by clicking and dragging. Use the Rotate Handle near the selected group of arcs and rotate 180 degrees while holding down the Shift key.
Now, drag the “inverted” copies to the left or right by 1” (for this example) until the edges of the arcs touch perfectly. And there you go, you now have an interwoven double-spiral!
To make a single-spiral, you need to find the outer spiral’s 10 o’clock, Ctrl-click it, and Ctrl-click every other spiral at 10 o’clock (diagonally). Now, hit the Delete key to delete the surplus arcs and you’ll have your single-spiral arc.
This is where you can get creative and use the spirals to create interesting effects. For one, you can create a copy of the spiral, decrease the copy in size, and put it below or above the original arc. Do this a few more times and you’ll get a cool 3D-like effect.
Another cool thing to try is to move one arc after rotating it an additional inch. How do you find this spiral effect?
Now that you know how to draw a spiral in PowerPoint, use this to experiment with interesting ideas for whatever purpose. Perhaps one to represent the effects of magic mushroom and one to create attention-grabbing presentations.
