Are you staring crossed-eyed at a screen wondering how to flip or rotate a selection in your design? Well, look no further, because flipping and rotating a selection in PaintTool SAI is easy! All you need is to open your program, and a few minutes to spare. 

My name is Elianna. I have a Bachelor of Fine Arts in Illustration and have been using PaintTool SAI for over 7 years. I’ve done it all in PaintTool SAI: flip, rotate, transform, merge…you name it. 

In this post, I will show you how to flip or rotate a selection in PaintTool SAI. I will give you step-by-step instructions on how to make it happen, using the layer menu or some simple keyboard shortcuts.  

Let’s get into it! 

Key Takeaways

  • Use Ctrl + A to select all of the pixels in a layer. 
  • Use Ctrl + T to transform the pixels into a layer. 
  • Use Ctrl + D to deselect a selection. 
  • Pin layers together to flip or rotate them at the same time. 
  • If you would like to flip or rotate all of the pixels on your canvas instead of individual layers, look at the options in Canvas the at top menu bar. 

Method 1: Flip or Rotate a Selection Using the Layer Menu

An easy way to flip or rotate a selection in PaintTool SAI is using the options in the layer panel. You can use this method to flip or rotate your layers in PaintTool SAI with ease. Before we start, here is a breakdown of the four selection transform options in SAI: 

  • Reverse Horizontal – Rotates your selection on a horizontal axis
  • Reverse Vertical – Rotates your selection on a vertical axis
  • Rotate 90deg.CCW – Rotates your selection 90 degrees Counterclockwise 
  • Rotate 90deg. CW – Rotates your selection 90 degrees clockwise 

Quick Note: If you would like to flip or rotate more than one layer simultaneously, pin them together first with the pin tool. This will ensure that your edits occur at the same time. 

If you would like to flip or rotate all of the pixels in your canvas, skip to method 3 in this post. 

Now follow these steps: 

Step 1: Open your document.

Step 2: Select the layer you would like to flip or rotate.  

Step 3: Using the selection tools, select which part of the layer you would like to transform. If you would like to select all of the pixels in your target layer, simply hold down Ctrl + A (select all). 

Step 4: Click Layer in the top menu. 

Step 5: Click which option to rotate or flip your selection as preferred. For this example, I am using Reverse Layer Horizontal.

Step 6: Use the Keyboard Shortcut Ctrl + D to deselect your selection. 

Method 2: Flip or Rotate a Selection Using Ctrl + T

Another method to easily flip or rotate a selection in PaintTool SAI is using the Transform keyboard shortcut Ctrl+T. 

Step 1: Open your document in PaintTool SAI.

Step 2: Using the selection tools, select which part of the layer you would like to transform. If you would like to select all of the pixels in your target layer, simply hold down Ctrl + A (select all). 

Step 3: Hold down Ctrl + T (Transform) to bring up the transform dialog menu. 

Step 4: Select an option to rotate or flip your selection as desired. For this example, I am choosing Reverse Horizontal

Step 5: Hit Enter on your keyboard and that’s it. 

Method 3: Flip or Rotate Canvas Using Canvas Options

You don’t need to flip or rotate every layer in your canvas separately. You can easily flip or rotate all of your layers at one time using the options in the Canvas menu. Here is how. 

Step 1: Open your canvas. 

Step 2: Click on Canvas in the top menu bar. 

Step 3: Click on which option you would prefer to edit your canvas. For this example, I am selecting Reverse Canvas Horizontal

Enjoy!
