How do I add a custom/fixed alignment guide in Pixelmator? I know it's possible because I done it before and I'm working with a file that already has three, but I need to add one more. How is that done?

This is the procedure:

  1. Select View > Show Rulers.
  2. Do one of the following:
    • Click and drag any of the horizontal or vertical ruler bars and drop the guideline anywhere onto your image.
    • Double-click the horizontal or vertical ruler bars and choose New guide from the shortcut menu in order to open a Place a Guide sheet. Select a horizontal or vertical orientation and enter a position at which the guide should be placed. Click OK after you are done.
    • Hold down the Option key as you drag away from the vertical ruler in order to create a horizontal guide and vice versa.

Tip: Hold down the Shift key as you drag a guide to make it snap to the ruler ticks.


To the best of my knowledge the PXM Version 3.3.2 Limestone (50417) cannot create custom guides, but only regular straight ones.

My way to use any object as a guide is a relatively new feature "Lock layer" - I create thin lines/objects and lock them, thus they are used as a guides:

The horizontal line is a regular guide of pxm, the diagonal - straight lines locked and used as custom guides.
