The Align Objects dialog

Summary

The Align Objects dialog provides controls for quickly aligning the set of currently selected objects.

Access

With the objects to be aligned selected, the dialog can be accessed in the following ways:

  • From the PCB Editor or PCB Library Editor:
    • Click Edit » Align » Align from the main menus
    • Right-click in the workspace then choose the Align » Align command from the context menu
  • From the PCB Editor, click the Align Components button () on the Alignment Tools drop-down () of the Utilities toolbar.

Options/Controls

  • Horizontal - choose from one of the following options to determine the horizontal alignment of the selected objects:
    • No Change - leave the horizontal alignment of the objects unchanged.
    • Left - align objects so the outer edge of their left-most primitives have the same X location. The object with the left-most primitive is used as the reference.
    • Center - move objects horizontally so their centers are aligned. After clicking OK, you are prompted to click to choose the reference object.
    • Right - align objects so the outer edge of their right-most primitives have the same X location. The object with the right-most primitive is used as the reference.
    • Space equally - objects are equally spaced in the horizontally direction, between the left-most and right-most objects (which do not move).
  • Vertical - choose from one of the following options to determine the vertical alignment of the selected objects:
    • No Change - leave the vertical alignment of the selected objects unchanged.
    • Top - align objects so the outer edge of their upper-most primitives have the same Y location. The object with the upper-most primitive is used as the reference.
    • Center - move objects vertically so their centers are aligned. After clicking OK, you are prompted to click to choose the reference object.
    • Bottom - align objects so the outer edge of their lower-most primitives have the same Y location. The object with the lower-most primitive is used as the reference.
    • Space equally - objects are equally spaced apart in the vertical direction, between the upper-most and lower-most objects (which do not move).
Enabling both Horizontal and Vertical options at the same time may result in a conflict, with the selected objects becoming stacked on top of one another.
Using the Space equally options can result in the moving objects being off-grid.
