Background Theory > Distributing Objects

Distributing objects in PCB design refers to the process of spacing multiple objects evenly along a specified axis, whether horizontally or vertically. Distributing objects ensures that they maintain a consistent and organized arrangement, which is crucial for achieving a professional and visually appealing PCB layout. Most Electronic Design Automation (EDA) software tools provide distribution features to help designers evenly space and align objects.

Here's how to distribute objects in PCB design:

•Select Objects: First, select the objects you want to distribute. These could be components, traces, pads, or any other elements you wish to space evenly.

•Access Distribution Feature: In your PCB design software, navigate to the menu or toolbar where the distribution features are located. These features might be named "Distribute," "Evenly Spaced," "Align and Distribute," or similar.

•Choose Distribution Axis: Specify whether you want to distribute the objects horizontally or vertically. Some tools might also offer options for distributing along both axes simultaneously.

•Select Distribution Type: Depending on the software, you may have options to distribute objects evenly between their outer edges, centers, or reference points.

•Execute Distribution: After selecting the desired distribution axis and type, execute the distribution command. The software will automatically adjust the spacing between the selected objects to achieve even distribution.

•Fine-Tune Spacing: Some tools allow you to fine-tune the spacing or alignment after distribution, ensuring that the arrangement suits your design requirements.

•Apply Distribute Vertically or Distribute Horizontally: Some software tools might provide separate commands for distributing objects along each axis. In this case, you would choose the appropriate command based on the alignment you need.

•Keyboard Shortcuts: DEX offers keyboard shortcuts to quickly access distribution features.

Distributing objects is especially useful when arranging components or traces in rows, columns, or grids. It helps maintain uniform spacing, which can improve the visual appearance of the layout and ensure that components are positioned within the required clearances.

When using the distribution feature, keep in mind any specific design constraints, such as minimum trace widths, component clearances, and signal integrity considerations. Distributing objects should contribute to an organized and optimized design while meeting all design requirements.
