Rule category: Placement

Rule classification: Unary


This rule defines height restrictions for components placed within the design.


Default constraints for the Height rule.

  • Minimum – the value for the minimum permissible component height.
  • Preferred – the value for the preferred component height.
  • Maximum – the value for the maximum permissible component height.

How Duplicate Rule Contentions are Resolved

All rules are resolved by the priority setting. The system goes through the rules from highest to lowest priority and picks the first one whose scope matches the object(s) being checked.

Rule Application

The Preferred setting is obeyed when displaying the board in 3D. The Minimum and Maximum settings are obeyed by the Online DRC and Batch DRC.


  1. The height property for a component is defined in its associated properties dialog.
  2. Alternatively, the height is taken from the highest 3D body object included in the component footprint.
