Import Clearance Rules Automatically into the Clearance Matrix

When importing clearance rules from schematic design directives or migrating projects from the legacy design rules dialog, clearance rules are now placed in the Clearance Matrix within the Constraint Manager, rather than being assigned to the Advanced Rules section.

Gain More Control Over Your Harness Design Settings

You now have more control over harness design settings. A new preference lets you set the default blank sheet size for wiring diagrams and layout drawings. Length units have been standardized and can be customized at different levels, including preferences, documents, and tables like BOMs and connection lists. You can also filter connection tables to show only 'no connect' objects. Additionally, a fix ensures that specified units now apply correctly to all wires, including those not part of a cable.

3D Automatic Face Filling

3D Automatic Face Filling automatically generates a geometric pattern to fill a face of a substrate in 3D-MID designs, based on selected tracks. It creates a patterned covering that extends perpendicular to the track, adapting to surface boundaries and avoiding obstacles. This provides a faster and more efficient way to create protective meshes for security purposes, such as in secure payment terminals, without the need for manual routing.
