Underlying Altium Designer's schematic and PCB editors is a powerful query engine. By entering queries into this engine, you can logically scope precisely those objects you require. A query is a string you enter using specific keywords and syntax, which will return the targeted objects. There are a number of places where you can apply a query but command central is the Filter panels shown in the…

The Membership Checks PCB query functions shown in the Query Helper dialog This reference page details the query language keywords from the Membership Checks category available in PCB and PCB Library documents in Altium Designer. For help on a specific query keyword, use the following collapsible sections or highlight (or click inside) any given keyword in the Query Helper or a Filter panel, then…

Parent page: Working Between the Schematic and the Board Related Resources Creating Connectivity Compiling and Verifying the Design Whether you're transferring a captured design to a new PCB for the first time, or making changes to an existing design on either the schematic or PCB side, some way of keeping the two sides in-sync is required. Altium Designer provides a powerful design…

Parent page: Managing Design Changes between the Schematic & PCB Do I have the Constraint Manager? The Constraint Manager is available in a PCB design project only if the Constraint Manager functionality was available at the moment of creating that project (provided you have a sufficient Altium Designer Subscription level and the System.ConstraintManager option enabled in the Advanced Settings…

Altium Designer provides a range of editing tools and capabilities that have been designed to help with making large scale edits to a design. The designer's main tools for large scale, or global, edits are the PCB Inspector panel, PCB Filter panel, PCB List panel, and Find Similar Objects capabilities. The process of editing multiple items in Altium Designer involves three steps: Select the…

Working in harmony with Altium Designer's interactive routing and BGA escape routing capabilities is the pin, differential pair and part swapping system. This feature provides all the benefits of traditional pin-swapping systems, but takes advantage of Altium Designer's intimate understanding of the net assignments in the design. During a pin swap operation Altium Designer analyses the net…
