Attribute Checks

At a Glance

This reference page walks you through the Attribute Checks category of query keywords available in Altium Designer for PCB and PCB library documents, showing how each keyword is used to find component objects based on pad rows and columns, centroid positions, and pin counts across different layer types. It is a practical lookup resource for understanding the syntax, example usage, and returned results for each query in the Query Helper or Filter panel, so if you want a clearer handle on how these functions behave in real searches, keep reading.

- You will see what each Attribute Checks query keyword does, including row and column counts, component center coordinates, and pad or pin count checks.
- You will learn the expected syntax and review example query expressions for exact values, ranges, and comparisons.
- You will understand what kinds of objects are returned by these queries, including when associated child objects are included.
