PCB API Functions reference

Created: May 13, 2013 | Updated: March 06, 2024

Note: The Altium Designer SDK is currently in the Beta phase and therefore evolving along with its documentation. This reference document, derived from the Altium Designer RTL documentation, is a work in progress and includes some aspects that are different to the new SDK.

The major PCB Functions are defined and implemented in the RT_PCBProcs unit.
