Schematic document editing ( component placement, connectivity editing and design rules definition).

Schematic capture module provides electronics circuit editing functionality, including: In April 2011 Altium moved from Australia to Shanghai in China and most workers in Sydney were made redundant.

Protel 99 introduced the first integrated 3D visualization of the PCB assembly, and Altium Designer version 6.8 from 2007 was the first to offer 3D visualization and clearance checking of PCBs directly within the PCB editor. The launch of Protel 98 in 1998 saw the consolidation of all components, including Protel Advanced PCB and Protel Advanced Schematic, into a single environment. In 1987, Altium launched the circuit diagram editor Protel Schematic. Originally sold only in Australia, it has been exported to the United States and Europe since 1986.
