Electrical Graphic Design
The software offers multiple methods for arranging flat equipment and wiring. When placing flat equipment, the output interface uses a floating window combined with dynamic previews, WYSIWYG functionality, and a flexible right-click menu for easy editing. This enables effortless drawing of power, lighting, weak current, fire protection, transformer and distribution room layouts, as well as lightning protection grounding plans.
All graphic elements are arranged parametrically, allowing one-time information input with automatic annotation and material list generation. The software complies with the latest drafting standard, Building Electrical Drawing Standard (GB/T50786-2012), which includes line libraries, equipment libraries, and component libraries. Multiple custom wire options are available in wire settings.
Wires are automatically rounded based on the chamfer radius set in initial settings. When drawing wires with the AI_S_SC_0 command, intersecting or broken wires remain connected logically, allowing simultaneous selection of all connected wire segments.
Users can input wire information during arrangement and adjust line types with the “text line type” button, supporting the creation of new text line types and setting spacing and position of text on wires. Block text attribute settings are provided in AI_S_SC_1.
