Qcad
QCAD is a professional two-dimensional computer-aided drafting application designed for creating technical drawings, engineering schematics, and architectural plans. It provides a comprehensive suite of geometric construction and modification tools that allow users to draft precise layouts while managing complex project structures through layers, blocks, and part libraries.
The software distinguishes itself through an integrated scripting framework that enables users to automate repetitive design tasks and develop custom tools to extend core functionality. It also functions as a manufacturing design tool, supporting production workflows by generating machine-ready output such as G-Code and performing material nesting to optimize fabrication processes.
The application handles industry-standard file formats, including DXF and DWG, to ensure compatibility across different design environments. It supports the creation of scaled documentation for physical or digital output and provides a command-line interface for programmatic file manipulation and automated design workflows.
Features
- 2D CAD Applications - Functions as a professional 2D drafting application for creating technical drawings using industry-standard DXF and DWG file formats.
- 2D Technical Drawing Editors - Drafts two-dimensional technical designs and layouts using a comprehensive set of geometric tools and drafting functions.
- Computer-Aided Drafting - Create two-dimensional technical plans and diagrams using a suite of construction and modification tools to define precise geometric entities for engineering and architectural projects.
- Geometric Entity Graphs - Represents drawings as a collection of interconnected mathematical objects that manage their own properties and spatial relationships.
- Command Patterns - Encapsulates drawing modifications as discrete operations that update the document state while maintaining a history for undo and redo.
- Event-Driven User Interactions - Processes user inputs through a centralized event loop that triggers specific drafting actions based on the current tool state.
