DXF Viewer: 2D CAD Viewer for Industrial Workflows

DXF Viewer is a small desktop application for one job: opening a DXF file and looking at it properly. AutoCAD and similar suites are heavy, slow to launch, and overkill when all someone needs is to verify a CNC job, inspect a layer, or review a drawing before sending it to the floor. This tool starts in seconds, renders accurately, and stays out of the way.

What it renders: All the common DXF entities including LINE, CIRCLE, ARC, POLYLINE, and TEXT, with antialiasing tuned to keep large files readable.

Working with the drawing:

• Layers: Toggle visibility per layer, navigate between layers, and read a color-coded layer tree
• Navigation: Mouse wheel to zoom, mouse drag to pan, and automatic centering when a file opens
• Selection: Click-to-select, CTRL-click for multiple entities, and area selection
• Performance: Optimized rendering paths for large drawings so big DXF files do not freeze the UI

Interface:

• English and Turkish UI with dynamic language switching
• Settings persist between sessions through a simple JSON store
• PyQt6 layout that stays usable on the kinds of screens that show up on a manufacturing floor

Stack: Python 3.7+, PyQt6, ezdxf for parsing, NumPy for the math.

Where it fits: Reviewing CNC jobs before they run, inspecting drawings on a shop-floor terminal, sanity-checking documentation for mechanical engineering reviews, and any other task that does not need full CAD authoring.
