DWG Viewer

This tool provides an online DWG and DXF viewer designed for French-speaking engineers, architects, and contractors who need to inspect CAD drawings without installing software. It accepts DWG and DXF uploads, preserves the document structure including blocks and layers, and offers interactive viewing features such as panning, zooming, rotating, and layer visibility toggles. The viewer supports common drawing elements like lines, arcs, dimensions, blocks, and annotations and renders them with fidelity suitable for quick validation, coordination, and client reviews. It also generates lightweight previews suitable for email, documents, or briefing sessions, and supports exporting a snapshot of the current viewport for collaboration.
\n\nConceptually, the tool parses the uploaded file into an internal scene graph that represents geometric entities, blocks, layers, and references. It resolves blocks and layer hierarchies, merges attributes, and renders vector geometry to a high-contrast canvas. Users can switch on/off layers, switch between view projections, and measure distances between points. The rendering pipeline aims for performance on typical workstation drawings, using scalable vector rendering to preserve line weights at multiple zoom levels. When a file is large, the tool progressively renders visible portions to maintain responsiveness. Uploads can be discarded after session per policy, reducing exposure of confidential content.
\n\nAudience and differentiation: francophone engineers, architects, supervisors, and contractors who need rapid CAD previews without local CAD software. Unique value propositions include a true no-installation workflow, reliable layer management, and export options for sharing results. Core features consist of DWG/DXF upload, layer visibility control, viewport navigation, basic measurements, and image export in PNG/JPEG. Use cases include site coordination, equipment layout checks, design reviews with clients, and field inspections on-site. By focusing on viewing accuracy, reasonable performance, and clear localization, the tool supports efficient collaboration across distributed teams.
