About This Tool

The tool is a web-based DGN viewer designed to load MicroStation designs and render 2D and 3D content in the browser. It exposes layer visibility controls, view selection, and measurement capabilities to facilitate quick geometry checks and design reviews.
Conceptually, it parses DGN binaries on the server, constructs an in-memory scene, and streams a rendered viewport to the client. It emphasizes deterministic rendering, data security, and minimal client requirements; no local CAD installation is needed.
Target users include engineers, CAD managers, construction coordinators, and design consultants who need fast previews, accurate measurements, and straightforward exports. Unique value lies in browser-only access, fast rendering, multiple export formats, and session-based sharing.
Core features include DGN upload (or URL), 2D/3D viewing, layer toggles, distance/area/volume measurements, viewport snapshot exports in PNG, PDF, DXF, or SVG, and secure sharing. Typical use cases cover early design reviews, field coordination, and delivery of constructible drawings.

Frequently Asked Questions

Find Quick Answers

What file types are supported?

The tool accepts DGN files for viewing and supports exporting to common formats such as PNG, PDF, DXF, and SVG. It does not edit the DGN content.

Is there software installation required?

No installation is required. The tool runs in a modern web browser and uses server-side parsing and rendering; a stable internet connection is recommended for large files.

How secure is my data?

All data transfer uses TLS, sessions are ephemeral, and uploads are not retained by default unless the user opts to store results; enterprise configurations may enforce stricter data policies.

Can I export measurement data?

Yes; the tool provides numeric measurement results for length, area, and volume with unit annotations, and exports can include data in CSV or be embedded in PNG/PDF exports.
