01

Open your file

Preview DWG model-space drawings with fit, pan and zoom using the LibreDWG reader. Compatibility depends on drawing content. Select or drop the file to start processing immediately. Files remain private to your guest session and expire after the configured retention period.

02

What is supported

2D preview only. No paper-space layouts, external references, proxy objects or 3D solids. Fonts and unsupported entities can differ; warnings identify skipped content. No area, volume, mass or CAD measurement. The server must have LibreDWG installed.

03

Read the result responsibly

Display units can be changed without changing source geometry. Confirm source units and material density before using physical properties. A preview is not a manufacturing validation.

A reproducible example

DWG release acceptance requires an authorized real drawing. No measured DWG sample result is claimed; previews do not calculate area, volume or mass.

Repository-generated samples are synthetic test models. Verify your own model's units and geometry before using results.
