Open a drawing set
Use Open files for individual drawings, or Open folder to preserve folder paths and locate external references. Select the main drawing in the Drawing set list. Missing references appear in the References panel.
Explore models and sheets
Choose a model or paper layout from Models & sheets. Search the Layers panel and check a layer to show it, or uncheck it to hide it. These view changes do not modify the source file.
Navigate and measure
Scroll to zoom, drag to pan, and use Fit to return to the drawing extents. Measurement results use the drawing's units; they are an aid to viewing, not a substitute for authored dimensions.
Format support
DWG and DXF drawings are opened directly in the browser. DGN requires conversion to DWG or DXF using a CAD application first. Review import notes for missing references and content that could not be displayed.
Privacy
The viewer reads files you select in this browser session. Drawing files are not uploaded to a server. Closing or refreshing the page clears the drawing session.
