OpenCAD Studio User Manual
Files and Drawings
Create and open drawings
Use New for a blank document and Open for an existing DWG, DXF, backup, or autosave drawing. After opening a file from another CAD system, inspect its units, layers, blocks, fonts, raster references, layouts, and model extents.
Save and Save As
Save updates the current drawing. Save As changes its path, format, or version. Prefer Save As when validating interoperability or recovering an older drawing. A successful write does not replace visual inspection of a reopened copy.
Recovery and backups
OpenCAD Studio recognizes drawing backups and autosave-style files where the underlying data is DWG or DXF. If strict loading rejects malformed entities, use the recovery workflow and review what was discarded before continuing work.
External resources
Raster images, underlays, fonts, materials, and external references may depend on paths outside the drawing. Keep referenced files together when moving a project and verify that relative paths still resolve.
