Convert SHE to DWG

A recipient using AutoCAD or another DWG-based CAD system may be unable to edit a native MEDUSA drawing stored as .she. Exporting it to DWG makes the geometry available for downstream editing, exchange, and plotting.

What the SHE format is

SHE is a native 2D drawing format associated primarily with MEDUSA4, the engineering CAD system developed by CAD Schroer. It is used for mechanical layouts, schematics, engineering drawings, and related MEDUSA drafting data, and is most often found in legacy engineering archives or organizations that still operate MEDUSA4.

SHE is not a general CAD interchange format, so ordinary DWG utilities normally cannot open it directly. Confirm that the file originated in MEDUSA4 before converting it; other software can use the same three-letter extension for unrelated formats.

What the DWG format is

DWG is the native drawing format associated with AutoCAD and is supported by many professional CAD applications. It can store vector geometry, layers, blocks, dimensions, text, layouts, and, where supported, 3D objects and drawing metadata.

DWG is suitable when the recipient must edit the drawing in AutoCAD or another DWG-capable system. Select the DWG version required by the recipient: older CAD releases may not open files saved in newer DWG versions.

How to convert SHE to DWG

1. Open the .she file in a MEDUSA4 installation that includes the required SHE reader and CAD export interface. Use File → Open or the equivalent MEDUSA4 drawing command.
2. Check units, sheet scale, layers, line types, text styles, dimensions, title blocks, fonts, and external references. Resolve missing resources in MEDUSA4 before exporting when possible.
3. Use MEDUSA4's CADConvert or the version-specific export command. Some installations can write DWG directly; if a DWG option is available, select the DWG version required by the destination system and export a copy of the original.
4. If direct DWG output is unavailable, export .dxf instead. The command may appear as File → Export → DXF or File → Save As with DXF selected. Choose a DXF version supported by the target CAD program.
5. For a DXF intermediary, open the exported file in AutoCAD, BricsCAD, DraftSight, or another CAD application that can save DWG. Check the import units and scale, measure a known dimension with DIST, then use File → Save As to select the required DWG version.
6. Run AUDIT in AutoCAD or the equivalent repair command, then inspect layers, text, dimensions, line types, blocks, hatches, and plotted output at several zoom levels.

The ODA File Converter can convert supported DXF and DWG versions after MEDUSA4 has produced a DXF file. It is not normally a SHE reader and cannot replace the MEDUSA4 export step.

An online service such as CloudConvert may be suitable for a nonconfidential DXF-to-DWG conversion if its current format list explicitly supports both formats. Do not assume that a service advertising DXF-to-DWG can read SHE, and do not upload confidential engineering drawings unless its retention, deletion, and security terms are acceptable.

Quality and compatibility checks

The export may convert MEDUSA-specific entities into ordinary lines, arcs, text, blocks, or dimensions. Parametric constraints, proprietary symbols, associative behavior, hatches, fonts, line weights, external references, and application-specific annotations may be lost or require manual reconstruction.

Strictly 2D drawings usually transfer more predictably than drawings containing linked resources or proprietary objects. DXF files may omit or misinterpret unit metadata, so verify scale against a known dimension rather than relying only on the imported unit setting.

Keep the original .she file and any exported .dxf beside the final .dwg. Compare the DWG with the source for geometry, scale, layer visibility, text, dimensions, title blocks, and printed or plotted appearance before delivery.
