Convert SHE to PDF

A supplier may send a MEDUSA4 drawing as .she when the recipient needs a standard file for review, printing, approval, or archiving. Converting it to PDF creates a fixed, widely viewable document, not an editable 3D model.

What the SHE format is

.she is a proprietary CAD drawing format used by CAD Schroer's MEDUSA4 system. In 3D-modeling workflows, an SHE file generally represents an engineering drawing with 2D drafting data, annotations, and views derived from design work; it should not be treated as a portable solid-model exchange format. The format is most common in organizations using MEDUSA or in legacy drawings received from suppliers.

Because SHE is proprietary, generic CAD viewers and online conversion services may not open it correctly. File renaming does not convert the internal format.

What the PDF format is

PDF is a page-oriented document format supported by Adobe Acrobat Reader, web browsers, operating systems, document-management systems, and printers. A PDF can preserve the sheet size, page orientation, text placement, vector linework, and print appearance of an engineering drawing more reliably than a screenshot or ordinary image export.

PDF normally does not retain MEDUSA4 feature history, editable geometry, parametric constraints, CAD-editable layers, assembly structure, or interactive 3D navigation. If the recipient must modify the design, provide the original SHE file or an exchange format such as STEP or IGES when the MEDUSA4 installation can export one.

How to convert SHE to PDF

Use MEDUSA4

1. Open the file in a compatible MEDUSA4 release or on the MEDUSA4 workstation that created it. Check that referenced fonts, symbols, external files, and drawing resources are available.
2. Inspect every view, annotation, dimension, layer, line type, and line weight. Resolve missing references before exporting.
3. Set the intended sheet size, orientation, drawing scale, visible layers, font configuration, and pen or line-weight table in the drawing or print setup.
4. If the installed release provides PDF export, choose its PDF export command, commonly found under File → Export, then select the output page settings and save a file with a .pdf extension.
5. If direct export is unavailable, choose File → Print, select a PDF printer such as Microsoft Print to PDF on Windows or the equivalent system PDF printer, set the exact paper size, and print to a new PDF.
6. Open the resulting PDF and check every page at high zoom. Verify text, symbols, dimensions, clipping, line weights, page orientation, and the intended scale before sending it.

Use an online service only when SHE is explicitly supported

Most general-purpose online converters do not list proprietary MEDUSA4 SHE as a supported input format, and a service that accepts the extension may still misread its drawing data. Use an online converter only if its current format list explicitly identifies MEDUSA4 SHE, confirms vector PDF output, and meets the drawing's confidentiality requirements. For restricted engineering files, use MEDUSA4 locally or an authorized CAD bureau that operates MEDUSA4 and can confirm the required page size, scale, fonts, and vector output.

Quality and compatibility limits

PDF output depends on the MEDUSA4 release, printer configuration, font availability, pen table, line-weight settings, and external references. Missing resources can produce substituted text, absent views, changed symbols, or incorrect line weights. A native PDF export is preferable to a screenshot because it can preserve selectable vector linework; printing to PDF may also preserve vectors, but the result depends on the configured driver.

Use a fixed paper size and disable fit to page or other automatic scaling when the PDF must retain the drawing's nominal scale. A PDF is still unsuitable for dependable measurement unless its page size and export scale have been verified.

For a 3D view, set the required projection, camera orientation, display mode, and visible components in MEDUSA4 before exporting. PDF preserves that selected page view, not the interactive model, solids, assembly relationships, or CAD metadata.
