No. JWW Bridge is an independent app, not affiliated with the authors or distributors of Jw_cad. It is for viewing, measuring, converting and printing drawings; it cannot edit them (draw lines or save over a JWW file).

Jw_cad .jww, .jws and .jwc files. We have tested drawings saved in Jw_cad v10 and 8.25a. .dxf files open in the view for converting them to JWW. DWG files are not supported. To try the app, click Open Sample Drawing on the start screen.

Choose Jw_cad Users under Recipient in the Export sheet. It writes Japanese text in Shift-JIS. DXF files exported with AutoCAD and Others (UTF-8) can't be read correctly by older versions of Jw_cad, such as 8.25a. See When Japanese text in a DXF is garbled.

DXF files do not store the paper size. When Jw_cad reads a DXF file, it picks a scale that fits the paper size currently set. Set the paper size in Jw_cad to match the original drawing first, then open the DXF. Colors changing to similar ones, layer group names and layer states (such as hidden) not being kept, and multiple scales becoming one are how Jw_cad reads DXF; the same happens with DXF files exported by Jw_cad itself. For Jw_cad users, sending the JWW file itself is the most reliable option.

Choose AutoCAD and Others. It writes a DXF in AutoCAD 2010 format with UTF-8 text. We have confirmed that AutoCAD-based software reads its geometry, text and layers correctly. Text is set to the MS Gothic font, so characters that this font lacks, such as Korean, may appear as "?" in AutoCAD, although the text itself is stored correctly. In that case, change the font of the text style in AutoCAD.

JWW Bridge uses Mac fonts, while Jw_cad uses Windows fonts, so text width and weight can differ slightly. Please check important drawings in the recipient's software. If you notice a difference, tell us where it is and how it differs.

Things the JWW format can't hold are converted to the closest equivalent: vertical text becomes one text per character, random lines become solid lines, and so on. The Result section of the conversion view lists what was converted and how. In older versions of Jw_cad, such as 8.25a, characters that are not in Shift-JIS appear as "?". Always open the converted drawing in Jw_cad and check it before you use it.

No. Viewing and converting happen entirely on your Mac. Drawings are never uploaded, and no account is needed. Viewing and converting drawings don't use the internet. The app connects to the App Store only to start the free trial, purchase, or restore a purchase.

If you don't purchase, you can still view drawings: open them, zoom, pan, switch layers and see Drawing Info. Measuring, exporting, printing, batch conversion, DXF to JWW conversion, text search, the background switch, editing markup, and Quick Look and icon previews in Finder become available when you purchase. See Free trial and purchase.
