Frequently asked questions

Which devices does the app run on?

DWF View is a single app for Mac, iPad and iPhone. It needs macOS 14 or later, or iPadOS and iOS 17 or later. One download, one purchase: the Pro upgrade is shared across your devices through your Apple Account.

What formats are supported?

.dwf, .dwfx and .dxf drawings, including multi-sheet sets and older DWF files, with a sheet list and thumbnails to move between pages. AutoCAD and Design Review are not required.

Which DXF files open?

Text (ASCII) DXF. A binary DXF can be saved again as ASCII DXF from the CAD program.

Can it open 3D DWF files?

Not yet. DWF View shows 2D drawing sheets; a DWF that contains only a 3D model is reported as such.

What is included in the free version?

Opening and viewing any supported drawing, one drawing at a time: multi-sheet sets with sheet list and thumbnails, zoom, pan and rotation by gesture, trackpad or mouse, zoom to a rectangle, arrow keys to move between sheets, recent drawings on the start screen, heavy sheets opened simplified with "Show Everything", a dark sheet, and light or dark appearance.

What does the Pro version unlock?

Measurement of distances, areas, angles, radii and counts with snapping, the scale read from the title block and manual calibration, markup (revision clouds, arrows, callouts, notes, highlights, freehand), comments exported as CSV, CAD layers, object properties, Capture View, comparing two revisions (Mac and iPad), text search across every sheet, several drawings open in tabs, renaming and removing sheets, saving as DWF or DWFx, combining drawings, export to PDF at real paper size, PDF/A-2b, PNG, SVG and DXF, and printing. It is a single one-time in-app purchase, with no subscription.

Is there a free trial?

Yes. Every Pro feature, free for 14 days, once per Apple Account. It never renews and never charges; if you don't buy, the app goes back to the free features and keeps your comments and markup.

What does Pro cost?

A single purchase, with no subscription: €19.99 in Portugal, and the App Store's equivalent in other countries. It covers your Mac, iPad and iPhone.

How do I unlock Pro?

Through the in-app purchase, available from any screen with a locked feature.

How does measurement scale work?

Measurement is part of Pro. The scale is detected automatically from the drawing's own title block, for example "1:100", and imperial scales such as 1/4" = 1'-0" are read too. When a drawing has no title block, or the detected scale is wrong, Pro lets you calibrate manually against any known dimension.

Does it work in feet and inches?

Yes. Measurements can be shown in metric or imperial units, and imperial scales such as 1/4" = 1'-0" are read from the title block.

Will a PDF print at the right scale?

Yes. PDFs come out at the drawing's real paper size, so printing at 100 % keeps the drawing's scale.

How do I open a drawing?

From Finder or the Files app, from Mail, from any app that can share a document, or from within DWF View itself.

Which languages?

English, Portuguese, Spanish, French, German, Italian, Japanese and Korean. The translations were prepared with the help of AI; if you spot a mistake, please tell us at hello@byn.pt.

Can I use the app in another language than my device?

Yes: Language… in the app (on the Mac in the DWF View menu, on the iPhone in the … menu, and on the start screen of the iPhone and iPad) opens the system settings where you choose a language for this app only.

Does the app work offline?

Yes. All conversion, rendering, measurement and export happens on your device. An internet connection is only needed to process the Pro purchase.

How do I restore my Pro purchase?

Use the restore option on any screen showing a locked feature. The purchase is tied to your Apple Account and works on all your devices.
