Chamfer Support

Chamfer is a viewer for CAD drawings on iPhone and iPad. This page answers the questions we hear most. If yours isn’t here, write to us:

Reporting a Problem

A drawing that doesn’t open, or that looks different from how it looks in your CAD program, is the most useful thing you can send us. Please include:

What happened, and what you expected to see.
The drawing, if you are allowed to share it. We use it only to find the fault.
A screenshot of what the App shows.
The App’s version, which is at the bottom of the Settings screen, and your device model and iOS version.

Opening Drawings

Which files does Chamfer open?

DWG and DXF drawings, and DWF and DWFx sheets. Chamfer shows drawings and exports them to PDF. It doesn’t edit, measure or mark them up.

How do I get a drawing into the App?

In Mail, Messages or another app, tap the file, then tap Share and choose Chamfer.
In the App, use the import button and pick the file in the Files app.
On iPad, drag the file onto the App’s library.
In the Files app, copy the file into the Chamfer folder under “On My iPhone” or “On My iPad”.

The text in my drawing looks different

Many drawings use AutoCAD’s own fonts (files that end in .shx), which can’t be shipped with other apps. Chamfer draws such text with a similar font of its own, so letters can be a little wider or narrower than in AutoCAD.

If you have the font files, copy them into the Fonts folder inside the Chamfer folder in the Files app, then open the drawing again. Chamfer then draws the text with them.

Part of my drawing is missing

Chamfer doesn’t draw 3D solids and a few rare kinds of objects, and it shows pictures and other drawings that a drawing refers to only when those files are in the library next to it. If something else is missing, please send us the drawing.

Open a drawing and use the export button. You can export the current view or every layout, choose the paper size, the scale and the colors, and then share the PDF or print it.

Layers that the drawing marks as not to be plotted are shown on screen and left out of the PDF and the print, as in AutoCAD.

Subscription

What is free, and what needs the subscription?

Importing files and keeping your library in order is free. Opening drawings needs a Chamfer subscription, weekly or yearly. New subscribers get a free trial.

How do I cancel or change my subscription?

Open the Settings app on your device, tap your name, then Subscriptions, then Chamfer. Deleting the App doesn’t cancel the subscription. See Apple’s guide: If you want to cancel a subscription from Apple.

On the screen that offers the subscription, tap Restore Purchases. Make sure the device is signed in to the Apple Account you subscribed with and is online.

How do I get a refund?

Purchases are handled by Apple, so refunds are too. Ask for one at reportaproblem.apple.com.

Your Drawings and Your Privacy

Your drawings stay on your device. Chamfer doesn’t upload them anywhere. Deleting the App deletes the drawings it keeps, so copy out the ones you need first, with the Files app.
