How to open .DOR files on Mac

To open .DOR files on Mac, install and open Graphisoft Archicad, then load/import the .DOR file via Archicad’s library/object mechanisms.

Step-by-step instructions

  1. Install and open Graphisoft Archicad, then load/import the .DOR file via Archicad’s library/object mechanisms.
  2. If Finder won’t open it, Control-click → Open With → select Archicad.
  3. If you only need to inspect what it is, do not rename it; instead confirm with the sender that it is an Archicad Door library part and request a more shareable format if you are not an Archicad user.

Alternative methods

  • Open .DOR in a browser-based viewer if desktop apps fail.
  • Try opening .DOR on Mac with a secondary app to rule out app-specific issues.
  • Convert .DOR only with trusted tools when direct opening is not possible.

Common issues

Windows/macOS says it can’t open the .DOR file

This usually happens because the system doesn’t have an application associated with .DOR, or Archicad is not installed.

  1. Install Graphisoft Archicad and open the file through Archicad’s library/object workflow.
  2. If Archicad is installed, use “Open with” and explicitly pick Archicad, then set it as the default for .DOR if you frequently receive these files.

The .DOR file opens, but the door/object is missing or not usable in the project

Library parts can depend on how libraries are loaded and how the project/library paths are set up inside Archicad.

  1. In Archicad, confirm the relevant library is loaded and that the .DOR file is included via the library management workflow.
  2. Ask the sender for the complete library package needed for the object (not just a single .DOR file) if you suspect dependencies.

You’re trying to open .DOR on mobile (iOS/Android) or Linux

.DOR is not a common consumer document format and typically requires Archicad on desktop platforms.

  1. Move the file to a Windows or macOS computer with Graphisoft Archicad installed.
  2. If you only need a visual reference, request a separate deliverable from the sender that is intended for viewing (rather than a library-part source file).

The file seems to be the wrong type (unexpected content/behavior)

File extensions can be misapplied. A .DOR file should come from an Archicad/GDL library context; otherwise it may be mislabeled.

  1. Verify the source and context: was it exported from or used by Archicad as a door library part?
  2. If uncertain, do not force open it with unrelated apps; ask the sender what application created it and request the correct file or a different format.

Security note

.DOR files are commonly tied to Archicad’s GDL/library part ecosystem; treat them as inputs to a complex parser (Archicad). Only open .DOR files from sources you trust.
