Report an issue View project

Before reporting a problem

  1. Update IFC Viewer to the latest App Store version.
  2. Close and reopen the app.
  3. Try opening a smaller IFC file to confirm whether the issue is file-specific.
  4. Restart the device if the app continues to behave unexpectedly.

Include these details

  • Device model and operating-system version.
  • IFC Viewer version and build number.
  • IFC schema, such as IFC2X3 or IFC4.
  • Approximate file size and what happened.
  • Screenshots or a screen recording where possible.

Common questions

My IFC file does not open

Confirm that the file has an .ifc extension and has finished downloading to the Files app. Very large or highly detailed files may require more memory and take longer to process.

The model looks incomplete

The source export may contain hidden objects, unsupported geometry, missing representations or external references. Check the same file in another IFC viewer to help establish whether the issue is in the file or the app.

The app becomes slow with a large model

Close other apps, reopen IFC Viewer and reduce the complexity of the source export where possible. Splitting a large federation into smaller discipline models can also improve performance.

How do I send a useful bug report?

Use the “Report an issue” button above and describe the exact steps needed to reproduce the problem. Do not upload confidential project models publicly. A simplified test file is much safer and easier to diagnose.
