Resetting the QCAD Configuration

Introduction

If your configuration is somehow damaged and you cannot get it back to normal, you might want to reset QCAD to its default settings as they were when QCAD was first installed.

This will affect:

• arrangement and visibility of toolbars and dockable widgets
• arrangement and visibility of tools
• user interface language
• default settings for new drawings
• etc.

Step 1: Quitting QCAD

Make sure that QCAD is closed before resetting the configuration.

Step 2: Deleting the QCAD Configuration File
