Background:
In version 9 we were able to modify the settings in the tools palette to set the default settings for line width or text box while no project was open.
Solution:
However in QuarkXPress version 10 this can be achieved by the following steps:
1. Create a new layout.
2. Create a text or an image box
3. Modify the settings in the measurement palette
4. Go to Edit > Set Tool Preferences from Selected
a. For Current Layout; It would repeat same settings for the tool
b. For New Print Layouts; this would set it as default for all the new layouts as well as the current layout.
