I love doing both formal and informal modeling in Dia. However, sometimes the grids and other visual clutter bothers. There's 2 in-page items (the Grid, and Page Breaks) and the Rulers.
We're aiming for this:
Turning off Grid, Rulers and Page Breaks
- Click View -> Show Grid (to turn off showing the grid)
- Click View -> Show Rulers (turn off)
- Click File -> Preferences -> [View defaults] -> "Page Breaks" -> Visible (turn off)
That 3rd step was the thing I had been looking for a long time!
