Ray Studio 1.3.0

Ray Studio 1.3.0 adds editable big-square scale markers.

• Grid Scale now displays the real-world length of one big square.
• Edit the value in Properties or in a scale-arrow label; both update together.
• Horizontal and vertical arrows can be moved or deleted independently.
• New arrows meet at the exact top-left paper corner. Reset scale marker position returns existing arrows there after moving them or resizing the grid.
• Restore missing scale arrows brings deleted arrows back.
• Fit page and exports include space for scale labels above the grid.

Existing diagrams keep their real-world measurements. For example, 0.5 m per small square is shown as 2.5 m per big square. To reposition existing markers, click Reset scale marker position.
