Shape Styles

Diagrammix3 allows you to save and reuse styles.

Quick Styles

The Shape Action Toolbar (floating near selection) or the Inspector provides access to quick styles—a set of predefined color combinations and visual effects.

Copying and Pasting Styles

You can copy the style of one object and apply it to another:

Select the source object.
Choose Edit > Copy Style (or use shortcut).
Select the target object(s).
Choose Edit > Paste Style.

Default Style

You can set the current style as the default for new shapes via the Format menu.

Copy Style Workflow

What Gets Copied

When copying a style, the following properties are included:

Fill: Color, gradient, or pattern
Stroke: Color, width, dash pattern
Shadow: All shadow settings
Opacity: Transparency level
Corner radius: For applicable shapes
Font settings: Family, size, color, style

Step-by-Step

Select source object: Click the object with the style you want
Copy style: Go to Edit → Copy Style (Cmd+Option+C)
Select targets: Click or Shift-click objects to receive the style
Paste style: Go to Edit → Paste Style (Cmd+Option+V)

Selective Paste

If you only want certain properties:

Paste normally, then undo specific changes in Inspector
Or manually match individual properties

Tips for Copy Style

Works across different shape types
Text formatting is included when copying from text objects
Connector styles can be copied to other connectors
Style paste affects all selected objects simultaneously

Setting Default Styles

Make Current Style Default

Style an object exactly as you want new objects to appear
Select the object
Go to Format → Make Style Default

New shapes will now inherit this style.

Reset to Application Default

To restore original default styles:

Format → Reset Default Style

Per-Shape Defaults

Different shape types can have different defaults:

Create a rectangle with your preferred rectangle style
Make it default for rectangles
Do the same for ellipses, connectors, etc.
