The Rectangle Layer represents a rectangular shape that can be filled, outlined, and optionally rounded at its corners. It is one of the most versatile visual Layers, used for creating backgrounds, frames, highlights, or colored regions within a Layout.

This Layer can be created with the “Draw Rectangle” tool in the Tool Select Toolbar.
Properties #
This Layer supports all of the universal Layer properties along with some of its own.
Fill #
This property is of the Brush Property type, which allows for color and visual styling of the Layer.
The Fill brush determines how the inside of the shape is rendered.
Stroke #
This property is of the Brush Property type, which allows for color and visual styling of the Layer.
Defines the outline color or style of the rectangle, drawing around the rectangle’s border.
Stroke Thickness
Controls the width of the line in the project’s current base units.
Round X & Round Y #
Controls the curvature of the rectangle’s corners on both horizontal and vertical axes.
Round X defines the horizontal corner radius.
Round Y defines the vertical corner radius.
- Both values must be greater than 0 for rounding to take effect.
The Brush properties of this Layer will always draw within the borders set by this property.
NOTE: These properties affect only the visual shape and do not change the Layer’s alignment or Layout dimensions.

Opacity Mask #
This property is of the Brush Property type, which allows for color and visual styling of the Layer.
Applies a mask effect over the rectangle’s rendered content to control how it blends or fades. This can be used to create gradient transparency, fade effects, or highlight shapes.
The opacity mask affects both Fill and Stroke uniformly, without changing geometry.
