This feature is not available in SurfaceStudio.
A shape is a way to create a precise image that you can easily modify.
A shape's shape is defined by a curve or set of curves. You can create a shape from any StudioTools curve, including curves-on-surface and surface edges. A shape also has fill and outline properties.
After you create a shape from a curve or set of curves, any changes you make to the curves (for example, scaling a curve or moving an edit point) will update the shape.
You can then use the original curves to build surfaces, and any changes you make to the curves will automatically update both the sketch and the model.
Shapes appear in the Paint Layers window in shape layers. A shape layer (indicated by 
in the Paint Layers window) is similar to an image layer (indicated by 
in the Paint Layers window). An image layer contains paint and a shape layer contains shapes. You cannot use a brush to apply paint to a shape layer. If you try to paint on a shape layer, the cursor will change to a 
.
The first time you create a shape on a sketch image plane, StudioTools automatically creates a shape layer and places the shape on that layer. Similarly, if the active layer is an image layer, when you create a shape StudioTools automatically creates a shape layer and places the shape on that layer. However, if the active layer is a shape layer, then StudioTools places the new shape in that layer.
A shape layer contains an expandable list of all shapes in that layer. Each shape also contains an expandable list of all curves that make up the shape. To view the curves associated with the shape, click on the Curve icon in the image layer editor. To expand a list click the

You can perform the following operations on shapes:
You can also perform most image layer operations on shape layers and on individual shapes, including:
You can also name a shape in the Paint Panel when the shape is selected.
When you select a shape layer, it is highlighted in white.
When you select an individual shape, it is highlighted in yellow (without affecting the active layer selection).
If you duplicate a shape layer, the layer is duplicated and converted into an image layer.
You cannot duplicate an individual shape.
You can export a shape layer as an image file. The size of the image file will be just large enough to contain the shapes in that layer; it may not be the size of the sketch image plane.
You cannot export an individual shape.
To automatically create a shape as you create a curve, turn on Auto-Shape. (Make sure Mask is turned off.)
