Paint > Shape > Make Mask Shape

Creates a mask from curves.

Ensure that you are working on a paint layer. Mask shapes cannot be created on shape layers.

Choose Paint > Shape > Make Mask Shape from the palette.
The Shape Editor opens, and you are prompted to
```
Select a curve
```
Click each curve to include in the shape. (Make sure that you click the part of the curve that you want to include in the shape boundary.)
Note
Do not drag a pick box around complex curve structures, or the shape may not appear as you expect.

The curves are highlighted. You are prompted to
```
Select another curve. If done, press ACCEPT button.
```
Click the Accept button.
The curves becomes a mask. By default, the outline is turned off, and the fill area, which acts as the mask, is outside the curves.
Set Fill to Inside in the Shape Editor, if you want the fill area (mask) to be inside the curves.
The Shape Editor lets you modify several parameters of the Shape such as color, opacity, and so on.

For a description of each option, see Windows > Editors > Shape Editor.

Note

To create certain shapes, you may need to select the curves that define the shape in more than one location. Simply select each curve segment that forms a boundary of the shape region, even if you must select the same curve more than once. See Create a shape for more details.
