Snap to Shapes
The Snap to Shapes option snaps a figure to a selected shape vertex or center point. This option is enabled by default in TouchDraw. To enable/disable this option:
-
Press on the Settings Button in the Top Toolbar.
-
Tap on the Snap to Shapes on/off slider to enable or disable the option. The slider will appear with a green background when this option is enabled.
-
To see this option in action, disable the Snap to Grid option, make certain Snap to Shapes is enabled, and then draw a Star or Rectangle. Once the shape is completed, select the Line Tool and try to draw a line from one of the vertexes of the shape or its center point. The drawn line will snap to one of these locations.
In the example below, the line snaps to the center point of the rectangle.
The Snap to Shapes option will have a green background when enabled or a gray background when disabled.
