Settings

The Settings Button can be used to access general purpose actions for software usability and performance. It is accessible in the Top Toolbar within the Drawing Editor.

When the Settings Button is pressed, a popover menu will appear as shown below.

Click or Tap on the corresponding Settings Menu item name to learn more about what the option does.

Option Name Description
Show Grid The Show Grid option toggles the visibility of the grid. The grid visibility is an application level preference. It will remember what you have selected through the application restart and will apply to all drawings that you edit/view.
Snap to Grid The Snap To Grid option toggles the snap to grid functionality. The snap to grid is an application level preference. It will remember what you have selected through the application restart and will apply to all drawings that you edit/view.
Snap to Lines The Snap to Lines option aligns figures with the nearest lines.
Snap to Shapes The Snap to Shapes option snaps a figure to a selected shape vertex or center point. 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.
Snap to Pixels The Snap to Pixels option aligns figures to whole pixel numbers for simplified object modification and increased accuracy. This option remains disabled until the Unit of Measure for the drawing is changed to pixels.
Snap to Points The Snap to Points option aligns objects to points on the grid for simplified modification and increased accuracy. This option remains disabled until the Unit of Measure for the drawing is changed to points.
Easy Drag Mode The Easy Drag Mode option makes it simpler to move and select figures without having to worry about touching one of the handles (which could lead to an unwanted resize). This is also particularly useful when trying to move a small object, without having to zoom way in.
Show Overlays The Show Overlay option toggles the visibility of the various overlay tools, which are covered in detail in the Overlays section of the documentation.
Crosshairs The Crosshairs option tells TouchDraw to draw crosshairs in the editor panel for every touch done within the editor. This means that multiple crosshairs will appear on the screen for multi-touch gestures.
External Display The External Display option allows the current drawing to be shown on an external monitor when a supported cable is connected to the iPad (such as the Apple VGA Adapter). Once connected, the button can be used to turn on or off the external display support.
Handles Submenu The Handles Submenu contains options for configuring which handles will be visible for figures residing on the Drawing Canvas.
Usability Submenu The Usability Submenu contains options for application setup and operational characteristics.
Performance Submenu The Performance Submenu contains options for impacting Drawing Editor performance. Specifically, these options will help speed up zooming and panning when zoomed in by a large factor on drawings using many shadow or gradient effects.
