Sketchpad Explorer can open any document created by The Geometer's Sketchpad Version 5, and most documents created by The Geometer's Sketchpad Version 4.
Drag geometric objects to explore mathematics.
With Sketchpad Explorer's multitouch capability, you can drag multiple objects simultaneously.
Tap action buttons and Hot Text® links to perform actions.
Action buttons and links can show, hide, and move objects, or link to other pages or documents.
Drag the background with two fingers to scroll; pinch to zoom.
Flick or drag boxed parameter (number) values up to increase their value, or down to decrease their value.
Tap boxed parameter values to enter new values.
When changing a parameter's value, the Value Edit keypad appears. Enter digits or the decimal point by tapping them, and basic arithmetic operations by tapping the More Options (...) button. Tap the checkmark to accept your changes, or X to cancel them.

Tap the Magnifier button once to magnify your next touch.
When a touch is magnified, a Magnifying Glass displays a zoomed-in area around your active touch. Resize the Magnifying Glass by dragging its top handle. Use the Magnifying Glass to see increased detail or to browse zoomed-out sketches. Or tap or press the Magnifying Glass itself with a second finger to tap or press the object visible in its cross-hairs. If you double-tap the Magnifier button, it "engages" for all future touches. Tap the Magnifier button a third time to release it.
Tap the Library button to access Sketchpad documents.
The Library displays both Local and Networked Documents. Local Documents are personal Sketchpad documents that you've shared with your iPad from a desktop computer using iTunes—see below for instructions on adding Local Documents. Networked Documents are documents published by KCP Technologies and made available to all users of Sketchpad Explorer, and are only available when your iPad is connected to the internet. Tap any document in the Library to open it.
Or open Sketchpad documents directly from e-mail or the web.
To open a Sketchpad document (.gsp file) attached to a message in Mail, tap the attachment. To open a Sketchpad document linked from a web-page in Safari, tap the link. Your iPad will confirm you wish to open the document in Sketchpad Explorer before continuing.
Visit Settings | SketchExplorer to modify Sketchpad Explorer's basic behavior.
Settings permits you to display touch indicators and to control Networked Documents in the Library. Touch indicators visibly track your fingers' locations on the iPad screen, and are especially useful when projecting your iPad screen to viewers who cannot see your hands. Networked Document settings allow you to turn on and off the display of Networked Documents in the Library, as well as choose the URL from which Sketchpad Explorer loads Networked Documents. (Leave the URL blank to return to the default collection of Networked Documents.)
To install Local Documents:
- Connect your iPad to your computer and start iTunes.
- In iTunes, select your iPad from the list of Devices and open its apps tab.
- In the window section titled File Sharing, choose SketchExplorer from the list of apps that can transfer documents between your iPad and your computer.
- Drag and drop Sketchpad documents (.gsp files) from your computer to the list of SketchExplorer Documents.
