FX Sketch is a freehand drawing mode for FX Draw. You can draw with your finger on a touch screen or using your mouse and FX Sketch will automatically transform your drawing into a high-quality mathematical diagram. FX Sketch is current in beta but is available in FX Draw.

 

FX Sketch is an alternative user-interface for FX Draw and you always have the full power of FX Draw available to you if you require it.

 

Here is a short introductory video.

General Hints and Tips

Draw big – large shapes are easier to detect.
Don’t draw too fast or too slow.
Don’t round off corners.
Keep it simple – the more complicated the shape, the less likely FX Sketch will be able to detect it. Use lines, circles, triangles, rectangles and arcs rather than trying to draw complicated diagrams in one sweep.
Use your finger or mouse. FX Sketch is optimised for the relatively low level of detail you get drawing with a mouse or your finger. Drawing with a pen can confuse it.
FX Sketch gives you access to most features of FX Draw but, if you really want control, FX Draw is the place to be.
Undo. If FX Sketch misinterprets what you draw, just undo and try again.
Compatibility. FX Sketch and FX Draw are two sides of the same coin. Anything you create in FX Sketch can be edited later in FX Draw and vice-versa.
