Bezier Points are invisible guide points on lines. Moving the Bezier Points will cause the line to warp. The number of these points initially on a line (Line Segment, Arrow, side of a Polygon,etc.) is set during the Path’s construction using the Bezier Point Button. If the button looks like this, you will have one Bezier Point on the side and if it looks like this, you will have two Bezier Points on the side. [Read More]

Models Everything you create is a Model. A Model is just the collection of all the Paths you’ve created (Lines, Circles, Triangles, Grids, etc.) and the actions you’ve performed on them such as Moving, Rotating, or Changing Color. You can save your models either on your device or in the Cloud, and you can load them from there in many different ways. You can use them as building blocks by appending them to your current Model.

When you want to create an image of your drawings, you’ll need to use either one of the Icon tools or else take a Snapshot. The “Take Snapshot” option is available in the application tray along with the “View Snapshots” option. Unlike an Icon (which captures only a section of the screen), the “Take Snapshot” option will capture the entire screen and possibly even some offscreen area. [Read More]

A Background Image is an image imported into your Model from another app (such as Google Photos) and sits on top of the Paper. The main reason for attaching a Background Image is to mark up the image using the drawing tools. For example, You attach a Background Image by using the “Background Image” option in the app tray. Notice the “*” which appears beside the option when a Background Image is currently attached. [Read More]

The concept of Binding is fairly easy to understand. You use one of the Bind tools to form a single path from a collection of paths. After the paths are bound into one single path, you can Move it, Flip it, Rotate it, or perform any other action on it just as you would on a regular path. Layer Binding is a little different. The collection of paths is still bound into a single path, however when the collection is rendered (drawn), the first layer of every path is drawn first, the second layer of every path is drawn next, and then finally the third layer of every path is drawn.

The Arc Reshape tool allows you to reposition the Bezier Points on the side of a path (polygon or line segment) so that the side bows outward or inward. Drag your finger nearer or farther from the midpoint of the side to increase or decrease the amount of bowing and to switch the side of the bowing. At the midpoint itself the bowing will appear to be a half circle. See also the Reshape Side tool for more ways to reshape the Bezier Points on a side. [Read More]

The Change Bezier Point Number tool allows you to change the number of Bezier Points on the sides of certain paths. Any polygon or segment has Bezier points. The number of points initially on a side of a path is set during its construction using the Bezier Point Option Button. This will set the initial number of Bezier points for all sides of the path. If you want to change that number after construction, you can use this tool. [Read More]

The Move Bezier Point tool lets you stretch the straight sides of many paths (Rectangles, Triangles, Regular Polygons, etc.) by moving their Bezier points. Bezier points are guide points that control the drawing of the side. By default, they lie on the side itself so the side is simply drawn straight. However, if you move them, you can create many interesting effects. You can lock onto a Bezier point in two ways: Touch it directly if you know where it is. [Read More]

The Reset Bezier Points on Side tool will return all the Bezier Points on a side of a path to their original positions thus making the side straight again. You can reset the Bezier points in two ways: Simply touch the Bezier point if you know where it is. This might be difficult since the points are invisible. Select a path by touching one of its Snapping Points (such as a corner or center) and then drag your finger onto one of the Bezier points. [Read More]

The Reshape Side tool will adjust the Bezier Points on the side of certain paths (polygons and segments) so that the side is reshaped into either: a custom shape defined using either the Sample Bezier Point Tool or the Custom Transformation Dialog (explained below) or a stock shape such as a half circle, an inverted half circle, a sine wave, or one of several other preset Bezier Point configurations.
