Connected Collection of Points

The Connected Collection of Points tool creates a Bound collection of Line Segments from a selected group of Points. It connects every Point to every other Point and will produced a shape like this: You have the option of binding the line segments using normal binding or Layer Binding. You also select how many Bezier Points each line segment will use and whether or not to delete the original Points. [Read More]

Convex Hull

The Convex Hull tool creates a polygon essentially by wrapping a rubber band around a collection of paths. You have two construction options Consider ALL Paths Points Only The Points Only option will only use Points for the wrapping and ignore all other paths. The Consider ALL Paths option will use all the Snapping Points on every path within the selection rectangle. This can be very useful for creating hybrid curved/straight shapes. [Read More]

Mark Point Polygon

The Mark Point Polygon tool is similar to the Point Trace Polygon tool except that instead of laying out Points in advance you “mark” the vertices with the Mark Button Simply move your finger to a position and press the mark button to select the next vertex. You can use the Drag Constraint button to align the next vertex horizontally or vertically with the last vertex. [Read More]


The Point tool creates a point on the page. It is created where your finger first touches the canvas. If you have Snapping enabled, the point may be drawn at a snapping point of another path if your initial touch is near enough to one. Points are useful as guides in the construction of other paths. For example, they can be used with the Point Trace Polygon tool to easily draw an irregularly shaped polygon. [Read More]

Point Along Line

The Point Along Line tool lets you position a point along a line defined by two points. Your initial touch defines the first point of the line. You use the Mark Button

to define the second point. You can also use the Drag Constraint button
to position the point horizontally or vertically relative to the initial point. Here’s an example:

Point by Angle

The Point by Angle tool allows you to create a point which is positioned based on an angle that you define. Your initial touch defines the vertex of the angle. You then drag and use the Mark Button to define the two endpoints of the angle. This is different from how angles are usually defined in Doodleback (it’s usually endpoint-vertex-endpoint), but the reason is that the two endpoints actually define the line on which the point will lie so really what you’re defining is a vertex and then a guide segment.

Point by Intersection

The Point by Intersection tool allows you to construct a Point at the intersection of two lines. The initial touch defines one point of the first line. While keeping your finger on the screen, drag it to another location and tap the Mark Button to define the other end point for the first line. After the first line is defined, keep your finger on the Paper, drag it to another location, and tap the mark button to define the first point on the second line. [Read More]

Point on Each Vertex

The Point on Each Vertex tool creates a collection of Points matching the vertices of a selected polygon. There’s also an option to include the center of the polygon in the collection and a construction option to Bind the Points together at the time of creation. These Points are completely independent of the original polygon. Here’s an example:

Point Trace Polygon

The Point Trace Polygon tool allows you to trace out a polygon using Points laid out on the canvas. First layout the corners of some shape with the Point tool, and then simply trace the shape with your finger. You can easily remove the points after construction by using the Delete Path Collection tool. The only construction options available are the number of Bezier Points and whether or not the first vertex and last vertex are connected. [Read More]
