Curves and shapes are easily created using either the Pen Tool or the Pencil Tool. The Pen Tool has several modes that change the way the curve is drawn.
Pen—drag on the page to create repeated nodes; repositioning the displayed off-curve control handles at each node defines the shape of the next segment as you lay down nodes.
Smart—tap repeatedly on the page to lay down each node; a best fitting curve is created without need for control handle adjustment.
Polygon—tap repeatedly on the page to lay down each node; a line is created with sharp nodes made up of straight segments.
Line—drag on the page to create a simple single-segment straight line that self-terminates.
To terminate the curve without closing it, either double-tap the last drawn node or choose the Deselect icon at the bottom left of the workspace.
To continue an existing curve:
With the Node Tool active, tap once on the final node on the path that you want to continue drawing from.
Continue to place new nodes as needed using the Pen Tool.
To change a curve or shape's stroke width:
On the Stroke panel, adjust the Width via slider or input absolute values, expressions and formulas (percentages).
To close curves to create a custom shape:
Do one of the following:
When creating the curve with the Pen Tool, tap on the starting node to join it to the final node and create the shape.
With the curve selected with the Node Tool, tap Close on the context toolbar.
To draw precise curves with the Pen Tool:
To terminate the curve without closing it, either double-tap the last drawn node or choose the Deselect icon at the bottom left of the workspace.
To continue an existing curve:
With the curve selected with the Node Tool, tap Close on the context toolbar.
