Lines, Curves and Shapes 45
Once a square end node or interior node is
selected, the node becomes highlighted and off-
curve rounded control handles for all line
segment(s) will appear. A single control handle
shows on an end node; a pair of handles will show
on a selected interior node.
Remember that a segment is the line between two
nodes; each node provides two control handles,
with each handle controlling different adjoining
segments. One control handle in a segment works
in conjunction with the control handle on the
opposite end of the segment.

4. Drag any selected node to reshape adjacent segment(s).
5. Drag one or more control handles to produce very precise changes
in the curvature of the line on either side of a node. You can shorten
or lengthen the handles, which changes the depth of the curve (that
is, how far out the curve extends), or alter the handle angle, which
changes the curve’s slope.
