Freehand tool introduction
Use the Freehand tool to draw irregular hand-drawn lines in the form of Curve entities and 3D Polyline entities. Curve entities are comprised of multiple line segments that are connected together. These curves behave as a single line in that they can define and divide faces. They are also connected such that selecting one segment selects the entire entity. Curve entities can be useful for representing contours in a contour map or other organic shapes. Activate the Freehand tool from the Toolbar / Tool Palette or from the Draw menu.
