This technology has nodes for many typical graphic objects such
as rectangles, triangles, circles, and arrowheads.
Polygonal and Spline nodes allow arbitrary shapes to be defined.
Text is created with the Text (nonlayout) subcommand of the
New Special Object command of the Edit menu.
Of course, nodes from all other technologies can be used as special
electronic symbols when artwork is generated.
Conversely, these artwork nodes can be used to embellish designs
done in all other technologies.
There are four different polygon styles: opened, closed, filled, and spline. The opened polygon can be drawn with solid lines, dotted lines, dashed lines, or thicker lines. These nodes require that you use the Outline Edit command of the Edit menu to describe them. |
Circles can be outlines or filled. The default shape is round, but elongation of the node produces an ellipse. In addition, by using the Get Info command of the Info menu, the outline circle can be reduced to a portion of the circle (from 1 to 360 degrees).
Arrow heads can be drawn in two different styles: simple or filled. The simple arrow head is the default and consists of two lines. The filled arrow head looks better because it is made of polygons. Use the Technology Options... command of the Technology menu and set the "Arrows filled" checkbox in the "Artwork" section to control this feature.
The illustration below shows how outline information, applied to Artwork nodes, results in different shapes. In each of the shapes, the outline has the same 5 points, as illustrated in the upper-left. The nodes interpret this outline information to produce their shape. Note that the spline curve does not run through the outline points, only near them.
The final feature of the Artwork technology is its ability to set the color of any of its nodes or arcs.
Once a node or arc is placed, use the Artwork Color... subcommand of the Special Function command the Edit menu to change the color or pattern. Predefined patterns are available along the top of the dialog. The overlappable colors are taken from the current color map, which in turn is taken from the most recently selected technology (other than the Artwork technology). | ![]() |
