Lines tab

Outline

If this option is enabled, lines are drawn for all outer edges and intersecting lines.

Edges Angle

If this option is enabled and two polygons face each other at an angle greater than the one entered, they are drawn as edges.

Width

This slider defines the vector line width and ranges from 0 to 20. A value of 0 creates a hairline which is still drawn as a hairline even if the SWF file is scaled larger in the Internet browser. When using values above 0, the lines are scaled with the document. An SWF file with an optimal size of 320 x 240 pixels and a line width of 1 pixel will display a line width of 2 pixels if it is scaled to a document size of 640 x 480 pixels.

Merge Planes

If a spline is extruded using Extrude NURBS, the caps consist of many triangles and the resulting vector lines are usually unwanted. If this option is enabled, the lines of these caps are not drawn. This option is only relevant when using the Wireframe or Hiddenline modes.

Merge Planes disabled.

Merge Planes enabled.

Color, Brightness, Transparency

These sliders control the color and opacity of the lines. Setting the line color to black and setting Transparency to 80% results in slightly visible lines which let the object color shine through.
