In the first part of this chapter, directives influencing the interpretation of GDL statements are presented.
Directives may define the smoothness used for cylindrical elements, representation mode in the 3D view or the assignment of an attribute (color, surface, text style, etc.) for the subsequent shapes.
Inline attribute definition is covered in the second part.
This feature allows you to assign to your objects customized surfaces, textures, fill patterns, line types and text styles
that are not present in the current attribute set of your project.
