The thick and thin line drawing mode lets you add depth and detail to your technical illustration and is especially useful when you draw and edit shapes in projected view. Corel DESIGNER automatically splits the shapes and applies thin and thick lines, saving you time and effort. A thin line shows that adjacent object areas are visible; a thick line shows that the area beyond the line is hidden from view.
Use the Thick and thin line drawing mode to quickly add depth and detail to your illustration.
Thick and thin line drawing can also be used with curves and unprojected shapes to ensure consistent line widths in a drawing.
If the line widths applied are not as expected, you can replace thick lines with thin lines and vice versa. You can also separate the thick line applied to a shape so that the thin line becomes the shape outline, and the thick line becomes a separate curve. This feature can be useful when you want to keep only one part of the object.
By default, thick lines use the Thick Line style set, and thin lines use the Thin Line style set. Both style sets meet S1000D requirements. You can change the default style sets in the Options dialog box (Layout Document Options ). For more information about the Thick and Thin Line style sets, see Apply styles and style sets.
The thick and thin line drawing mode is typically used in line art and technical drawings so it doesn’t have fills. If you want to fill an object that has thick and thin lines, you can do so by using the controls on the property bar or in the Properties docker as you would with any other object. This method overrides the styles applied to the object. For information about overriding style attributes and reverting changes, see To override a style attribute. Alternatively, you can apply a fill by modifying the Thick and Thin Line style sets in the Object Styles docker. For rectangles, ellipses, and well shapes, modify the Thin Line style set; for cylinders, prisms, and threads, modify the Thick Line style set. Note, however, that editing the Thick and Thin line style sets will affect all objects using these styles.
With the exception of the Polygon and Star tools, all shape tools, including projected shape tools, support thick and thin line drawing.
Shapes drawn by using thick and thin lines
When you draw a curve, the thin line style is applied to the entire curve.
