Line Weights

Use the Line Weights dialog to define the width of the pen used to draw lines in views.

You can control line weights for model lines, perspective lines, and annotation lines.

For model lines, you can specify line weights for modeling components, such as doors, windows, and walls, in orthographic views. Line weight is dependent on the scale of the view.
For perspective lines, you can specify line weights for modeling components in perspective views. You may want to apply different line styles and line weights using the Linework tool. For more information, see Changing the Line Style of Elements.
For annotation lines, you can control the line weight of annotation objects, such as section lines and dimension lines. The weights of annotation symbols are not dependent on the scale of the design.

To assign line weights to element categories (such as walls, windows, and tags), use the Object Styles dialog.
