The Line of a geometry refers to the outline, level delineation, and verticals.

Some line style settings only apply in 2D (top view).

Change a line color by selecting a preset.

Opacity controls how transparent the lines are.

Adjust the value between 0% and 100% in the number slider.

Some line styles only affect unenclosed lines or 2D polygons(ones with no height or floor to floor/levels).

Line width controls how thick the line appears in 2D (top view).

Adjust the number slider to set a width in pixels.

Dash controls the line style. Choose a preset, including solid or multiple dash styles.

To customize the Dash style, switch to "All" properties mode.

Type a dash pattern into the box, comma separated.

The pattern applies a series of dashes and spaces - in dash, space order. The pattern always repeats.
