The following is a description of the Opening Lines tab page of the Custom Settings Panel of Door or Window Settings, from the INT Archicad Library.
Use these controls to set the display of Opening Lines for each opening.
By default, these controls are grayed, because Opening Line display is set globally for all doors and windows in Model View Options.
For details on these settings, see Miscellaneous Settings for Library Parts.
However, to adjust Opening Line settings for this opening only, check the Override Model View Options box and set the options as needed.
Separate options are available for 2D Symbolic Display and 3D Projections.
The 2D & 3D Line Pen control affects the opening line display in both 2D and 3D.
