General Settings
Type Used to select the general object type, for example, sphere, ellipse, rectangle, or other type.
For more information on the different object types, see Non-sequential Objects , Non-sequential Sources , and Non-sequential Detectors .
Data File If the object type is defined by an external file, such as a polygon object, the file name may be selected here.
User Defined Aperture If selected, a user defined aperture (UDA) file will be used to define the extent of the object. Not all objects support this feature. User defined apertures (UDA) may be placed on some NSC surface objects. The UDA file must be placed in the <objects>\Apertures folder (see "Folders"). UDA's are defined exactly as described for sequential surfaces, see "User defined apertures and obscurations".
File If a user defined aperture is selected, the name of the aperture file may be selected from this control.
UDA Scale The UDA Scale is a dimensionless multiplier that scales the aperture defined in the UDA file.
Edit User Aperture This button will invoke a text editor to allow user editing of the selected UDA file. The UDA file needs to save and the object reloaded to make the changes effective.
Row Color This control chooses the color of the row in the NSC Editor for the object. By default, objects made of glass, "MIRROR", or "ABSORB" material, as well as sources and detectors are color coded. Any object may use either no color, the default color, or a user defined color. The coloring of rows may be disabled, see the "Editors" section of the OpticStudio Preferences.
Use Global XYZ Rotation Order If checked, the rotation convention for object tilts is to first rotate about the X axis, then the Y axis, then the Z axis. If unchecked, the rotations are done about the Z axis, then the Y axis, then the X axis. This latter ZYX convention is what a sequential coordinate break surface does if the order flag is zero. Note that rotating using the ZYX convention is exactly the same as rotating about the X axis, then rotating about the "new" Y axis, then finally the "new" Z axis. See also, the "Coordinate system" explanation in the Object Placement section.
