Setting Class Properties
Once created, the classes display on the Classes tab of the Organization dialog box, where various properties can be set and edited.
 
1.
Select Tools > Organization. Alternatively, click the Classes button on the View bar.
The Organization dialog box opens.
2.
A list of the current classes in the drawing displays. Depending on which view option is selected at the top of the dialog box, either details or visibilities of the classes display. The visibility of classes in the drawing area and the active class can be changed in Details view. The visibility of classes in viewports and in saved views can be changed in Visibilities view (see Setting Visibilities).
3.
4.
If desired, enter a new name for the class in the Class Name field. Then, set the graphic attributes of the class. See Setting Class Attributes for more information about graphic attributes.
 
Applies the attributes displayed in this dialog box when creating an object assigned to this class. If Use at Creation is not selected, these attributes can be applied to the object later by assigning the Class Style from the Attributes palette. See Setting Class Attributes for more information.
Applies a patterned fill and color to objects in this class. Click the pattern box to select the desired pattern, and then select the foreground color and background color from the color boxes next to the pattern.
Applies a hatch to objects in this class. Select the desired hatch from either the default resources or the current file’s resources (see VectorWorks Fundamentals Default Resources). Select Hatch from the list to create a new hatch to apply to the class.
Applies a gradient to objects in this class; click the gradient preview to select a gradient resource from either the default resources or the current file’s resources (see VectorWorks Fundamentals Default Resources)
Select the line style and thickness for the class; to use a custom thickness, select Set Thickness from the line thickness list to access the Set Thickness dialog box
Select the marker style for each end of lines, dimensions, arcs, polylines, 2D polygons, or freehand lines in this class. Choose the marker style from the list of available markers. To use a custom marker style, select Custom and specify the marker settings, or select Edit Marker List from the marker style list to set the available marker types (see Setting Default Marker Types).
When the Quartz (Macintosh) or GDI+ (Windows) imaging VectorWorks preference is enabled, specifies the class transparency; drag the slider to the left to increase the transparency, or enter an opacity percentage in the box to the right of the slider
If there are saved views in the drawing, opens the Saved View Visibilities dialog box. Set the visibility for the new class(es) in the saved views (Visible, Invisible, Gray, or Don’t Save). See Setting Visibilities.
If there are viewports in the drawing, opens the Viewport Visibilities dialog box. Set the visibility for the new class(es) in the viewports (Visible, Invisible, Gray, or Don’t Save). See Setting Visibilities.
5.
Click OK to return to the Organization dialog box. If objects in an edited class already exist in the drawing, and the class is set to Use at Creation, when prompted, specify how to apply the changes to the existing objects.
6.
Click OK from the Organization dialog box to save the changes.
If multiple classes are simultaneously selected for editing, and some are set to apply attributes while others are not, Use at Creation appears dimmed, indicating an unknown setting. Additionally, if some or all of the attribute values are different for the selected classes, the editing fields for those values indicate that the value is unknown. When the OK button is clicked, the currently defined settings shown are applied to all of the selected classes. Any information with an unknown setting is not applied.
Setting Class Attributes
There are two types of attributes available for each object: class attributes and object attributes. Class attributes represent the graphic attributes information assigned by the class. Object attributes are assigned directly from the Attributes palette. The attributes that an object uses when it is created are controlled by Use at Creation in the Edit Class(es) dialog box.
When Use at Creation is selected for a class, objects created in that class or subsequently assigned to that class use the class attributes. The Attributes palette displays an arrow to indicate that the attributes have been set by class. If objects in that class already existed before Use at Creation was selected, you are prompted to decide how to apply the attributes to the existing objects.
Class attributes can be overridden by selecting the object(s) and applying the attributes directly from the Attributes palette. Later, class attributes can be selected again from the Attributes palette by selecting Class Style from the attribute list. If Use at Creation was not selected for a class, selecting Class Style for an attribute applies the class setting to the object(s) at that time.
For more information, see The Attributes Palette.
