Use Secondary Geometry representations to visually distinguish secondary objects from primary objects in accordance with commonly accepted industry standards.
Create Secondary Geometry representations to illustrate selected components in an assembly drawing as:
1) Primary Geometry - The objects of focus
2) Secondary Geometry - The background or reference objectsWith a drill, for example, the plastic casing is secondary–you still want to see it and know that it's there, but the moving parts are truly what you are concered with. Thus, the mechanical components are primary.
Toggle on the 'Secondary Geomtery' option in the drafting preferences.
If views are created prior to this preference setting, then you cannot specify the SG's in those particular views.
Specifying Secondary Geometry
You can specify the secondary geometry by following three ways.
I) Globally assign an object as secondary geometry
In the Drafting application itself, you can toggle on the 'Secondary Geomtery' option under the component properties from assembly navigator.
II) Specify the secondary geometry in Base View dialog
While creating the base view, you can specify the components as primary/secondary geometry components.
III) By 'Seconday Geometry in View' command
Menu > Edit > View > Secondary Geometry in View
With this command, you can redefine or update the SG specification in the selected views. You can select the view in which it is needed to specify the SG.
For any projected view created from a view in which SG is already specified, then projected views will also show the SG representation.
Secondary Geometry column in the Assembly Navigator
You can add the 'Secondary Geometry' column to the Assembly Navigator to identify the SG status of a component in the assembly.
(SG icons can be seen in the SG column within the drafting application only. If the application is switched from drafting to any other then SG column will not show the respective SG icons.)
The symbols that appear in this column indicate the secondary geometry status of a component.
Secondary Geometry - The component is globally marked in the drawing part as secondary geometry.
View Specific - The component's global secondary geometry status has been overridden in one or more views.
