About Drawing Support for Inseparable Assemblies
Drawings support assemblies with embedded components similarly to support for regular assemblies. The following characteristics apply to drawings for assemblies with embedded components.
• A new drawing of an assembly with embedded components references the geometry of the embedded components. If a new drawing is created for an assembly after embedding or extracting the component, the drawing functionalities are fully supported for it.
• When a drawing already exists for the top-level assembly or a subassembly, and components are embedded or extracted, the drawing will retain detailing for these components such as hatching properties, annotations display, and layer status.
• When a View directly references a component being embedded, it will continue to reference the original component.
• Repeat regions do not include embedded components by default. You can include embedded components in a repeat region from the Repeat Region menu using the Incl Embedded attribute. Use the No Embedded menu command to exclude an embedded component from the repeat region.
Only embedded components marked as included in the repeat region, are included in the BOM.
• When embedding components in 3D model, if the Repeat Region attribute is set to Incl Embedded, then in the drawing environment names of the embedded components will be updated in Repeat Region as specified in the 3D model. Similarly, other attributes like Sorting are also retained and included in the Repeat region record for the embedded component. However, exception to this is: Comments, Dash Item, Fixed Index, and Filters. These attributes are not retained and need to be updated manually.
• When a BOM balloon is attached to a component that is embedded or extracted, then that BOM balloon will still be associated with the component after the embed or extract operation and vice versa.
Drawing Support for Replace Operations
• If an updated drawing is created for an assembly after performing a replace operation, the drawing functionalities are fully supported in the updated drawing.
• When a drawing already exists for the top-level assembly or a subassembly, and components are replaced, the drawing will retain detailing for these components such as hatching properties, annotations display, and layer status.
• When a drawing model is replaced, the old model name, with same id, is retained in a suppressed state in the drawing database. If the replaced model is embedded or replaced again, then drawing fails to retain some details of the replaced components as there are two models with same id in the database. Use the user command delete_duplicate_drawing_model ( > > 
Drawing Properties > ) to delete the suppressed model entry from the drawing database.
Drawing Properties > ) to delete the suppressed model entry from the drawing database.• If some components from an assembly are replaced and a drawing of that assembly is retrieved or switched, and if the drawing or assembly already has components with a name similar to that of the replaced components, then drawing may not retain the detailing of the replaced components.
• If the replace operation is performed with options like assembly containing model, reference model, interchange, module variant, and unrelated components then the drawing details may not be retained for the replaced components.
 | For Legacy Drawings: • To get drawing support for inseparable assemblies: ◦ For assembly drawings with embedded components, apply update drawing version 7162834 when you retrieve a pre-Creo 9 drawing. You can apply it using the enable_auto_drawing_update mechanism through config.sup. ◦ Apply update_drawing 7162834 after retrieving the drawing, then perform the embed operation in assembly. • To get drawing support for replaced by copy operations: ◦ For assembly drawings having replaced components, apply update drawing version 7162834 while retrieving a pre-Creo 9 drawing. You can apply it using theenable_auto_drawing_updatemechanism throughconfig.sup. ◦ Applyupdate_drawing 7162834 after retrieving the drawing, then perform replace by copy operation in assembly. |
Best Practices for Drawing Support for Inseparable Assemblies
• When retrieving an assembly drawing after embedding a component in an assembly, if the drawing is opened with > , the resuming views may not retain the detailing of the embedded components in all views, it will retain detailing of embedded components present in the first resumed view. It is therefore recommended to resume all views in a drawing before performing embed/extract operation in assembly.
• When retrieving a drawing with missing components it is recommended to first retrieve the assembly, use the Retrieve Missing Component command, available in assembly mode, to fix the assembly, and then retrieve the drawing.
◦ If Retrieve Missing Component command is used from drawing mode, and the retrieved component is having the same name as before then the detailing done for the retrieved component may get lost.
◦ If Retrieve Missing Component command is used from drawing mode, then the annotation positions in the retrieved drawing may differ from the source.
