When creating an assembly drawing, it may sometimes be necessary to show certain components uncut (non-sectioned) in section views that appear on the drawing (see the following figure). Standard part components such as nuts, bolts, pins, etc. are commonly shown on a drawing in this manner. To accomplish this task, you can use the Unigraphics user-defined attributes functionality. By setting the user-defined part attribute called section-component to the proper setting, you can add components to an assembly that appear non-sectioned in section views on the drawing. You can also specify sectioning properties for individual occurrences of a component in a view with the Section Components in View option.
2）Non-sectioned Standard Part in a Section View
Creating non-sectioned components
Component parts added to an assembly, by default, are sectioned in section views on the assembly part drawing. You can make the components non-sectioned, by setting the user-defined part attribute section-component as follows:
Make the component part the work part.
Choose Format—>Attribute—>art.
Choose Assign.
Enter section-component as the title for the String Attribute and choose OK.
Enter no as the String Value and choose OK.
Choose OK to dismiss the Enter Title For String Attr dialog.
To check the existing part attributes perform the following steps:
Choose Format—>Attribute—>art.
Choose List.
Choose All User-Defined. An Information window reports the part attributes for the work part.
Note that once you add a component part to an assembly, all of its part attributes including the section-component attribute become object attributes in the assembly. This is true for each occurrence of the component added to the assembly. The following figure illustrates what happens when three occurrences of a bolt component are added to an assembly. Since each bolt component contains a section-component attribute set to no, all three bolts appear un-sectioned in the section view.
Three Bolt Components Added to an Assembly
Changing State From Non-sectioned To Sectioned Status
To change the state of a part from non-section to section status, you must delete the section-component part attribute. To do this, you must perform the following steps:
Make component part the work part.
Choose Format—>Attribute—>art.
Choose Delete.
Choose Menu User-Defined.
Choose SECTION-COMPONENT from the menu and choose OK.
Once the section-component part attribute has been deleted from the part, component occurrences of that part (in any assemblies) lose any object attributes inherited from the part attribute.
Changing the section-component part attribute value from no to yes produces the same result as deleting the part attribute. The components are allowed to be sectioned on drawings in their assembly parts. The preferred method however, is to delete the part attribute, since the default behavior in the absence of the section-component attribute, is to section the component. Leaving the section-component part attribute assigned to the part with a value of "yes" is unnecessary.
NOTE: When a section-component part attribute has been assigned to a component part, the solid bodies within the component part itself are not assigned this part attribute. This means that the solid bodies are sectioned in section views on drawings within the component part, regardless of how the section-component part attribute is set.
3）Overriding The Non-sectioned Component Status In An Assembly
Because each component added to an assembly contains its own object attributes, any of these attributes, including the section-component attribute can have their value changed individually. To change the section status of a component in an assembly from non-section to section, you change the value of the section-component object attribute from no to yes. The following figure shows one component in an assembly whose section status has been changed. To change the section status of a component in an assembly perform the following steps:
Make the assembly part the work part.
Choose Format—>Attribute—>Object.
Choose Assign.
Choose Variable Length Character.
Enter section-component as the title for the String Attribute and choose OK.
Enter yes as the String Value and choose OK.
Choose OK twice to get to the Class Selection dialog.
Choose the Type Filter Method.
Choose the Component object type and choose OK.
Select the desired component(s) to change, then choose OK and Cancel to complete the operation.
4）Changing the Section Status of a Component in an Assembly
To change the section status of a component in an assembly from section back to non-section, after its object attribute value has been overridden to yes:
Make the assembly part the work part.
Choose Format—>Attribute—>Object.
Choose Delete.
Choose By Title.
Enter section-component and choose OK twice to get to the Class Selection dialog.
Choose the Type Filter Method.
Choose the Component object type and choose OK.
Select the desired component(s) to change, then choose OK and Cancel to complete the operation.
To check a components existing object attributes perform the following steps:
Make the assembly part the work part.
Choose Format—>Attribute—>Object.
Choose List.
Choose the Type Filter Method.
Choose the Component object type and choose OK.
Choose the desired component(s) to check, then choose OK twice.
Choose All User-Defined and OK. An Information window reports the object attributes for the work part.
NOTE: Deleting the component object attribute that has not been overridden has no net effect on the object attribute. It has the same value as the part attribute at the component part level. 作者: duanxz 时间: 2002-7-21 11:27
