Redefining the Ordinate Dimensions References
You can redefine the references of ordinate dimensions in the following ways:
• Right-click and select Edit Attachment on the shortcut menu to redefine the reference of an ordinate dimension in the ordinate dimension chain.
• On the Annotate tab, in the Edit group, you can click Attachment option and select the dimension to redefine the dimension reference.
 
• You can redefine the references of ordinate dimensions that were created as linear dimensions and later converted to ordinate dimensions.
• You can also redefine the reference of the dimension that you first created in the ordinate dimension chain.
• While redefining references, an error message is displayed when you select a reference that is not parallel to the ordinate baseline.
• You cannot redefine the references of multiple dimensions.
