• What is the cause and solution for SAP error message ECLVIEWER028 - You must select two objects for a 3D comparison ?

  The SAP error message ECLVIEWER028 indicates that you are trying to perform a 3D comparison in the SAP Engineering Control Center (ECT) or a similar application, but you have not selected the required two objects for the comparison. This error typically arises in scenarios where a visual or data comparison between two 3D models or objects is necessary, such as in engineering or design reviews.
  Cause:
  The primary cause of this error is that the user has not selected two distinct objects (e.g., CAD models, drawings, or other 3D entities) for the comparison operation. The system requires two objects to perform a meaningful comparison, and if only one or none is selected, it cannot proceed.
  Solution:
  To resolve this error, follow these steps:
  
  
  Select Two Objects: Ensure that you have selected two different objects in the viewer or selection area. This can usually be done by clicking on the objects while holding down the appropriate key (e.g., Ctrl or Shift) to select multiple items.
  
  
  Check Object Compatibility: Make sure that the two selected objects are compatible for comparison. For instance, they should be of the same type or belong to the same category (e.g., both should be 3D models).
  
  
  Refresh the View: Sometimes, the interface may not update correctly. Try refreshing the view or restarting the application to ensure that your selections are recognized.
  
  
  Consult Documentation: If you are unsure about the selection process or the types of objects that can be compared, refer to the SAP documentation or help resources specific to the application you are using.
