ZW3D CAD Tips ( Modeling —— When you should regenerate the part history)

\The history of a part or assembly is very important to the part's integrity and to all other parts and assemblies that reference it.  There are a number of situations when regenerating the part history is strongly recommended. 

 

  • After editing dimensions
    You should always perform a History Regen after editing a dimension to verify the integrity of the active part. If the modification causes an error in the part's topology, you may select not to keep the changes and adjust the dimension modification accordingly. If you postpone the history regen an error introduced now will be more difficult to locate and correct.


 

  • After reordering features
    You can use the Cut, Copy and Paste feature commands to reorder features within the active part's history. Always perform a History Regen after reordering features to verify the integrity of the active part. If the reordering causes an error in the part's topology, you may select not to keep the changes and adjust the new order accordingly. If you postpone the history regen an error introduced now will be more difficult to locate and correct.


 

  • After suppressing features
    You should always perform a History Regen after suppressing features to verify the integrity of the active part. If an error in the part's topology is introduced due to other features being dependent on the suppressed feature, you may Undo the suppression. If you postpone the History Regen, an error that is introduced will be more difficult to locate and correct.
     

 

  •  Incrementally after editing
    You should always perform a History Regen incrementally after editing to verify the integrity of the active part. If the modification causes an error in the part's topology, you may select undo the changes and make adjustments accordingly. If you postpone the History Regen, an error introduced in an earlier edit will be more difficult to locate and correct.
