Hi,
When designing symmetry is one of your best friends. We want to work Smart and not Hard.
If you have a design that is totally symmetrical in one or more planes then the easiest way is
to simply model the bit you want and then at the very last moment use the Mirror command
to complete your model. An example of this would be the way many of the users who model
Boats and/or Aircraft. Either model is typically very highly symmetrical so they simply model
half of it and at the last moment Mirror it. Then it is a simple job of finishing the model by
adding the stuff that is non-symmetrical. Boats for example might only have a deck hatch on
one side.
When using this technique in a practical way there will always be Components, Assemblies
and Sub-assemblies that you WANT to be symmetrical no matter what. These will be the
Parts that you would Copy/Paste, although the Mirror command is better. Then you have
a whole bunch of Parts that are NOT Symmetrical you add. You don't have to change your
Workflow to get what you want. Careful management of the Timeline and logical creation
of your model should be enough to achieve what you want.
The Copy/Paste command will work fine if you have a whole bunch of boxes that you want
to Cookie Cut in rows and columns. If you want Symmetry then Mirror is the Tool you want
to use.
Cheers
