One day, you receive an imported part model as below.

Most of the time, we are require to do some modification on the model; it could be the model shape, dimensions of the model or even add some features on the model. Say if the model/part is symmetry, the best practice is to
“Reduce a Part to its Smallest Repeatable Symmetrical Body”
How can SolidWorks help you to do this in the fastest way? By using the SolidWorks Utilities add-on, launch the Symmetry Check tool (Tools > Symmetry Check…).
Then, use the Automatic symmetric split,
The model will be split instantly with split lines.
It doesn’t care the orientation of the part and therefore this is great to be used for imported file or use for simplified the part for simulation purpose.
