We have a part that we want to change into several parts.
Than we go to insert, features, split.
On our left side a property manager appears
Than we select the elements that will be used as a split tools. The face and a 2D sketch.
In the preview we can see that we have 3 bodies.
In the property manager we check all 3 bodies.
If we click OK we can see that we have created a multi bodies. We can see in the design manager tree under the folder solid bodies.
If we edit this split feature and we click on auto assign names and we check copy custom properties to new parts.
Than a small window appears asking you to browse to save these newly created parts
This way you are putting in the same folder these new parts and you are giving them the names that you want
When you open the folder you see your new parts created from one part.
