CE - Smart model (primitive) becomes Parametric model after cut

Question

Why does a smart model become a parametric model after a cut is used?. 
 I received this issue from our Academic user base.... 
 If I create a Primitive solid (cube) in CE. I then place a shape to use as a cutting profile. Cut the solid and end up with what I would expect. However, if I look at the properties of this model , it has changed from a smart solid to a parametric solid. WHY? 
 If I then open this in ABD V8i, promoting it to an ABD part. ABD reports that this is an &ldquo;extended element&rdquo; - WHY? 
 
 How can I use a solid between CE and V8i? 
 How can I stop a smart solid from changing to a parametric solid? 
 What does 'Extended element mean?

Ian, 
 To use element between this 2 versions you should get to use only primitive solid or smart solids. 
 After we create some difference and you get a parametric element you can drop the "application element" and get as result a "smart solid" 
 Extended element in V8i is an element created with a superior version than V8i.

ABD reports "extended element" because it is still base in V8i technology. 
 
 Hope this helps.

 As Jose mentioned the solid will be visible in both versions but a parametric solid will show as an extended element.

 You can certainly do as Jose suggested in dropping the element. You can also make sure not to use the tools that will result in a solid being upgraded to a parametric solid. 
 
 Most likely the tool above was used, you can visually see that it has options that support use of variables. The default ribbon when in the Modeling workflow uses the new Parametric Feature tools, when these are used the solid will be upgraded to a Parametric. You can compare the above to the old "Cut Feature" tool: 
 The old Feature tools are available to use they can be found under toolboxes "Legacy Create Feature" or "Legacy Feature Modeling," Also if in the Task Navigation workflow they are found under "Feature Modeling"
