What is the purpose of the additional listing for the extruded "Plate Bottom", "Plate Bottom Dado" & "Plate Top Dado". There are only two parts for each plate system and you can uncheck the one listed last and it does not shut off either of the first two listed.

The tree only has the extra listing for any extruded parts labeled "Plate". The nailer I have showing consists of five individual parts and each one, when unchecked turns off.

I haven't found the answer in the many documents on the "Knowledge Base", regarding the use of "solid Modeling".

I thought it has to do with setting "Apply Machining" to "True". However, the "Plate Bottom" is set to "False" and it shows the additional "Plate".
