Solid Operation Types

Subtraction cuts out the shape of the Operator from Target.
Subtraction with upward extrusion cuts out both the shape of the Operator from the Target and its vertical projection from the bottom of the Operator shape to the top of the Target.
Subtraction with downward extrusion cuts out both the shape of the Operator from the Target and its vertical projection from the top of the Operator shape to the bottom of the Target.
Intersection keeps only the common part of the Target and the Operator.
Addition adds the shape of the Target to the shape of the Operator.
The solid operation affects the model shape, that is, the 3D view and the generated Section/Elevation/IE model and Detail Drawing view. Below is the Section view of the elements shown above. The Operators are shown in Wireframe, above, and their layers are hidden, below.
The Floor Plan view of both Target and Operator elements is unaffected. Putting the Operator element on a Wireframe layer does not affect its display. If the Operators’ layer is hidden, then they will not appear in the Floor Plan, but you will not be able to edit them until you make the layer visible again.
Note: If you select only the Target on the Floor Plan and display the selection in 3D view, the modified shape will be shown, but without displaying the Operator.
If you perform a Solid Operation on a Section/Elevation/IE view, you need to rebuild the window’s contents to see the results.
Net: takes any Solid Element Operations into account.
Gross: does not take any Solid Element Operations into account.
See Element Listing Parameters in the Interactive Schedule for detailed information on creating element lists.
