Subtract uses solid A to cut away from B, removing solid A and the overlapping geometry between the two solids - cut an opening in a curved surface much faster than using Intersect Faces.Quickly develop massing and void studies by splitting overlapping forms and choosing which pieces to keep and which to remove. Split breaks intersecting solids into pieces wherever they overlap without deleting anything.For example, analyze the volume of soil to be excavated for a building foundation by intersecting the building model with site topography. Intersect object A and B to create an entirely new geometry, object C. Intersect cuts two solids and leaves only the overlapping geometry.A great example, Trim lets you use the top plate of your wall to cut the birdsmouth detail in roof rafters. Trim uses object A to cut object B, but both objects remain in the model, so you can trim multiple objects using the same cutting object.

If you want to model precise objects like joinery or need to create complicated shapes from the combination of two (or more) solids, look no further than Solid Tools. Solid Tools make modeling intricate geometry a breeze - and they’re now included in SketchUp for iPad.
