What kind of cut is made vertically on a rafter, plumb to the building level?

The cut made vertically on a rafter, plumb to the building level, is known as a Plumb Cut. This type of cut ensures that the top of the rafter aligns properly with the roof line and provides a stable and secure connection to the ridge board or top plate of the building. The plumb cut is essential for achieving an accurate fit, maintaining the integrity of the roof structure, and allowing for proper load distribution.

The other options represent different types of cuts with specific functions: a Birdsmouth Cut is used to create a notch in the rafter to rest on the wall plate, a Bevel Cut is used to create an angled surface for connecting various elements, and a Framing Cut is a more general term referring to various cuts made in framing but does not specifically refer to a vertical cut made plumb to the building level. Understanding the purpose and application of the Plumb Cut is crucial for ensuring effective rafter installation in roof framing.
