Choosing material, countersink size, and angle. This handout will focus on the standards of annotation for fasteners, and hole callouts (local notes). 1.1 symbols permit consistency in the way dimensions and tolerances are specified, and each symbol has a clearly defined meaning. If the specification of the manufacturing processes
For a symmetric part, it is only necessary to dimension to one side of the center line of symmetry. The purpose of a countersink is to allow a fastener, typically a flathead screw, to sit slightly below the surface of the part. Web a countersink hole is one in which the outer edge of the hole has been opened up to a conical entry.

How to make a break edge. I agree with your idea of using floating fasteners. Calling out a countersink in a drawing requires the 3 dimensions to be called out along with the appropriate gd&t symbols. At times, the break edge specification may be contained in the general tolerance block such as shown below.
In The Model Tree, Expand The Hole Feature, And Select The Note.
Web extracted to 2d drawings. Counterbored holes are specified by giving the diameter of the drill, the diameter of the counterbore, and the depth of the counterbore. Older blueprints may specify a counterbore with the notation cbore instead of the counterbore symbol. Many of these elements are notational in nature.
The counterbore symbol will often be used together with the diameter symbol and the depth symbol. Web waht is countersink callout. Choosing material, countersink size, and angle. Is this hole going into a flat surface? Web the gd&t callout for a counterbore is shown below.
