ISO 10303-214:2010(E)
A Round_hole is a hole that is a removal of a volume of cylindrical shape from a solid part.
A Round_hole is a type of Process_feature_in_solid.
The data associated with a Round_hole are the following:
The bottom_condition specifies the Hole_bottom_condition that defines the type of the hole bottom.
See round_hole to hole_bottom_condition and round_hole to through_hole_bottom_condition for the application assertions.
There shall be exactly one object that defines the bottom_condition for a Round_hole.
The diameter specifies the Closed_profile_usage that defines the cross section of the hole in order to define the cylinder that is subtracted from the part. The Closed_profile_usage shall reference a Circular_closed_profile as used_profile.
See round_hole to closed_profile_usage for the application assertion.
The hole_depth specifies the Linear_path that is used as sweep path.
See round_hole to linear_path for the application assertion.
The taper specifies a shape variation to be applied to the Round_hole.
See round_hole to angle_taper, round_hole to diameter_taper, and round_hole to directed_taper for the application assertions.
The taper need not be specified for a particular Round_hole.
If present, there shall be exactly one object that defines the taper for a Round_hole.
