Synopsis
Assembly Hole Features live as children of IvAssemblyDocument. Assembly Hole Features are specified through four major categories: Operation, Type, Placement, and Termination.
Hole Operation
Hole operation can be specified in one of four ways:
- Drilled - A default hole without countersink, counterbore, or spotface. No parameters need to be specified.
- Countersink - A conical hole cut into the hole face at the hole center.
- Counterbore - A cylindrical hole cut into the hole face at the hole center.
- Spotface - A cylindrical hole cut into the hole face at the hole center.
Hole Type
Hole type can be specified in one of three ways:
- Simple - A hole with no thread.
- Tapped - A tapped hole with parallel threading. The hole diameter is implicitly specified.
- Tapered - A tapped hole with tapered threading. The hole diameter is implicitly specified.
A parallel thread or a tapered thread may be specified for a hole. Since the threading dimensions are taken from a library of thread types/classes/designations, the diameter of the hole will, in these cases, be implicitly specified. If a parallel or tapered thread is not specified, the diameter can be explicitly specified; otherwise, it will default to 0.5.
Hole Placement
Hole placement can be specified in one of four ways:
- Linear - The placement of a hole on a face by its distance to two edges. A bias point that is in the same quadrant with respect to the two edges as the intended hole is required. This bias point must also lie on the face.
- From Sketch - The placement of holes by hole center points on a sketch.
- Concentric - The placement of a hole concentric with a circular edge or a cylindrical face.
- On Point - The placement of a hole by a work point and an entity that specifies the hole axis.
In assembly holes, any named entity (e.g. face, edge, etc.) must have an accompanying part. For example, in linear placement for an assembly hole feature, one must specify both edge1 and its containing part edge1Part.
