A number of hole types are supported. They are identified
according to the evaluation of the Hole type attribute as follows.
Simple Hole
Simple hole is characterized by: |
- origin point and direction
- extension type identified according to the evaluation of the Hole
Extension attribute:
1 = blind
2 = through
- for blind holes, bottom type identified according to the evaluation
of the Hole bottom type attribute:
Flat Bottom
V Bottom.
- for V-bottom holes, bottom angle identified according to the value of
the Hole bottom angle attribute.
- the hole can be threaded.
|

|
Tapered Hole
Tapered hole is characterized by: |
- origin point and direction
- hole depth, diameter and angle
- extension type identified according to the evaluation of the Hole
Extension attribute:
1 = blind
2 = through.
- for blind holes, bottom type identified according to the evaluation
of the Hole bottom type attribute:
Flat Bottom
V Bottom.
- for V-bottom holes, bottom angle identified according to the value of
the Hole bottom angle attribute.

Counterbored Hole
Counterbored hole is characterized
by: |
- origin point and direction
- counterbored depth and diameter
- extension type identified according to the evaluation of the Hole
Extension attribute:
1 = blind
2 = through.
- for blind holes, bottom type identified according to the evaluation
of the Hole bottom type attribute:
Flat Bottom
V Bottom.
- for V-bottom holes, bottom angle identified according to the value of
the Hole bottom angle attribute.
- the hole can be threaded.

Counterdrilled Hole
Counterdrilled hole is
characterized by: |
- origin point and direction
- counterbored depth and diameter
- extension type identified according to the evaluation of the Hole
Extension attribute:
1 = blind
2 = through.
- for blind holes, bottom type identified according to the evaluation
of the Hole bottom type attribute:
Flat Bottom
V Bottom.
- for V-bottom holes, bottom angle identified according to the value of
the Hole bottom angle attribute.
- the hole can be threaded.

Countersunk Hole
Countersunk hole is characterized
by: |
- origin point and direction
- countersunk angle and diameter
- extension type identified according to the evaluation of the Hole
Extension attribute:
1 = blind
2 = through.
- for blind holes, bottom type identified according to the evaluation
of the Hole bottom type attribute:
Flat Bottom
V Bottom.
- for V-bottom holes, bottom angle identified according to the value of
the Hole bottom angle attribute.
- the hole can be threaded.

Please note that the Countersunk depth can be obtained by means of
the following formula:
Countersunk depth=(Countersunk diameter-Hole diameter)/(2*tan(Countersunk
angle/2))
Threaded Holes
The following attributes on the axial machinable feature allow you to access
threaded hole information (in the Search function, machining process
definition, machining operations that require thread information, and so on).
- Threaded: True or False
- Thread diameter (length value)
- Thread depth (length value)
- Pitch (length value)
- Thread direction:
0 = Right-threaded
1 = Left-threaded.
The attribute values are read from the design threaded hole (that is, as
specification).
