Holes

The IPROCentreHoles tool is used to create Centre Hole on the shaft part. This dialog box is displayed every time you drop the Centre Holes tool on the part or when you edit an existing Centre hole.

The Center holes can be placed only on cylindrical parts, drop the tool on an circular edge or face (otherwise you will be shown a warning message).

Components

You can change the type of centre hole by clicking a drop down button.

Holes

When you change the type of the hole, the dialog box updated the Norme text box.

In the status bar, it shows a warning message if the diameter of the hole is not compatible with the diameter of the shaft.

The data structure behind IPROCentreHoles

Every component defined in the User Interface has behind him some data files which contain properties and parameters related to the component itself. These files are placed in the folder of the standard rule. The main files associated to the family of components are the followings: CentreHoles.ini and *.uni

Every numbered section is related to an icon of the component in the User Interface, and every record contains these fields:

  • Type -> the number is related to icon of the component in the User Interface.
  • Table -> Data file Name of the Standard Rule.
  • Label -> Description of the Standard Rule in the User Interface.

This is the structure of a CentreHoles.ini file

# Type |   Table           |   Label
1       |   UNI3220A.UNI    |   UNI3220-A
2       |   UNI3220B.UNI    |   UNI3220-B
3       |   UNI3220R.UNI    |   UNI3220-R

The *.uni files, contain the fields of the standard values related to hole normative; the structure of the files are self-explaining.

This is the structure of a UNI3220A.UNI file
