The IPROHoles tool is used to create any type of normalized hole on the part. This dialog box is displayed every time you drop the IPROHoles tool on the part or when you edit an existing hole.
Description of the User Interface
At the top of the dialog there are the buttons useful to control the placement of the hole and a combo box used to select the Unit of Measure related to the parameter of the hole. At the left of the Unit of Measure combo there is a button that is used to display a list containing all the IPROHoles existing on the selected part. This list is very useful if you need to modify several holes at once. Clicking on the button, the dialog box will be enlarged, and the list of holes placed on the part will be displayed. At this point, selecting the hole in the list, the fields of the dialog box will be updated in order to reflect the values of the selected hole. A very powerful functionality of this tool is that, if you select an hole placed on a different part, this list will be updated in order to contain all the holes placed in the new selected part.
Components
The family of hole can be selected using the two tabs. When you change the type of the hole, the dialog box is immediately updated.
You can change the type of hole clicking one of the four option buttons placed under the tabs. Every time you change the selection, the dialog box is updated in order to show you all the parameters related to the hole.
Settings
The items included in this box enable you to save the current setting of the hole. This enables you to recall them quickly in future sessions. The buttons included in this section enable you to save, remove or apply any saved setting.
Parameters
- Type GAS - When this button is checked, a combo boxcontaining all the normalized GAS diameters becomevisible.
- Diameter - d or M - This option is used to select orto insert the required diameter for the hole. A label placed at the right of this item shows the Actual Diameter. In the case of simple hole, the Actual Diameter is the value of diameter minus the tolerance value. In the case of thread holes the Actual Diameter is the diameter minus the pitch.
- Hole Depth - L - This option is used to insert or toselect the depth of the hole. This option is disabled if you check the Through option.
- Bottom V - a - This option is used to control thebottom shape of the hole. This option is disabled ifyou check the Through option or the Flat option.When this option is enabled you can set the bottomangle of the hole.
- Hole Color - This option applies a color to the inside wall of the hole, it is available only for simple holes.
- Chamfer End - with this option it is possible to apply a chamfer on both edges of the hole (only initial, or initial and final if it’s through)
- Taper Angle - g - This option is used to set a taperangle for the hole. To enable this item, you have tocheck the Apply option.
- Drill Parts - If you check this option, the combobox Drill through Parts will be visible. Thanks to this combo, you can set how many parts to drill. Using this set you can “drill” several parts in asingle operation. Set the Drill Parts toggle button in order to generate the hole also over the parts that intersect the selected hole. The Drill Part toggle, became enable also if you set an Hole length bigger that the thickness of the selected part. In this way, setting the Drill Parts toggle, you can generate the hole also in other parts till to the desired length.
- Tolerance - If you check this option, a combo box containing the available tolerance will be displayed.
- Pitch/Thread for Inch - If you select a thread hole, these combo boxes allow you to select the type of thread for the current hole.
When you select a Counter Sink or Counter Bore hole, the section related to these parameters becomes visible.
The items contained in this section are used to set the diameter, the depth and/or the angle of a counter bore, counter sink or counter drill hole. Furthermore two buttons allow you to automatically load the Standard values defined for the hole.
When you select a Thread hole, the section related to thread parameters becomes visible.
The items contained in this section are used to define the Pitch of the thread, the length of the thread and the callout to set in the 2D drawing.
The data structure behind IPROHoles
All the data files related to hole are placed in the folder ..\Norme\Holes
This is the list of the files contained in the folder and a description of their structure:
Diameters.dat - Diameters_ENG.dat
These files contain the list of available diameters and their associated tolerances. Any row starting with the char # is considered as a comment. The row starting with the tag is used to define the label of the Tolerance available. All the values after the tag, will be inserted in the Tolerance combo box.

The first value of the row is considered as a valid diameter. All the following values are related to the tolerance values.
CDiameters.dat - CDiameters_ENG.dat
These files contain the list of the available diameters and depths related to counter depth holes. Any row starting with the char # is considered as a comment.

The first value of the row is considered a valid hole diameter. The second field is the Counter Bore diameter and the third is the Counter Bore Depth. Looking at picture you can see that if you set an hole diameter between 8 and 9, the CBore diameter will be set to 15 and the depth will be set to 8.5

The first value of the row is considered a valid hole diameter. The first field is the diameter of the hole, other fields are the standard pitch. The English definition of the file, is a little bit different. The first field is the diameter of the hole and the following are the Thread per Inches. Looking at picture you can see that for an hole diameter between 18 and 20, the Pitch1 is 1.5 and the Pitch2 is 2.5
