Holes
The Holes 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 Holes 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 buttons included in this box allow you to save the current hole settings. This allows them to be quickly recalled in future sessions. From the combo box you can select saved holes, while the button on the right allows you to open a dialog box for managing and reordering settings (which are separate for plain and threaded holes).
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.
- Pitch Thread Coarse/Fine - If you select a threaded hole, this combo box allows you to select the pitch type.
- Tolerance - If this option is selected, a combo box containing available tolerances will be displayed.
Hole Depth - L - This option is used to insert or select the depth of the hole. This option is disabled if you check the Through option.
- Through - If this option is selected, the hole goes through the entire part from the selected face to the opposite face.
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.
Taper Angle - g - This option is used to set a taperangle for the hole. To enable this item, you have tocheck the Apply option.
Hole Color - This option applies a color to the inside wall of the hole.
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)
Drill Parts - If you select this option, you can “drill” multiple parts in one operation. In this way, you can generate holes even in the parts below the first one, up to the desired length. If, you also enable Through opt. the Drop-down menu Drill Parts will also be visible, from here you can set the number of parts to be drilled; which will generate as many through holes in the selected parts below.
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 Holes
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:
The data files can edited also with the Library Data Manager application.
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 Toll is used to define the label of the Tolerance available. All the values after the Toll tag, will be inserted in the Tolerance combo box.
