NPT Holes

The IPROHoles - NPT Holes tool is used to create NPT Hole (National Pipe Thread) in the scene. This dialog box is displayed every time you drop the NPT Holes tool in the scene or when you edit an existing NPT hole.

Settings

Holes 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

Holes Parameters
  • Normative - This option is used to select the standard diameters in inches or millimeters.
  • Hole Diam. - This option is used to select the required diameter for the hole.
  • Hole Depth - This option is used to insert or to select the depth of the hole. With the option at right you can see the measurement in inches or millimeters.
  • Taper Angle - This option shows the draft angle of the hole.
  • Thread Pitch - This option shows the Thread Pitch of the hole. To enable this item, you have to check the Edit option.
  • Callout - If you want assign the callout in the 2D drawing, check this option.
