Add Bolts

The Add Bolts option is used to add bolts to a model.

To add bolts:

1. Navigate to the Loading & Support workflow tab
2. Select: Support > Add Bolts
3. You will see the Add Support Pattern dialog.
4. Select the Support Property. See the Define Bolt Properties topic for more information about bolt properties.
5. In this dialog, you can define the bolts using the following tabs:
   • Shape
   • Properties
     
   • Surface
   • Location

Shape

Define the bolt pattern shape:

• Rectangle
  • Width and Height
  • Basepoint [default (U, V)= (0, 0) or custom; point of reference used to translate (U, V) coordinates to (X, Y, Z)]
• Circle
  • Radius
  • Basepoint [default (U, V)= (0, 0) or custom; point of reference used to translate (U, V) coordinates to (X, Y, Z)]
• Polygon (use table to enter custom coordinates)
  • Coordinates [U and V]
  • Basepoint [default (U, V)= (0, 0) or custom; point of reference used to translate (U, V) coordinates to (X, Y, Z)]

Properties

Define the bolt length, bolt orientation, and pattern spacing:

• Bolt Length: the length of the individual bolt in the bolt pattern
• Pattern Properties
  • Horizontal Spacing
  • Vertical Spacing
  • Pattern Angle
  • Pattern Offset: pattern offset from Basepoint (U, V) defined in Shape tab
• Orientation
  • Vector
  • Trend/Plunge
  • Normal
  • Local +x
  • Local +y
  • Local +z

• Staging: if your model is staged, you can specify the installation and removal stage of bolts.
  • Install at stage - by default the installation stage will be set to the stage that you are currently viewing (i.e. the currently selected stage tab). You can enter a different stage if necessary.
  • Remove at stage - by default the removal stage will be set to never. You can enter the stage at which the Bolts are to be removed (uninstalled), if applicable.

Surface

Define where the bolt pattern will be placed on the model (which model entity will be affected by the support placement):

• Projected on Terrain
  • Spacing Mode (Orthogonal to Drilling Direction or Along the Surface)
• Projected on Volume
  • Volume
  • Projection
  • Spacing Mode (Orthogonal to Drilling Direction or Along the Surface)

Location

The options here allow loads to be either placed freehand on the model using the Freehand Manipulation commands or defined by X and Y coordinate on the modelling interface.

• Freehand Manipulation: these commands will minimize the Define Load dialog and allow the user to place the load "Freehand" on the model.
  • Move Load: move the mouse around the modelling interface and click to place the load in the desired location.
  • Rotate Load: move the mouse to rotate the orientation of the load, using the center as the base.
• Numerical Definition:
  • Location: Enter X (m) and Y (m) coordinates to define where the basepoint (previously defined in the Shape tab) of the load will be located on the model.
  • Orientation: Enter an Angle to finalize the load definition.
