Add Bolt Pattern
A regular pattern of bolts can be applied to the slope face or upper slope face of a block with the Add Bolt Pattern option. The pattern location, bolt length, spacing, orientation, and offset from origin can all be defined by the user.​
To apply a pattern of bolts to the analysis:
- Select Support > Bolt Patterns > Add
- This will open the Add Bolt Pattern dialog.
- Select the desired Bolt Property. To add, edit, or delete Bolt Properties, select the Edit icon next to the Bolt Property dropdown.
- Select the Slope Face or Upper Slope Face as the Installation Face.
- Set the Orientation method as Normal to Selected Face or defined by Trend and Plunge values.
- Provide values for the Bolt Length and Pattern Spacing parameters.
- Enter the Offset from Origin. This can be supplied by horizontal and vertical values, or by selecting the location graphically on the model.
- Select OK to apply the Bolt Pattern.
- Repeat these steps to add additional Bolt Patterns.
The Bolt Pattern functionality is not limited to a single Bolt Pattern. Multiple patterns can be applied with different bolt properties, lengths, spacing, orientations, etc.
