The Edit Bolt Pattern option (End Support) allows you to edit a bolt pattern which has been added to the ends of the excavation.
You can edit the pattern parameters such as bolt length, spacing, properties.
You can also edit the location of the pattern.
Note that it is not possible to edit individual bolts in a pattern. Pattern bolts can only be edited as a group. All bolts will have the same properties, length, spacing etc. If you require different bolt properties for certain bolts, you will have to use the Spot Bolting option.
To edit a bolt pattern on the ends of the excavation:
First, make sure you are viewing the End Support Design view (select the End Support Design View button from the toolbar).
Select the Edit Bolt Pattern option from the Sidebar or the Support menu, and you will see the Edit Bolt Pattern dialog. (Note: since there can only be one bolt pattern on the ends of the excavation, it is not necessary to select the pattern in order to edit it).
TIP - you can also right click directly on any bolt in the pattern (i.e. the grid of points displayed in the End Support Design view) and select Edit Bolt Pattern from the popup menu.
In the Edit Bolt Pattern dialog, you can edit the bolt length, spacing, or assign a different bolt property type. You can select the Apply button to view the results of changes (e.g. changing the pattern spacing) without closing the dialog.
You can also change the installation point of the pattern (i.e. shift the pattern location) from the Edit Bolt Pattern dialog, as follows:
Select the Adjust Installation Point button in the dialog.
The dialog will close, and the current installation point of the pattern will be highlighted by a cross-hair icon.
To graphically adjust the installation point - hover the mouse over the point, and the cursor will change to a 4-way arrow symbol. When you see this, you can click and drag the installation point to a new location. As you move the point, the pattern location will be interactively updated on the screen. When the pattern is in the desired position, right click and select Done, or press Enter, and the updated pattern will be applied to the model.
Or you can enter the x-y coordinates of the new installation point in the prompt line. When you press Enter the updated pattern location will be applied to the model.
Remember, if you made a mistake with the editing, you can always just select Undo to restore the original pattern.
