Some mid-point anchor (MPA) on gantry arrangements contain components that must be added as in-span equipment. To do this, just follow these steps.
If you have not yet added an MPA to your gantry, check out this article first.
Step 1: Click the 'Edit' button in the 'Wires' section of the Lineardraft toolbar
This will open the wire and structure selection window.
Step 2: Click on the wire you want to add the in-span equipment to and click 'Edit'
Alternatively, you can select your wire from the drop-down menu. You do not need to select a structure at this point. Clicking 'Edit' will open the 'Edit Wire' window.
Step 3: Click on the 'In-span equipment' tab
Step 4: Click the 'Add' button
This will open the 'Edit In-Span Equipment' dialog.
Step 5: Select the structure immediately preceding your MPA structure
This is so we can place the in-span equipment that precedes your MPA in the direction of decreasing chainage. In this example, ‘BD-11-27’ has been selected, as it immediately precedes the structure with MPA equipment attached.
You can either click the Locate... button and click on the structure in your design, or select the structure using the 'From Structure' drop-down menu.
Step 6: Select the in-span equipment you require
In this example ‘C99-E08’ has been selected as it is in the correct orientation for the arrangement being demonstrated.
Step 7: In the 'Distance' section, change the 'Ratio' value to '1.000'
This means the in-span equipment will be placed on the front of the MPA equipment.
Top tip: At this point you can also set the 'Status' of your in-span equipment using the drop-down menu at the bottom of the dialog.
Step 8: Click 'Apply'
This will close the 'Edit In-Span Equipment' dialog, and the equipment will now be visible in the 'In-span equipment' tab.
Step 9: Click the ‘Add’ button again
This will open a new 'Edit In-Span Equipment' dialog.
Step 10: Select your MPA structure
You can either click the Locate... button and click on the structure in your design, or select the structure using the 'From Structure' drop-down menu.
Step 11: Select the in-span equipment you require
In this example ‘C99-E08 (Reversed)’ has been selected as it is in the correct orientation for the arrangement being demonstrated.
Step 12: In the 'Distance' section, change the 'Ratio' value to '0.000'
This means the in-span equipment will be placed on the back of the MPA equipment. You can also select a 'Status' for your in-span equipment at this point.
Step 13: Click 'Apply'
This will close the 'Edit In-Span Equipment' dialog, and the second piece of equipment will now be visible in the 'In-span equipment' tab.
Step 14: Click 'Update Wire'
This will close the 'Edit Wire' window and place your two pieces of in-span equipment.
