Placing a Structure

Placing a structure, regardless of type, follows the same initial steps followed by configuration specific to your chosen structure type.

Placing a Single Mast Structure

Follow the steps below to place an STC, SSA or a Twin/Triple Cantilever


Step 1: Place a marker

Place a circle to act as a marker for the position you would like to place the structure.

Step 2: Click the 'Place' button in the 'Structures' section of the Lineardraft toolbar

This will open the 'Place Structure' window.

Step 3: Click the marker

This should be the marker you placed in Step 1.  A green tick will appear next to 'First marker' when complete.

Step 4: Right click anywhere on the screen

This indicates to Lineardraft that you are placing a single mast structure and moves to the next prompt.

Step 5: Click the left rail 

This should be the leftmost rail of the tracks you wish the structure to be associated with when looking in the direction of increasing distance/chainage. A green tick will appear next to 'Left rail' when complete. 

Step 6: Click the right rail

This should be the rightmost rail of the tracks you wish the structure to be associated with when looking in the direction of increasing distance/chainage. A green tick will appear next to 'Right rail' when complete.

Step 7: Click 'Place'

This will open the 'Edit Structure' window.

Step 8: Populate your structure details 

Name: Identifier for the structure.
Distance: This should be a chainage or distance value where the structure should be placed in kilometres, or your preferred unit of measurement.
Tag: This can be used for any tag or units you may want to add to the structure
Secondary (optional): Secondary chainage value, useful as a reference in projects which interface with additional chainage systems.

Step 9: Select structure type

From the drop-down menu, select your chosen structure type.

Step 10: Select mast type

From the drop-down menu select your chosen mast type. You can search for a specific mast and filter by design catalogue using the buttons at the top of the drop-down. Applying no filters means that masts from all catalogues will be visible.

Step 11: Configure mast

Adjust values for the Length, Bearing and RECOS/REFOS.

Length: Length of the mast in metres
Bearing: Rotation of the mast in degrees measured from North (0°)
RECOS: Distance from the centre of steel to the running edge of the closest rail in metres
REFOS: Distance from the face of steel to the running edge of the closest rail in metres

Step 12: Select foundation type

From the drop-down menu, select the type of foundation you would like to allocate. You can search for a specific foundation or filter by design catalogue using the buttons at the top of the drop-down. Applying no filters means that foundations from all catalogues will be visible.

Step 13: Configure adapter plate (if required)

Please note: If you aren't using a configuration which requires an adapter plate, skip ahead to Step 14. 

If you’re working with a mast and foundation combination which requires an adapter plate, the relevant fields will become available to you, as shown in the image below.

Select an adapter plate type from the drop-down and adjust the values.

Gap: Spacing between the top of the adapter plate and the base of the mast in metres 

Step 14: Configure foundation

Adjust values for the Gap, Top, Length and Bearing of your foundation.

Gap: Spacing between the top of foundation and base of the mast (or adapter plate if you are using one) in metres.
Top: Top of Foundation height above sea level in metres (by default this value will be set to the HRL).
Length: Length of the foundation in metres.
Bearing: Rotation of the foundation in degrees measured from North (0°).

Top tip: Clicking the 'reset' button associated with any of the above values, will reset the values to the default defined in your project settings

Step 15: Click 'Update Structure'

This will close the window and place the structure, which will be visible in both the 3D and plan views.
