1. Purpose of the tool.

The Wall Trace Tool is designed to assist in the configuration and insertion of scaffold perimeters. Key features include:

• Purpose and Benefits: The Wall Trace Tool allows users to create accurate scaffold perimeters by tracing walls, providing flexibility in design and ensuring that the scaffold aligns with the intended structure.
• Configuration Options: Users can configure various options before insertion, such as adjusting the length and geometry of the wall trace, which enhances the modeling process.
• Hierarchy Management: The tool incorporates a hierarchy system that allows users to access and modify different levels of the scaffold design, including bays and scaffold components. This flexibility enables efficient adjustments and modifications.
• Direct Modification: The Wall Trace Tool supports direct modifications, allowing users to change the length and shape of the scaffold perimeter easily.

2. User Interface overview.

The tool is located under the Scaffold Modelling tab.

To open the tool menu please double click on the tool.
The tool contains following features:

Layout Tab Wall Trace supports both closed and opened layouts, the user can select between Closed Layout or Opened Layout to choose the configuration that best suits their project needs.

Corner arrangements Tab refers to a specific configuration, these set of parameters allow users to create very specific corner arrangements for scaffolding for both Outer and Inner options. 

• Type 1 – Perfect corner: this will create an exact corner bay based on the width of the scaffold boards butt together without the need to overlap, this will also adjust adjacent bays and add additional lapping bays where required
• Type 2 – Adjust corner bays: bays will be shortened and lengthened to accommodate the corners creation, the order in which the bays are selected determine which bay are extended and shortened with the first pick being the priority.  Again lapping bays will automatically be created where bays are moved apart from each other
• Type 3 – Adjust corner bays without corner standard: as type 2 but the inner standard removes and the inner ledger from priority bay 1 is used as a support for the perpendicular by and deck
• Type 4 – Lapping bay at corner: this option creates a fly past corner and additional overlapping deck/board elements are created to fill the gaps between the bays, the order in which the bays are picked again determines which bay passes the other  (Only available for outer corners)

Lapping Bay Rules

• Bays must be perpendicular
• Picking order of bays (first and second picked) determines the order on how the corner is generated (first pick is priority element)

Lapping bay configuration Tab allow users to effectively manage and customize the lapping bays in scaffolding designs users can insert lapping bays at inner corners for two perpendicular bays. This feature is available when the Outer Guardrail option is set to "Tube (at corners)" at a corner bay.

• Lapping plank length: the system can automatically adjust settings for lapping bays, making it easier to manage configurations without manual input or you can manually select from 1.0m, 1.5m, 2.0m, 2.5m
• Lapping plank width: this is a set value by default of either 0.3m/0.2m and select the appropriate width mased on the bay to be placed onto.  This can be overridden to force a single value of 0.2m or 0.3m if required.
• Tube Length: the system allows for adjustments to tube lengths, ensuring that the components fit correctly within the lapping bay structure again this can be automatically assigned or manually overridden with values ranging from 0.3m to 6.0m
• Creation of bottom inner tube: this provides additional structural support using the aforementioned parameters to the inner standards at deck level selected during the Lapping Bay creation.

Bay Configuration Tab contains drop downs for dimensional constraints of the Bay, you are guided for length and height by the scaffold system manufacturers values, then manually input top platform height and building offset requirements.

You can also control the Platform Lift Heights by manipulating the Up/Down arrow to move in increments of 500mm.

Standards Tab allows greater control on how bay configuration is implemented. 

The main driver is the Size parameter that allows ScaffPlan to automatically choose Standard Lengths or alternatively specify a specific length from the system manufacturers range that may be required for design or availability reasons 

Top and bottom end also can be specified to form more bespoke bay configurations, these include;

• Open
• Spigot (Top End only)
• Head Jack
• Baseplate

The Rotation parameter controls the direction of the Top and Bottom end configurations.

If the Bottom extension type is set to Custom an additional Input parameter becomes available to specify a user input value

Sole board Tab defines the material Type and Arrangement

For Type:

• Timber 
• Steel
• None

For Arrangement:

• Single
• Triple

Ledgers/Transoms Tab are created on a Bay specification basis but can also be manipulated further in the model if required so ensuring you have a good specification platform where minimal editing is needed later on in the model, so picking between the options available in the drop-down menu can help achieve this early on in a project.

The main options are either;

• None
• Ledger
• Transom

Guardrail Tab are created on a Bay specification basis but can also be manipulated further in the model if required so ensuring you have a good specification platform where minimal editing is needed later on in the model, so picking between the options available in the drop-down menu can help achieve this early on in a project

For the Inner and Outer parameters you have the option of:

• None
• Ledger 
• Tube (at Corners)

For the Inner Top and Outer Top parameters you have the option of:

• None
• At 1m (Inner Top only) 
• At 1m and 2m (Outer Top only) 

Bracing Tab can initially be placed on creation and you can control the direction and the faces of the bay to where is applied and the lift between levels where it is included

The direction can either be Right-to-Left or Left-to-Right, and you can choose the following positions

• Inner
• Outer
• End 1
• End 2

Top Ring Tab provides an option for creating and controlling the top ring in a bay configuration extending the inner and outer standards to a common level and closing off with ledgers to all sides

Console Bracket Tab it is possible to add console brackets at one or both ends of a bay and to the inner and outer faces of the bay, you can quickly setup arrangement for different bay configuration for mid and end bay types and save for future use.  Additional options become available depending on where you specify Inner and Outer console bracket instances.

Depending on the system you are using the selection available to you will vary, below is an example showing some of the U-Layher console bracket sizes.

Additional information is available for the Planks inside (at corners) for greater clarity on the parameter setting 

Wall Ties Tab allows for easy insertion and direct modification of wall ties within the scaffolding model.  Users can quickly create and change wall tie types as needed to fit the design specifications though the Wall Trace Tool and allow for automatic placement based on their design option and specified arrangement settings  

• Tube location: users can choose where the Wall Ties are positions to the Left or Right side of the associated standard or tube
• Type: users have the option of a Single Leg which is particularly useful in situations where space is limited or when a lighter anchoring solution is sufficient or a Double Leg where additional strength is required, such as in high-rise scaffolding or when working with heavy loads.
• Horizontal: you can determine the tie pattern in the horizontal direction to include a wall tie in this direction to Every Leg or alternatively every 2^nd or 3^rd leg spacing.
• Vertical: you can determine the tie pattern in the vertical direction to include a wall tie in this direction to either every 2m or 4m in relation to lift heights. 
• Tie Ends: this provides additional tie creation at the end bays standards locations using the parameters set in the Horizontal and Vertical drop-down settings

3. Tool dialogue buttons.

No.	BUTTON	FUNCTIONALITY
		To save a current tool setting it is required to type name of the setting into the box and click Save button. To load previously saved settings please click on the box to drop down a list of setting s available then choose a desired setting. Once the setting clicked from the drop-down it will be automatically loaded, and dialogue boxes updated to values saved under the setting.
		Opens ScaffPlan knowledge base articles on the tool usage.
		Prompts to create scaffold line by tracing points in the model or over a references model.
		Saves values set in the dialogue boxes without closing the dialog box. ScaffPlan uses these properties the next time you create an object of this type.
		Modifies the selected wall trace using the current properties of the dialog box such Type, Subtype, Name etc. as set in the tool.
		Gets properties from the selected wall trace tool in the model and fills the menu with the values of the selected wall trace. If several wall trace tools are being selected, ScaffPlan takes the values from the first one selected and updates the dialogue boxes.
		Switches all check boxes in the dialog box on and off. Used when all boxes need to be unticked then some only need to be ticked (taken into effect) once the Modify button is pressed after.
		Closes the tool menu without saving the properties or modifying objects.
