Stack Planning

The basic idea behind the stack module is to enable the user to stack their elements so that these stacks can be prepared to be loaded onto a truck.

The Stack Planning module enables the user to define how the elements are to be stacked. The elements may be stacked either on a:

Stack

  • A free stack that needs no previous settings

Predefined Stack, referred to as a Stack Template (recommended)

  • A stack that is set up in the Resource Manager settings

Before this article dives into how the elements get placed on the stacks do, we first need to set up the needed stack templates – All the settings for the stacks are done it the Resource manager. It should also be decided if the stack and transport module should be shown with a 3D view or not and how the default settings for the stack status should be:

Stack Settings

Stack Template Settings

Stack in Project Manager

Before the stack module can be used is it necessary to activate the module in Project manager. This is done under the tab “Modules”.

After activation of the module will the stack planning window be active. This window is divided into 2 or 3 areas (3 if “Use visual stack” is set to “Yes”):

  • General stack information (1)
  • Stack element information (2)
  • 3D Model of the stack (3)

General stack information

The General stack information contains the list of all the created stacks in the specific project. Besides showing all the general information about the stacks is it also possible to set up different filters, settings for the 3D view, and even create stacks and add the stacks on transport in this part of the stack module.

1590589302667-453.png

The following information columns for the stacks can be shown in the grid:

Stack Centroid X (Only used for Visual) – The center of gravity in X-direction for the rack itself

Stack Centroid Y (Only used for Visual) – The center of gravity in Y-direction for the rack itself

It’s possible to customize the layout of the columns and any column can be shown or hidden by right-clicking on the column header. In the right-click menu is it also possible to freeze the column layout, use “Freeze/unfreeze columns” to freeze/unfreeze all the columns to the left from the selected column. The frozen columns will be fixated when scrolling in the grid.

Stack element information

The stack element information area shows all the elements on the selected stack. Within this area is it possible to modify the placement (stack layer / Placement No X) of the elements no matter if “Use visual stack” is “Yes” or “No”.

1590589719325-769.png

The following information columns for the stacks can be shown in the grid:

Stack Layer No – Shows the layer placement of the element – Each stack/rack type have its own layer definition (See the different stack/rack type for more information about layer placement)

Stack Sequence No – The sequence of the elements should be placed on the stack.

Placement NO X – The placement of elements in the same layer.

Just like the General stack information columns is it possible to customize the layout of the grid.

The icons at the top allow the user to modify the elements on the stack:

Cut selected elements (9)

Allow the user to cut the selected elements between stacks.

Delete selected elements (10)

3D Model of the stack

This area shows a 3D model of the stack and the elements on the selected stack. In the 3D view is it possible to move the elements manually by drag and drop – This makes it possible to find tune the placement of the elements.

If the moving element is placed outside the stack will the element be shown as red – This is a warning to show the user that the element is outside the stack.

1590591235319-491.png

A clash between two elements will be shown as pink to warn the user about the clashing elements.

image-20200527161849-39.png

The bounding box of the elements in the 3D view is based on the total element measures (Total Length, Total Width, and Total Height – For more information about this, click on this link) and the fine-tuning of the element placement could, therefore, result in some pink elements. The picture below shows a good example of when 2 elements are shown as clashing but isn’t. It’s therefore important to use common sense together with the warning system.

1590591249366-870.png

When moving the elements manually in the 3D view is it also possible to merge the elements into the same Stack layer.

Before moving the elements into the same layer in the 3D view:

1590591289188-224.png

After moving the element in the 3D view:

1590591297057-354.png

Besides moving the elements in the 3D view is it also possible to remove the elements from the stack by right-clicking and selecting “Remove marked elements”.

1590591308462-227.png

After the warning will the element be removed from the stack.

1590591316324-440.png

1590591320596-856.png

It’s also possible to change the stack Sequence No of the elements in the 3D view. This is done by selecting the elements in the stack sequence order and selecting “Set stack sequence no” in the right click menu.

image-20200527161849-46.png

The new stack sequence order is based on the selection order when marking the elements.
