Changing the block area and description
When a block is predefined at the main site, the block name, block area, and description are set. These values can be modified later in System Management > Projects > Building Block Overview.

This is the same function as Tools > Information > Building Block Overview function in the 2D-Contek and 3D-Contek applications, but with the extra functionality to modify the settings of each block. You can set the block name, define the block area, set the default grids, and add a description. You can also predefine blocks.
The blocks that will be affected by the changes need to be checked out. The system will automatically try to check out the predefined blocks, if needed.
Important: Only one user at a time can access this function with full access. Meanwhile, other users will not be able to open a block or a drawing in the project. Furthermore, this function cannot be opened with full access if another user has accessed the Block Groups, Block Order, Quick Block Definition Tool or Reassign Blocks to Groups function.
Note: This function opens in read-only mode, if System Management has been started in read-only mode. For more information, see Accessing System Management.
-
Block group – Name of the block group that is open.
Note: A group name can only consist of alpha numeric characters. It must not contain spaces, and it cannot be named Cancel or All. Group names are not case sensitive.
-
Block name – Name of the block that is open.
Note: Blocks named as 99999 and 12346 can only be opened in the 2D-Contek application.
-
Description – Description of the building block.
-
Read-Only – Changes the selected block to read-only. This setting can only be changed from the System Management application. And then also only when the selected block is checked out to the current site.
-
Area – The minimum and maximum values for the length, breadth, and height of the currently selected block area.
-
Construction area – Displays the length, breadth, and height values of the construction area.
-
Default grids – Shows the direction of the default grids.
Note: Using a width grid whose direction is towards the port side is not reflected in the presentation of the breadth (width) values here. The system always shows the minimum (port side) values as negative and the maximum (starboard) values as positive. Positive minimum values and negative maximum values can be entered in the input boxes for breadth if the width grid runs towards the port side, but when the settings are opened again, the minimum values are shown as negative, and maximum values as positive.
-
Group overview – Displays the values of all blocks in the block group in a separate window.
Change the settings as desired. Once you have made the changes, click Modify. Note that the number of the block cannot be changed.
To add block numbers, enter the block number in Block name and click Add. The number must be positive and must not be in use already.
Important: To save the changes, click OK. If you close the dialog without clicking OK, the changes will not be saved.
To delete all existing values, click Delete.
The block area is used in the presentation of a block in the 2D- and 3D-Contek applications. The system compares it with the construction area within a drawing to check that no construction items are fully or partly outside the block area. If a construction item is found to be outside the block area, you can manually adjust the block area values.
The block area is defined for each drawing in its plane. In depth the construction area is defined by the biggest visibility setting value. When the system searches for adjacent blocks, only blocks visible within the block area are taken into account. It is important to set the values for block area and visibility correctly. Otherwise there may be a decrease in performance if too many blocks are searched.
If the block area is completely outside the ship, it will not be presented in the 3D-Contek application.
Note: The comparison between the block area and construction area is not done when the block has been opened in browser mode.
In COS (distributed) projects, the changes are applied at other sites only when the block is saved and downloaded after replication.
