Creates a new assembly consisting of the parts or other assemblies you select in the graphic view or the Workspace Explorer. You can also use the command to create a new assembly block consisting of the parts, assemblies, or blocks you select in the graphic view or the Workspace Explorer.
An assembly block is a collection of blocks, assemblies, structural parts, equipment, outfitting parts, and outfitting assemblies (such as pipe spools, HVAC, and so forth) and is a child of the top-level block or another assembly block.
Collection of assemblies, structural parts, equipment, outfitting parts, and outfitting assemblies (such as pipe spools, HVAC, and so forth). An assembly is a child of a block, assembly block, or another assembly.
You can think of an assembly as a folder containing other assemblies and parts. To create a new assembly, you must select an existing assembly or block to act as the parent. You can also select parts to assign to the assembly. After you create the new assembly, you can make any changes you require (such as properties, assembly content, or orientation) and save the new assembly to the hierarchy. After you create the assembly, you can change assembly content from the Workspace Explorer using drag-and-drop, or you can use the Cut and Paste commands. Cut and Paste are available both from the Edit menu and the shortcut menu of the Workspace Explorer.
Paste is available for block, assembly, and assembly block objects; Cut is only available for assembly objects.
Top-down versus Bottom-up Planning
The default process for creating blocks is based on the concept of top-down planning. By using the Nested option in Split Block , you create a hierarchy of blocks starting with the top-most block (B0), the entire marine structure, and successively breaking the blocks into smaller volumes that are children to the larger blocks.
Blocks can also be created using a bottom-up planning concept. In this case, all of the blocks are created using the Flat option in Split Block so that all of the blocks are at the same level. The block hierarchy is then created by creating assembly blocks using New (Block) Assembly . In other words, blocks are initially broken into their smallest components at the bottom of the hierarchy, and combined upwards to create the large blocks.
At some point for both top-down and bottom-up planning, block definition stops and assembly definition begins using New (Block) Assembly . The point where this transition occurs is a function of the workflow of the facility and is not determined by the functionality of the software.
