This task explains
creation of an assembly. |
|
A 3D assembly allows
you to group several parts and store the assembly in a catalog. A 3D
assembly differs from a
Product Structure assembly in that a 3D assembly is typed, whereas a
Product Structure assembly is not.
The assembly itself is typed in the Equipment Arrangement
workbench. However, you can include parts from any Equipment and Systems
3D workbench, such as Piping Design or HVAC Design, Structures
applications, and mechanical applications. |

1. |
To create an assembly, start by
placing the parts you will be using. In the
example below a pump, nozzles and pipe will make up the assembly. When
you are placing the parts, you should note that the catalog may display
parts that are already
part of an assembly. You cannot place these individually, because they
are part of an assembly. In the sample catalog
provided with this application they
are identified by the letters EQA, as seen in the image below. The letter 'S' after
EQA means it is part of a standard assembly. The letter 'U' means it is
unique. How they are identified depends on your own naming convention.
It is recommended that you place the main part - which is a pump in
the example below - at the origin, or 0/0/0 coordinates.

Continue to place all the parts you want in
the assembly. In the simple illustration below the user has added pipe and a
valve to the pump.

3. |
Once you have placed all the parts, you need
to type and save the assembly. You should type the assembly only after
you have placed all its components. To do this:
- Open the Equipment Arrangement workbench.
- Click the Create Part button to display the
Create Part dialog box.
- Click the Display Class Browser button, next to the
Component Type
field, and select Equipment Assembly in the Class Browser that displays.
Select Standard or Unique Assembly in the
Create Part dialog box. See
below.
- Select the Product in the specifications tree.
- Enter a name for the assembly in the File Name field.
- Click Apply or OK. NOTE: These buttons will be grayed out until you
select the Product.
|
|
- A Standard assembly is one in
which the instances will point to the assembly reference saved in the
catalog - all placed instances point to this reference.
- A Unique
assembly is one in which a unique reference will be created each time
you place an assembly.
You can change the type of an assembly. You should
not change the type of a placed assembly - only change the reference. |
|
4. |
You need to publish connectors on the
assembly. This allows the assembly to be connected to other parts when
it is placed. To do this:
- Click the Create Part button to display the
Create Part dialog box.
- Select the assembly in the specifications tree or viewer.
- Click the Define Connectors button. The
Manage Logical Publications
dialog box displays.
- Select the connectors you want to publish in your assembly. They
will be added to the Manage Logical Publications dialog box. Click
Close
to exit. NOTE: When you delete an assembly the publications are not
deleted. You need to use the Manage Logical Publications
dialog box to delete them.

5. |
Add the assembly to the catalog using
procedures described in the Creating a Catalog
task. You should note that the assembly will be added to the catalog in
one of two ways.
- If you typed the assembly under the default type (or chapter)
'Equipment Assembly', then it will be added to the chapter to which the
equipment in the assembly belongs. If, for instance, the assembly
contains the equipment 'pump' then it will be added to the 'Pump'
chapter. (If the equipment type does not exist in the catalog, then one
will be created.) The type Equipment Assembly will not display in the
catalog.
- If you created one or more sub-types (families) under the type
(chapter) Equipment Assembly then the assembly will be added to the
sub-type under which it was created. It will display in the catalog
under the Equipment Assembly chapter and the sub-type, or family, under
which it was created.

Modify the functional physical mapping table
if necessary.
If Option 1 in Step 5 applies to your assembly then you need to do
nothing. If Option 2 applies then you need
to map it. Mapping links a function to physical parts. To do
this, you need to map (in the functional physical mapping table) any 2D
symbol that represents an assembly to the type 'Equipment Assembly', or
to a sub-type. See the Feature Dictionary section for more information
about mapping. For assemblies, do not add a Client ID to
the function name or physical part name in the table. |
|
- You can add a "sub" assembly within an assembly. However, you
should never modify the sub-assembly in any way - such as adding or
deleting a component. If you need to modify anything within the
sub-assembly then you should
delete the sub-assembly, rebuild it, and add it again to the main
assembly. In other words, the first level under an assembly can
be modified, further levels should not be modified.
- You can create connectors on the members of
an assembly, not on the assembly itself.
- You can have one part number for the
assembly, but you will be able to use part numbers of its components in
a bill of materials.
- Schematic driven parts placement of assemblies is possible.
- You can use one of the reporting functions provided with this
application to run various reports on an assembly, such as determining
the members of an assembly in a
BOM.
