To obtain the BOM of the assembly document, you need to do the following steps:
1. Enter the BOM data in the fragment document (the command “BD: Set BOM Data”).
2. In the assembly document, define the way of including the fragment in the BOM, either in the
fragment parameters or in the command “BI: Include in Bill of Materials” (“Tools|Bill of
Materials|Elements”).
3. Using the command “BC: Create Bill of Materials”, generate the assembly BOM.
Modifications of the assembly drawing are automatically reflected in the BOM. If necessary, an arbitrary
number of BOMs can be attributed to an assembly drawing.
Detailing Drawings Based on Fragments
When building an assembly, the fragment drawings may be modified according to the assembly parameters
via modifications of the fragment external parameters or the whole drawing when using associative
attachments. In this case, the fragment drawing files are not changed. However, if necessary, one can
automatically create separate documents with the drawings of the fragment parts adjusted to the assembly
parameters. We will refer to such drawings as detail drawings. One can create detail drawings for the whole
set of parts making up the assembly drawing. Once created, a detail drawing does not maintain any relation
with the source assembly drawing.
To get a detail drawing, use the option in the commands “FR: Create Fragment” and “EFR: Edit
Fragment” or the command “Open Part” in the fragment context menu.
Upon calling the command, a new document window will be opened, with a copy of
the fragment drawing loaded in it, with the external parameter values and
associative relations inherited from the assembly. The new drawing will be named
“Part” with a subsequent number, for example, “Part 1”. This drawing will be
treated by the system is a new document, with the system asking to define the name
to save the drawing as upon an attempt to close the window.
Usually, detail drawings are used for printing out hard copies of the detail drawings that can be different
from the original fragment drawing due to, for instance, modifications of the assembly variables. In such
case, you don't even have to save a copy of the detail drawing into a file. This is convenient in the case when
a parametric fragment used in the assembly has a corresponding fully furnished drawing. In such a case,
upon creating the detail, the user instantly gets a complete set of new documentation for the desired part.
Exploding Fragments
An inserted fragment can be exploded. By this operation, the fragment is removed, while instead the copies
of all fragment elements are created in the assembly drawing that were deemed visible at the time of
assembling.
The system can explode selected fragments in two ways,
creating drawing elements with or without construction entities.
In the first case, all parametric relations are preserved between
the former fragment elements by carrying over all necessary
construction lines for maintaining parametric relations of the
former fragment drawing. In the second case, the fragment is
transformed to a set of graphic lines attached to free nodes.
