| SMG
(.smg)
|
The default file type. A single file that includes all property, geometry, view, and
animation information.
|
| Package (.exe)
|
An auto-executable file containing the following:
-
.smg file
- Composer Player executable
Use packages to distribute models to users who might not have
Composer or Composer Player installed. Opening the package file
(.exe) runs Composer Player and loads the
Composer data. Note:
The Composer Player documentation is not bundled in the package. It is accessed online.
|
| Product (.smgXml)
|
A multi-file format consisting of all the
.smg components:
The
.smgGeom,
.smgView, and
.smgSce files must have the same name as
the
.smgXml file.
|
| Project (.smgProj)
|
A multi-file format consisting of one or more Composer
product files and a project (.smgProj) file. The
.smgProj file is an XML file that
references the top-level
.smgXml,
.smgView, and
.smgSce files that comprise the project.
- The
.smgXml,
.smgView, and
.smgSce files can be any name and
reside in any folder.
- The
.smgXml and
.smgGeom files must be the same name
and reside in the same folder.
Projects organize your Composer files into folders and let
you share references. For example, two projects can share the same
.smgXml,
.smgGeom, and
.smgView files but have different
.smgSce files. Projects also let you
import multiple subassemblies even when you do not have the main assembly file.

| Fully Shattered
|
A Composer product with multiple .smgXml and
.smgGeom files. Note:
All
other Composer formats contain geometry and structure
information in one (.smg,
.exe) or two
(.smgXml,
.smgGeom) files and are called monolithic
file types. In the fully-shattered format:
- The main assembly and each subassembly has a
.smgXml file that includes the
neutral properties, assembly hierarchy, and position of
its parts. It also includes references to all the parts.
- Each part has a .smgXml and
.smgGeom file.
Fully-shattered assemblies have several advantages:
- The assembly loads all its parts by reference. An
assembly does not have geometry files. This keeps the
file size of the main assembly small and lets you reuse
parts in multiple assemblies.
- You can load assembly parts as you need them instead of
loading the entire assembly when you open it. For
details, see the options in the Open dialog box and the
Load on Visibility command.
To load a part, right-click the part in the Assembly
tree and click .
- You can load parts with different levels of details. If
you create your fully shattered assembly with more than
one level of detail, you can choose the level of detail
on the Open dialog box.
- You can perform incremental updates. Because parts are
loaded by reference, you can update only parts that have
changed.
When using fully shattered assemblies, you must be aware of
the following points:
- You cannot create fully-shattered files from Composer.
Use Sync.
- Create projects with , not Save As
 . Because Composer measurement
actors, animation keys, and other authoring content is
stored in the top-level project assembly, that content
is lost if you create the project using Save
As
and then retranslate the
top-level CAD assembly in Sync.
- Fully shattered assemblies reference the last saved
configuration of its parts. If your assembly uses
multiple configurations of a part, then it displays the
last saved configuration for all instances of the part.
Therefore, you will get improper results when converting
(from Sync) in fully shattered mode an assembly that
contains multiple instances of the same part with
different configurations.
- You cannot change the neutral properties of a part in a
fully shattered assembly because the part is loaded by
reference into the assembly. To change the neutral
properties of a part, open the part in its own window.
- When you modify a subassembly such as adding/removing an
assembly group or merging/exploding actors, you break
the fully shattered structure. All the associated
structure branches will be saved in the top assembly
file.
- Undoing an operation that breaks a fully shattered
structure does not restore the fully shattered
structure.
