\page import_export_geom_obj_page Importing/exporting geometrical objects
In Geometry module you can import and export geometrical objects
-from/into BREP, IGES, STEP files. The mechanisms of import and export
-are implemented via plug-ins, which gives you the opportunity to
+from/into BREP, IGES, STEP, ACIS and STL files. The mechanisms of import and export
+are implemented via plug-ins, which gives the opportunity to
expand the range of available formats by adding more plug-ins (for
example, CATIA 5).
-<em>To import geometrical objects from a BREP, IGES, STEP file:</em>
+The \subpage xao_format_page "import and export of shapes in XAO format" is implemented differently.
+
+\note If a plugin supports import of materials associated with shapes, these
+shapes are grouped corresponding to the imported materials. For the moment STEP
+import is the only plugin that supports this feature.

+<em>To import geometrical objects from a BREP, IGES, STEP, ACIS or STL file:</em>
\par
From the \b File menu choose \b Import. In the opening dialog box \b Import
select the required format of the file for importation and search for
-a *.brep, *.iges or *.step file.
+a *.brep, *.iges, *.step, *.sat or *.stl file.

+\note If the selected file is in IGES or STEP format and the length
+is not expressed in meters, it will be asked whether to take or not these
+units into account (see the picture below). This feature can be
+helpful if some wrong units have been written to the IGES or STEP file by a
+3rd-party software.

+\note If the selected file is in ACIS format (the use of this format
+requires licensing) and the file contains names for some shapes, it
+will be suggested to create groups by types (solid, face, edge and
+vertex) for all named shapes:

+\note It is possible to re-open from the initial file a previously imported shape if
+the file has been changed on disk. For this, select
+<b>Reload From Disk</b> in the context menu of the imported
+shape. The reloaded shape will have the same representation parameters
+as before this operation.
