General presentation of the GEOM python package
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
|
|
The GEOM python package essentially contains:
|
|
|
|
* Utility functions to handle GEOM items in Salome study (see ``geomtools.py``).
|
|
|
|
- add a shape to a study, remove from the study
|
|
- display a shape in a viewer, erase the shape from the viewers
|
|
- completly delete a shape (undisplay, unpublish, and destroy the shape)
|
|
- helper functions to manage the selection in the object browser
|
|
* Wrapping functions to help the usage of GEOM tools:
|
|
|
|
- a sketcher module to create sketches from the python API (see
|
|
``sketcher.py``)
|
|
* The visualization of structural elements: a function to create
|
|
geometrical 3D representations of mechanical models called
|
|
"structural elements" (see package ``structelem``)
|
|
|
|
The functions are distributed in the python package
|
|
``salome.geom``. The specification of the programming interface of
|
|
this package is detailled in the part :doc:`Documentation of the
|
|
programming interface (API)</docapi>` of this documentation.
|
|
|
|
.. note::
|
|
The main package ``salome`` contains other sub-packages that are
|
|
distributed with the other SALOME modules. For example, the KERNEL
|
|
module provides the python package ``salome.kernel`` and SMESH the
|
|
package ``salome.smesh``.
|
|
|
|
Visualization of structural elements (package ``structelem``)
|
|
-------------------------------------------------------------
|
|
|
|
The usage of the visualization of structural elements can be
|
|
appreciated with this set of instructions:
|
|
|
|
.. code-block:: python
|
|
|
|
from salome.geom.structelem import TEST_StructuralElement
|
|
TEST_StructuralElement()
|
|
|
|
This creates the geometrical objects displayed in the study below:
|
|
|
|
.. image:: /images/salome-geom-structuralelements.png
|
|
:align: center
|
|
|
|
Manipulate GEOM object in the study (module ``geomtools``)
|
|
----------------------------------------------------------
|
|
|
|
The usage of the ``geomtools`` module can be appreciated with this set
|
|
of instructions:
|
|
|
|
.. code-block:: python
|
|
|
|
from salome.geom.geomtools import TEST_createAndDeleteShape
|
|
TEST_createAndDeleteShape()
|
|
|
|
This test executes the following procedure:
|
|
|
|
* Create, publish, and display a cylinder
|
|
* Create, publish, and display a sphere
|
|
* Create a box, publish it in a folder "boxset", and display it with a
|
|
"pink" color.
|
|
* Erase the sphere from the viewer (the sphere still exists in the study)
|
|
* Delete the cylinder (the cylinder is no longer displayed and does
|
|
not exist any more, neither in the study nor the GEOM componet.
|
|
|
|
At the end of the execution of this test, you should have in the
|
|
SALOME session:
|
|
|
|
* the box, in a dedicated folder of the study, and displayed in the
|
|
viewer
|
|
* the sphere, in the standard place of the study, and not displayed
|
