Performance profiling
If the created PythonPart has poor performance, it's useful to perform performance profiling of the Python source code. This can be done using different tools described below. Performance profiling is supported by the PythonParts framework for functions and lines and it is done using the class ProfileUtil
With this tool it is possible to do performance profiling of the functions. Implementation in the code can look as follows:
ProfileUtil.profile(modify_element_property_local, page, name, value,
calls_to_print = 20, show_graphical_results = False)
The profiling results are shown in the Allplan trace window:

Visualizing the results
To make the results more visible, a graphical result of the profiling results can
be generated. To do that, set the parameter show_graphical_results to True
and use the following tools:
gprof2dot
grprof2dot is a Python module to convert the output from the used profiler into a dot graph. The installation is done with the help of the PythonPart InstallPythonPackage.
Manual installation
- visit https://pypi.org/project/gprof2dot/
- select Download files and download the package
- unpack the files and copy the folder gprof2dot to the Allplan folder ..\Prg\Python\lib\site-packages
Graphviz
Graphviz is an open source graph visualization software.
Here is an example of how the graphical result of profiling may look like:
Here is an example of how profiling can be included in the PythonPart script
in the function modify_element_property
PROFILE_FUNCTION = True
...
def modify_element_property(self, page, name, value):
...
if PROFILE_FUNCTION:
return ProfileUtil.profile(modify_element_property_local,
page, name, value, calls_to_print = 20,
show_graphical_results = True)
else:
return self.modify_element_property_local(page, name, value)
def modify_element_property_local(self, page, name, value):
Profiling an Interactor PythonPart
The PythonParts framework offers the possibility to profile the source code of an Interactor PythonPart which will be executed after a left mouse button click. To do this, the Python package keyboard must be installed (use the PythonPart InstallPythonPackage to do that). Profiling can be executed by pressing the ctrl key while clicking the left mouse button.
Manual Installation
Manual installation of the keyboard package can be done by following the steps:
- download the package from here
- unpack the files and copy the folder keyboard to the Allplan folder ...\Prg\Python\lib\site-packages
The installation is done with the help of the PythonPart InstallPythonPackage.
With this tool it is possible to do performance profiling of the functions. Implementation in the code can look as follows:
ProfileUtil.profile(modify_element_property_local, page, name, value,
profiler_type = ProfilerType.PY_INSTRUMENT)
Here is an example of how profiling can be included in the PythonPart script
in the function modify_element_property:
PROFILE_FUNCTION = True
...
def modify_element_property(self, page, name, value):
...
if PROFILE_FUNCTION:
return ProfileUtil.profile(modify_element_property_local, page, name, value,
profiler_type = ProfilerType.PY_INSTRUMENT))
else:
return self.modify_element_property_local(page, name, value)
def modify_element_property_local(self, page, name, value):
...
The installation is done with the help of the PythonPart InstallPythonPackage.
With this tool it is possible to do performance profiling of the lines. Implementation in the code can look as follows:
ProfileUtil.profile(modify_element_property_local, page, name, value,
profiler_type = ProfilerType.LINE_PROFILE)
The profiling results are shown in the Allplan trace window:
