Hi Andreas,

it can be found in expression builder, Group „Geometry”, function name “project”. Syntax: project(point, distance, bearing).

Hi Benjamin,

What ist the exact name of the expression? Are you sure it is a Python expression? If it is a built-in expression it is most likely implemented in C++.

Hi,

I'm looking for the python code of the geometry function „project" that shifts points by azimuth and distance. I couldn't find this in .qgis2/python/plugins/refFunctions (Windows). Any idea where I can find it?

Thanks!

Regards
Benjamin

Hi Benjamin,

Of course they can be found in the Python folder ;-)

Go to .qgis2 (in Windows in the user profile folder, in Linux/OSX in the home folder), then to "python/plugins/qgsexpressionsplus" or "python/plugins/refFunctions".

Self-written custom Python functions end up in "python/expressions" and your chosen filename when you created the expressions.

Hi all,

I'm looking for the folder where the python files of functions available in expression builder are installed. I want to get some inspiration for a special custom function I have to write. Thanks for any help!

Best regards
Benjamin
