Mapping of BPMN to Petri net

Hello everyone,
How can i convert the BPMNto Petri net,
well i’m using the first version of signavio which is almost a blank version
which src in the code we should change ?
Thanks in advance.
Kind regards

Can you please provide more context. I don’t understand your question.

i’ve deploy the first version of signavio on the tomcat and i wanna create module called export XML in order to read the file.xml by another application aiming to display the colored petri net with the extention added in the original code.
so my question is which pachake i’ll modified it to get a result
and which is the best way to do it ??

How is Signavio related to our toolkits?
