Hi,everyone,What is the best order to read the code？

I read it for a week but  I cannot understand anything.

This is hard to say @chippy.

Which C++ skills do you have?
What do you want to understand?
Any special interests?

Hi, What I did time ago(not in LibreCAD) was to find areas of interest, in my case bugs or things that I wanted improved in the target program(Tux Paint), then try to address them.
At first my attempts ended always in breaks/crashes ;) but slowly I started to learn and being useful for the program(and me)

I am sure there are other ways, but this one worked for me :)

I want to write a DWG file reader with libredwg that support more dwg edition.
I read librecad source code to  know how  the parsed data by libdxfrw becomes a graph,so that I can do the same thing with
libredwg.
I am a C++  novice and I can understand some Qt official example.
I have not used the boost lib.


Librecad is too huge to me.I want to know a best order to read source.
