True, because the lack of tutorials regarding how to use Inkscape for svg creation and making those work perfectly on Fritzing which is what we are discussing right now.
I haven’t seen any part made by you since I just go ahead and try to make my own parts design while sticking as much as I can to the real looking in order to obtain a high quality part and accomplish user needs.
I haven’t done anything like IC since I want to produce the same looking PCB of real parts. As you can see, the three current parts done by myself have been 2 little modules and one big board (LinkIt One).
I feel like pin label assignment is way better achieve through svg id renaming instead of doing it on Fritzing editor. The first way does let me edit the piece, move things around and such stuff, then just load it on editor and it automatically assign them for you.
It is my personal thought since I had problems while trying to import the pieces due to generated temp files every time I load a new breadboard svg file that gets stored on fritzing folder.
I hadn’t idea of these tutorial 
I have the same opinion about Fritzing strongest feature so far.
I don’t want to sound rude but it seems that we don’t have a common agreement on how to make the process of the parties friendlier and the best possible for this.
As I can see, the learning curve has been different for many of us, but seems to be some who are in favor of making the pieces work with the grid of the program, others looking for a piece as accurate as possible (in measures) to the real one and finally, some that only want the piece to be functional no matter what else.
I really didn’t found an Eagle file for my current pieces and just downloaded eagle in order to check an Arduino Ethernet Shield 2 size (today), but I do rather prefer making the pieces good looking and sticking into Fritzing grid (doesn’t matter if pin / headers doesn’t match real positioning) if its cost me like 2 days or more (which is my current average).
Great! So you guys are gonna do some kind of “Part creation guidelines” along with this new API client?
