Hi everyone,
I'm terribly sorry for the long absence. I recently stumbled upon this thread again and I see that a lot of you guys are interested by my work.
To do a long story short I kinda assumed the forum was dead and I also lost interest in the project.
But as you might have guessed I'm writing here because I've recently started working on the project again.
Currently, I'm still far away from having a functional tool to edit and create custom bricks.
Recently I've been more focused on a tool that creates custom palettes (aka lego set) for LDD.
If you didn't know, LDD has an undocumented feature to have a defined inventory of bricks with quantities (instead of an infinite number of all possible bricks) and tracks the quantity remaining of each bricks, which basically sums up to virtually building a lego set.
This tool is mostly done and only requires a little more error checking and a nicer user interface.
Once this is finished I will get back to develop an application for creating and editing custom bricks.
I'll keep you updated of my progress.
