How I learned to stop worrying and love Ldraw. (Subtitle: questions for programmers)

[Ken Drew]

Oh, it's paid? Did I just forget that I purchased it, or was it free at some point?

I apologize in advance if I do end up stomping on your work. But this idea has been in my head for a year now and won't go away until it's built. And now that I have found some spare time...

It has been a paid app since the end of August.

No need to apologize. I understand how you can have a code worm in your head that must be purged.
