Yeah actually it does. Thanks. There are a few dimensions My drawing doesn't have plus the roof cutaway helps.
Just for that, I'll show you this.
I did this a few years ago just to see if I could make the roof. From there it just sort of expanded to the windows. Still have no idea how to do the weird angle of the front windows, but the good thing is I only need to draw 1/4 of the car and mirror it a couple times.
As the technology gets better, I have a bunch of interurbans and trolleys I want to draw up. For now I'll probably do some 'simplified' drawings. Enough detail to look good but not so much that you focus on how poorly rendered the detail is.
