Hi there. I just found your blog and I like it a lot. You have some blueprints and diagrams I've never seen before. Very cool. I have a collection of blueprints you might like to check out. It's all disney stuff I've drawn myself so it's not as professional as yours but it's pretty complete.http://www.flickr.com/photos/63631877@N00/sets/
Very cool drawings! I shared the link in a new post. What software do you use?
I use Vectorworks (it's a professional CAD program). It's good for simple buildings with walls doors and windows but I keep meaning to learn something else for recreating the fancier stuff. Rollercoasters and rockwork aren't easily done unless you have a fancier 3D program
I'd love to hear from you!
