Oops, I forgot a few other odd things. I *think* your expression allows these, but I'm not sure: .1 -.1 0. -0. 001 1E BTW, the color-code can be in scientific notation. The line-type can't, at least, it can't in LDLite. I'm betting LDraw would (...) (25 years ago, 23-Jun-99, to lugnet.off-topic.geek)

Hey now, that's beginning to look like the yacc grammer for LDRAW in the LDLite source code. If you want to get precise in the language spec, grab the LDLite lex and yacc files and either take them as the defacto standard or modify them to handle (...)
