What is this plastic measuring thing?

    I was watching a tv show (the astute watcher will recognize it as How I Met Your Mother), when I saw one of the characters holding this thing (the curved plastic measuring-thing).

    My dad used to have one of those on his work bench, and I used to play with it as a kid, but seeing it in the TV show I realized I had no idea whatsoever what it was. I tried googling it, but I ran into the inherent problem of figuring out what I would call it and I couldn't find anything, so I was hoping PF would help me.

    The character in the show is an architect and my dad is an engineer, if that helps.

    Thanks :)

    No the other thing, the one that looks like a big plastic nine (I'm so technical).

    Huh. Didn't even notice that. No idea. Looks like a specialty protractor, but I'm reaching here.

    Here's one I found (maybe?) googling drafting tools. No name, but very similar looking (scroll down a bit, it's yellow).

    Sorry. :tongue:

    My monitor is too old. I couldn't even see the french curve in the OP's image.

    French curves were very valuable tools in the days before CAD. I probably have more than a dozen of them in storage somewhere. Haven't uses them since about 1980.

    It's definitely a French curve, as others have suggested. Like Pkruse I have several of them.
