Hey everyone. Just joined up today because I can’t find the answer to a ridiculously simple question. Plus I wanted to hang out with the cool kids! :devious:

I’m creating a poster with a timeline that needs to have a key: 1 cm = 1 million years. I need a horizontal line that equals 1 cm long, and then to end caps that are short vertical lines (|—| but where the lines are touching).

I’ve been using Photoshop since it was invented … literally … but on CS4 I can’t for the life of me figure out how to do this.

OR … I have that symbol on a previous version of the poster but it’s shorter than 1 cm and I need to make it longer. In previous versions I could draw a rect marquee around it, then free transform, hold down the command key and stretch it. CS4 won’t let me do that, and besides, it won’t measure 1 cm for me.

Please help an old lady out without laughing too hard …

Thanks!:sigh:
