Were can i find a section in photoshop to draw images in scale form i wanna be able to make the same length lines and stuff like that mayb a pixel counter were is it located in ps?

To do that, I usually either zoom all the way in to 1600% or use the info box.

If you don't see that box (it should have two tabs - navigator and info; click the info tab) go to Window>Info or hit F8. You may need to right click on the little crosshairs icon (the one in the bottom right) and select pixels, because I think it defaults to inches.
