What does ¾" = 1’-0" scale exactly mean? How will I draw it? Can someone adequately explain it to me specifically step by step if you would please.
3/4 of an inch on paper will equal 1 foot on your layout when you draw your track plan on your benchwork. For example say you have a sideing that is 1.5 inches long on paper, when you lay your track it would be 2 feet long.
How do you count 3/4 on a ruler again?
There is a triangle shaped ruler that’s called a drafting or architectural scale ruler. It has different edges marked off in the different standard drafting scales. And yes, I’m old enough to remember these from learning to use them in school. To us, a CAD was a guy that treated women poorly.
They look like this:

3/4 inch equals one foot is exactly what it says. 3/4 of an inch on the drawing is equal to one foot on the finished item. The scale mentioned above will allow you to read the dimensions directly off there and translate them to the real size with a regular ruler or tape. It also works the other way if you’re doing the drawing.
A more detailed background and explaination:

I’ve done layout diagrams and room drawings for years this way.
Al I needed to know is if 3/4th is the 3rd line in the inches, mm, or cm on a ruler.
Do you see the 1/2 inch mark? The 3/4 mark is the NEXT longest line before the 1 inch mark.
I have no interest in being offensive (and I am going to break my own rule that says if you say that, stop and throw it away), but I hope that wasn’t serious. Your profile says you are a college student that plays video games, if the ruler question is serious you need to be doing more student and less games! On the other hand, model railroading is a hobby that can force you to learn a lot of things, math, architechture, physics, history, geometry, etc. So maybe you need to spend more time model railroading!
The advice on using an architect’s scale is right on, it takes all the guesswork out, and you don’t have to keep multiplying and dividing by 3/4, and keeping track of the inches and feet in real life as opposed to scale size. For sketching I like to use graph paper, and choose a number of squares per foot that lets the layout cover most of the sheet.
A much better answer than mine, I just get frustrated by the state of education sometimes!
I’m feeling bad now, I will crawl back under my rock!
Don’t feel bad Jeff, I was almost AFRAID to answer it myself, lol.
Yes
That was not offensive in any way. That was a smart logical good statement. It’s true.
**No.1—**Find a ruler (scale) find one inch, (there are 12 on the ruler-on some) the inch can be broken down into 3/4 of an inch, 1/2 of an inch, 1/4 of an inch— Oh forget it, I can’t possibly go on ! The U.S. is the only country in the world still using the “English” antique, complicated, insane method of measurement, use metric ! I won’t ask you to figure out what 17/32" is.
1/32" more than 1/2" [;)]
i didn’t know rulers went that detailed (other than specialty rulers, like for drafting/scale model work). most of them are 1/8th or 1/16th as the smallest increments
But lots of plans are published at 3/4" per foot, which doesn’t translate to metric well at all. And of course here all the materials we buy are foot and inch based. Other than that, yep, metric would be way easier!
By the way, 3/4" to the foot is 1/16th scale, real life if sixteen times bigger than the drawing, if that helps!
1/16th, thats S scale.So it’s 3/4" to the foot… learn something new every day.
NOOOOOOOOOO!!! S scale is 1/64th scale: 1 real foot = 64 feet. 1/64 of an inch = 1 inch. 3/4 inch = 48 scale inch or 4 feet. I have to admit that anybody asking these questions needs to do a LOT of studying on what scale means and ratios. Having an engineering degree, this exchange is damn scary. Dave H.
bah scrambled brains from CS homework (WHY am I a CS major!?).
OK everyone, just disregard my previous post… better yet, I should get rid of it…
1/16th scale would be pretty big, a 40 foot box car at 2 1/2 feet.
Also an engineer (electrical), I agree about the scariness. The hopeful part (maybe rose colored glasses?) is that model railroading is a pretty sneaky way of forcing one to learn some of this stuff.
yeah, I wasn’t thinking right when i posted that.
no more homework for me till my brain gets better…
No…do your homework while your brain is crossed up, post to boards when you are thinking clearly…no, wait, that’s probably bad advice…[oops]
