# Thread: Penn Foster Civil Drafting project plate 3 and 4

Thanks, I will definitely change my trees!

Ok, I know what to do for my section then...but I am once again confused for my profile. What I was plotting was where the contours crossed the centerline.

2. Maybe our terminology needs to be adjusted. The term "centerline" would be used to describe a line that runs down the length of a road or, in this case, a very long driveway. A section line is one that is arbitrarily placed to indicate where a section through a road or a driveway might be useful. Take an Exacto knife and cut off one of your fingers about midway from the tip. Turn you hand towards you so you can see the end of your finger where the tip used to be. See the muscle and the end of the bone? That would be a section.

In a few minutes I have to take a ride somewhere. I'll be out of touch for a while. However, if you have any further questions go right ahead and post them. I'll see what I can do to answer them later today if possible.

3. I understand what a centerline and section is. Obviously I am not understanding what a profile is.

On my attached drawing, the left hand grid is for the centerline of the driveway. The left hand of the grid is the start (center of cul de sac) and going horizontally is stationing at every 50' (also indicated is the curb, pow, pc, pt and end of driveway) . Vertically is the elevation, starting at 110 going up to 190.

What I plotted on this grid is the culvert and the points where the elevation crosses the centerline in relationship to where it is lengthwise on the centerline. For example @ 180 elevation it crosses the centerline 75.94' away from the cul de sac and another 337.52 towards the end of the driveway.

4. So do you or anyone have an image of what plates 3 and 4 are to look like?

5. You can find images of plates 3 and 4 in one of the other civil threads if I am not mistaken.

6. I have seen lots on plates 1 and 2 but not for 3 and 4.

Can anyone tell me what the labels on section A an B say? They are too blurry for me to read and Im not sure how to label my graphs horizontally or vertically.
