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

1. Registered forum members do not see this ad.

I'm probably not the person you want reviewing your drawings as I tend to be too much of a perfectionist. Maybe another forum member will volunteer to look them over.

2. Ok.
But sometime it is better to receive the feedback from a perfecionist person.
So I can try to do it better.

3. If someone else can help me on that, I will appreciate it.

4. Hello, I am doing the Civil Drafting Plate 3 right now and i have been reading through threads and looking at the screenshots of examples all day today but still am not able to understand how to start this plate I am running out of time and really need to finish this!!! It says the horizontal scale is 1"=60' does that mean when making the grid/chart the station points are gonna be 60' apart instead of 50' ? how do I set it up???? Please help! THe pictures alone were not enough for me to understand!

5. The instructions for setting up the grid are contained within the project PDF.

You should also go back through this thread and look at the following posts...#32, 35-37, 39 and 49.

6. I did actually, multiple times. And it all makes sense to me except how to set up the grid and how to get the points from the curved part of the driveway because I can't do a straight line down at that specific part. In the project booklet it has not a lot of directions and nothing is really explained about the grid. I'm just wondering how I know the dimensions for the grid part..... Between the station points and the contour levels....

7. Set out the stationing along the bottom of the grid. If one inch equals sixty feet how many inches would equal 50 feet? How many inches would equal 100 feet? Stationing is usally laid out in 50 foot increments starting with 0+00 then 0+50, 1+00, 1+50, 2+00, etc. Stationing runs horizontally from left to right.

Your contour level is in 10 foot increments. These run vertically. One inch will equal 10 feet vertically; two inches vertically would be equivalent to 20 feet. Pick a range of contours that mimics what you see in your plan view (hint: look at the contours your road centerline crosses).

8. 40k is approaching. Any day now.

9. Thank you kindly for your response, I really appreciate it. When I plot the points from the curved part of the driveway how do I get the right position of the point? I know I have to do a curve from where the centerline crosses the contour line and then draw a straight line down from the curve to plot the curved area of the driveway. How do I know how long the curve is and what kind of angle it will be? The unit booklet never explained this and the project booklet does not say a word about this either. So how am I supposed to know????

For what you are doing measure from the nearest stationing point, like 1+50, to the point where the contour crosses the centerline of the road. So if your 190 contour falls 38.5 feet beyond station 1+50 plot the point at station 1+88.5 in your profile.
