Autocad civil sites drawing curve data

Should I trust the bearing and distance given rather than the scaled ruler? It looks like I have a new station to start a new street curve on the curve I just finished drawing. And it shouldn't If you scale from the PI to the PT, it should be this distance. All that means, is the intersection Back to my crash course This is the curve length and the intersection of Street 1 and Street You can post now and register later.

How to draw using Curves data and Line data? Back to Topic Listing Previous Next. Filter by Lables. Message 1 of 4. Can someone please let me know how to do it? Thank you,. Preview file. We will assume that this curve is tangent to the previous segment we'll cover non-tangent curves later. Draw a line perpendicular to the previous segment towards the inside of the curve. Make this line the same length as the radius of the curve.

You can use the. The opposite endpoint is the center point for the next curve. The image below is how it should look now the green line is the new one. Now rotate this line, using the opposite endpoint as the radius point.

Since this curve is to the right, rotate the line clockwise meaning you will have to enter a negative angle the amount of the delta of the curve.

Next pick the other endpoint of the line, that is the startpoint of the ARC. Next pick the endpoint of the previous line segment. Your curve is complete. Now we have another curve to draw. This curve is also tangent, but in this case the previous entity is a curve. If the second curve goes in the same direction, it's called a compound curve, if the second curve goes in the opposite direction, it's called a reverse curve. Notice that this curve is to the left, not the right, so this is a reverse curve.

We need to do the same as above to find the center point, except rather than draw a perpendicular line, we need to draw a radial line from the previous curve. In this case we already have the green line in place, so extend it out past the last curve a bit.

Now trim off the part that is inside the previous curve. It should look like this now. Now use the. The other end is the center point for the next curve. Now rotate this line the amount of the delta, just like before. Because this curve is to the left, the rotation angle will be positive, not negative. Now it should look like the picture below the radius point is not shown since it is so far away.
