Join Dustin Manning for an in-depth discussion in this video Drawing a boundary, part of AutoCAD Civil 3D: Topographic and Boundary Survey.
- [Man] Let's look at two ways to recreate a boundary. Let's say we're doing deed research, and we don't have any digital records of anything, so we're going to use the Bearings and Distances to recreate this boundary. We'll go to the home tab, to the draw panel, and under line, we'll choose Create Line by Bearing. Now, if we have the coordinate as a point of beginning, we could first start there, but in this case, we're just going to start at a random point here in model space. I'll click here. Immediately, we start getting some useful feedback for choosing the quadrant and the direction that we're going to draw in.
So, I'm going to start in this corner here, so we'll enter in this Bearing information first. And that's in the northwest quadrant, so we'll go to quadrant four and click, and you'll see that it's highlighted by the red lines. For the Bearing, we'll enter in zero, and the way that we input this is separating our degrees, minutes, and seconds with periods. We'll do zero, two, nine. And now, you can see that we're locked in to that Bearing, and we'll put in a distance of 390 point two.
Continue on to the next one. Now pay careful attention to the direction and the Bearing. At times, you will see them that they're flipped. So in this case, we're not going northwest, we're going southeast, so we will choose quadrant two, we'll input again, 78 point O nine point three. Distance of 532 point one. Continuing on. Now we're going southwest to quadrant three.
(clicks) Add in our distance. (clicks) Next, southeast. (clicks) Distance of 235 point four. Now we can choose to close those. First, we do need to Escape out of this Bearing and Distance command, and now we can use the Close command. Enter one.
Next, let's say we've actually surveyed these points. I'm going to remove these lines from our example. Let's say we've actually surveyed those points, and we picked up iron pins, or other markers in the field. And we just want to draw and close this boundary out based on the points. Again, I'm going to choose the Line command, and this time, we're going to do Line by point Range. So when I click that, all I need to do is find my beginning number here, so we'll start at eight, and I'll put in eight on the command line, and then a dash, come back around to twelve, and then, to close it all out, I'll add a comma, and go back to point eight.
And there we are. That's the quickest way to draw that if we have a known point range. So there are two ways to recreate a boundary, and draw it in Civil 3D. Now let's take a look at labeling our boundary.
