- [Voiceover] Using grips is probably the simplest and most direct way to edit parcel lines. In this video you'll learn about the two different types of parcel grips and how to use them. If we zoom into this area, we see a part that we may want to modify. Looking at this large parcel in the back, let's say we've got requirements that dictate that this lot has to be five acres or more. So we need to make some edits. And of course that's going to maybe affect some of the adjacent lots.
So how can we use grips to make the edits that we need to make? Before we get to that, let's talk about the two types of grips that you run into when editing parcels. The first one I'll show you is associated to a parcel line that's been created with one of the automated parcel creation tools like Slide Line Create or Free Form Create. Notice that this line only has one grip, and that it's diamond-shaped. Now, if I were to click another parcel line, say, this one, you notice that its grips are square, and there is one at either end.
And if this had multiple vertices, more than two, or three, or four, or ten, we would see a grip at each one. So, these grips, the different shape is a clue that they actually do behave differently. So, if I click on a square grip, I can pretty much move it anywhere I want to. It behaves like you would expect it to if you are familiar with any AutoCAD-based program or just AutoCAD itself. I can place this grip anywhere I want. The diamond-shaped grip, on the other hand, has a special behavior associated to it.
As I move this grip, it keeps the line at the same angle, typically perpendicular, with the line that it's connected to. You can see, as I swing this grip around, it's maintaining a perpendicular angle with the arc. And I also get this kind of ghost line, but if I pick a spot for this line, it will actually kind of heal itself at the back of a lot. So, no matter where I put it, it always finds the lot line directly across from it, extends that line, and kind of heals up the parcel.
Something else that's interesting to note is, as I make these changes, the lots are smart. So look at the acreages, or the area measurements, in the labels. They actually change as I make changes to the lot line. And not only that, the labels recenter themselves in the center of the lot. So this is one of those time-saving features that comes along with the dynamic nature of Civil 3D. The fact that I can make changes like this, you don't have to go on and manually edit labels, or move them around, or get values to be where they're supposed to be.
So let's get back to our task. We want to change this to a five-acre lot or more. So we can take advantage of these grips and say, "You know, what if we just took this lot out "and made it part of this lot?" Well, that's an easy grip edit. We can click the square grip, and I'll use one of my object snaps, I'll Shift, right-click, and select Endpoint, and now just simply snap it to the end of this lot line. So now I've got a lot that's 5.25 acres. I haven't affected this lot, so I know that its frontage is good, and any of the other requirements that went into making this lot have been met, because I haven't changed this lot.
Of course now that I look at it, I'm thinking, well, there is a big size difference between these two lots, so I wonder if I can even this out a little bit. And I can do that by simply clicking the lot line and sliding it, until I get a more even lot configuration. And I got really lucky there, they are both exactly one acre. Now, I'd want to check my frontage here, that may not be enough frontage, in fact I'm guessing it probably isn't. But that gives you an idea of how easy it is to grip-edit these lot lines.
So, as you can see, editing with grips is an easy and direct way to make changes. But what if you want to be more precise or work with exact dimensions? Keep watching, and you will see how that's done, too.
