Join Dustin Manning for an in-depth discussion in this video Design a parcel layout, part of Cert Prep: AutoCAD Civil 3D Certified Professional.
- [Instructor] To design a parcel layout, we first have to get the limits of our parcels. In this case, what we're seeing is the center line of a road with a 50-foot right of way and a closed polyline that represents where our parcels are going to be placed. And remember that parcels exist only when there's subdivisions amongst parcel segments. So the first thing we need to do is turn this into a parcel, and we will convert that in the home tab, create design panel, parcel, create parcel from objects.
Here we can select the site that the parcel exists in, so, remembering parcel segments that are in this site, they are going to interact and make subdivisions. What style, once the parcel is created, is it going to have? So, the color or hatching that the parcel has. And then, how is it going to be labeled? And we can also add segment labels at the same time. So we're going to erase the existing entities, because we don't need a polyline and parcel segments, they are representing the same thing. Click OK, and we've created a single parcel, called property one.
Remember to select the parcel. You do not select the parcel segments. Instead, you select the label representing the parcel. Now, we can subdivide this parcel into multiple parts, based on certain criteria. We could manually draw lines in, offset them, and figure it out all ourselves, but thankfully, there's better tools for that. Under the parcel menu, we'll choose parcel creation tools, and the first thing we want to do is activate this chevron so that we see the settings.
Our minimum area is going to be 1,890 square feet, our minimum frontage is going to be 60. Now, it's important to note where this is going to be measured. So, by default, it's going to measure the minimum frontage at the offset. Our offset is set to 15 feet. So, 15 feet back from the right of way, it's going to measure a minimum of 60 feet. Now, using these parameters, we're going to create parcel lines that are perpendicular to the right of way by choosing slide line, create.
Again, we're going to see this same dialogue here, where we can choose the parcel style and the labels. We can take defaults here. Click OK. I'm going to move our dialogue out of the way. And the first question down here is, which parcel is going to be subdivided? So, I can choose the label, and we're going to tell it what is the start point of our frontage. So we're going to work from left to right, using the endpoint snap, going to click here, and you'll see, as it traces along, it gives us that orange glyph, and choose the end.
So now we have the beginning of our frontage, the end of our frontage. And at what angle do we want to draw these new parcel lines to that frontage? I'm going to choose 90, enter. So now, we haven't committed these changes yet, but you can see where the parcels are going to be placed. The first thing that you'll notice is, we have an oversized parcel down here. That happens because, on the automatic layout mode, it's placing all the extra square footage so, if anything was over 10,890 square feet, all that extra area is being placed in the remainder in the last parcel.
Alright, so, let's change that and let's just redistribute everything. We had the same number of parcels, but now, that extra area has been split between them all. Now, if this suits us, we can just accept the result and click yes, or we can do no and start over. Once I click yes, close my dialogue, you'll see now, we have all new properties. Now, I'm able to make manual adjustments as needed. If I select a parcel segment, you'll see now that, unlike if this was drawn with a polyline, I don't have a node at the beginning and the end of the line.
I'll zoom in so we can see it a little better. You'll see that this was created with the slide angle create, so it's going to maintain that 90-degree angle to the frontage, and if I want to adjust that parcel, I can click the slide and just move it. And now everything around it updates accordingly.
This course won't teach you everything about Civil 3D, but it will refresh your skills and prepare you for the exam topics and format. Once you're finished, you can feel confident taking the AutoCAD Civil 3D Certified Professional exam.
