Explore the intricate process of parcel interactions between sites with this thorough guide. Learn how to create additional parcels, move objects from one site to another, and understand how different parcels interact with each other.
Key Insights
- The article explains how to create additional parcels on the right-hand side of the drawing and then delete them. This involves creating three rectangles, two small overlapping ones and a big one, and assigning them to different sites.
- You can move objects from one site to another in Civil 3D. The article demonstrates how to migrate a property from site two to site one. This migration creates an additional property in the middle, with the interactions creating different properties or parcels.
- Interactions differ depending on whether they are on the same sites. For example, moving a boundary line to bisect a smaller rectangle on the same site creates an additional parcel. However, migrating sites can lead to numerous interactions, making it hard to track which properties are on which site.

In this video, we're going to talk about parcel interactions between sites. So what we're going to actually do is we're going to be working off to the side of our drawing, not with our main drawing.
We're going to be off in the right-hand side over here, and I'm going to create some additional parcels. And then when we're done, we're going to go ahead and delete them. If you want to follow along and actually create, you can go ahead and do so.
But if you don't feel like doing that, you can also just sit and listen. And then I will end walking us through this creation method and talking about site interactions, and then we'll end up deleting everything that we create in this video. So I'm going to go ahead and pan over to the right, and I'm going to create three rectangles.
So I'm going to create a large rectangle and two smaller rectangles that overlap. And what I'm also going to do is I'm going to go to sites over my tool space. I'm going to click on sites, I'm going to right-click, and I'm going to select new.
So I'm going to select sites and I'm going to call them site one, very creative, and site two. And so I'm going to go ahead and click okay. And what we have here is now we have site one and site two.

We have our development site and our survey site. So I'm going to go ahead and drop down into parcels, do parcels from objects, and I'm going to select my outer rectangle and I'm going to click enter. And then I am going to specify that it is going to go to site one.
I am going to leave the parcel styles, layers, and area labels the same. And I'm going to choose to erase existing entities and click okay. From here, I'm going to then drop back in, create parcels from objects, select my upper left rectangle.
I'm going to click enter. I am going to put it onto site two and I am going to select okay. Then I am going to go to parcels, parcel create from objects, select the other rectangle that I've created, and I'm going to hit ENTER and I'm going to select site one.
I'm going to click okay. And so what you'll notice now is I have three properties. I have property two, property one, and property one.
Now this doesn't seem like it should make any sense. I have one property here and I have one property here. How can they both be called property one? That's because the upper property one is on site two and the lower property one is on site one.
Now if I go and I select property two, what you'll notice is it highlights the outer boundary and it highlights the boundary for property one. And that's because my outer rectangle for the first parcel that I created and the inner rectangle for the third parcel that I created are interacting with each other to create a parcel that is the outer area less the inner area. So I have property two, which is this outer area.
And then I have property one, which is this inner area. Now property one here doesn't interact with either of these because if property one was part of this site, what you actually
Would see happen is that the lines from property one would interact with the lines from the properties that are in site one. And so you would have an additional parcel creation.
So I'm going to show you that interaction by selecting this upper property one and I'm going to do a migration. So what I'm going to do is I'm going to right click and I'm going to select move to site. What you can do in Civil 3D is you can take objects that are in one site and move them to another site.
So I'm going to select move to site and what Civil 3D is going to ask me to do is it's going to ask me to specify my destination site. So I have the option to move it to any site other than the current site it's located in because it doesn't make sense to move something from, well you can't move something from one site that it's currently in and keep it in the same site by doing a move it just doesn't make sense. We're going to take our parcel that was in site two and we're going to migrate it to site one using this move command from move to site.
So I'm going to go ahead and click okay and what you'll notice now is that we have created an additional property in the middle here. Now in doing that we have parcels or properties. We have property three which is the outer rectangle less the interactions between property one and property three.
Now we have property four which is the basically the overlap of these two rectangles here. Then we have property one which is the remainder of this small rectangle you know less the area that's interacting with this other rectangle over here. And then we have property two which is the large outer and then the removal of the areas that are in the center.
So that's interesting in that they are interacting with each other. The other interesting thing is that I can take this boundary and let's say I move it and I move it so that it's no longer wrapped around the outside of the other two properties. It only interacts over here.
What I've done now effectively is I've moved that boundary line so that it bisects this smaller rectangle and I've created an additional parcel. So this is how interactions work when they're on the same sites is that they have now you've now effectively created an additional parcel by moving that boundary element into an intersecting position across the smaller rectangle. If I go ahead and I move it back that property goes away.
Now if I was to take this property here and I was to move it to site two and I said okay. What I now have is I still have this property because what now I've done is I've essentially moved this box and this inner boundary to a different site. So it's not like I have now taken this outer boundary and moved just the outer boundary.
I've moved the boundary definitions for that property to site two. Now this property has two boundary definitions. So what I can do now is I can move this and what you'll notice happening here is I will move it across here and you're now going to see many different interactions happening and that's the problem with migrating sites is that now we've got all of these different properties interacting with each other and you're not quite sure which ones are on which site and what's going on.
So generally it's a good idea to start your properties on an appropriate site and then when you have these large scale interactions what you what you're going to want to do is like in
The event of our interactions here is you can move the larger outer boundary away completely and then migrate it so you don't have those inner interactions happening when you do that move command. So move the large outer boundary away make that movement make that change to a new site move it back into place. If you get some strange things you can always undo in the drawing but just know that site-to-site interaction is it's a benefit for a lot of civil 3D use but there are some drawbacks when you start dealing with moving sites inside of other sites and doing those kind of modifications.
So I'm going to go ahead and delete these and then I'll meet you in the next video and we're going to start talking about labeling things.
