Discover how to manipulate parcels using deletion methods within Civil 3D, including delete sub-entity and unification processes. Learn how to effectively remove boundaries between parcels and understand the implications and results when deleting outer boundary edges.
Key Insights
- The delete sub-entity option in Civil 3D allows users to remove specific sub-entities, which can effectively unify two parcels by eliminating the boundary between them.
- If an outer boundary edge of a parcel is deleted and there is no adjacent parcel, the parcel will be completely removed. This is a useful method for deleting parcels within the system.
- Standard deletion methods such as selecting an area label and hitting delete will not work to remove parcels. Instead, the boundary information that defines the parcel must be removed to delete it from the drawing.

In this video we're going to talk about how to delete parcels and also how to unify parcels using a deletion method. So what we're going to go ahead and do is we're going to get back into the parcel creation tools and we are going to select that option and we're going to be working in the delete entity or delete sub-entity button.
So inside of delete sub-entity if you select it what Civil 3D is going to ask you to do is going to select which sub-entity you'd like to remove. So what you can do inside of Civil 3D is if you want to create a union that you can't break apart again is you can basically instead of doing unify and deleting the line you can just delete the sub-entity. If I went and deleted the sub-entity between parcels 35 and 34 what it does is it unifies them or it basically removes that boundary between those two parcels and now I have if I was to exit out you'll notice that I now have a parcel property 35 that is both of those parcels before.
So same thing goes if I go into here and I go to parcel creation tools and I delete sub-entity and I select this line here I've now unified these two. That line is now missing so it's basically the same as if I had done unify and then gone back and deleted the line. So from here I'm going to go ahead and hit ENTER so that I can delete sub-entity again.
I'm going to delete out that sub-entity and so I can keep going and keep unifying these all the way back to basically what our original parcel was. So that was kind of my main goal was to get us back to our original parcels but if you take that one step further and say I deleted out an entity that we needed to create this full parcel what you're going to notice happening when I go back into my parcel creation tools is if I select delete sub-entity and I select a outer boundary edge of a property that does isn't bounded on all sides by another parcel. So say I deleted this line it would just unify these two parcels together but if I delete an outside boundary line that doesn't have a parcel outside of it what you're going to notice is that parcel goes away completely.
So that's how you can delete parcels out is you can delete out the entities and basically remove that parcel from your parcels inside of the drawing. So it's um if you need to delete it's different because you can't just select it and choose and hit delete. If I select property 35 and hit delete it doesn't work.

You can try it yourself select an area label click delete you'll notice it doesn't delete. If I select the area label and I look up in this ribbon bar this contextual ribbon bar you'll notice that there isn't an option for delete. There's add labels add tables read number tags properties object viewer isolate parcel properties in any of these you're going to notice that there's not an option for deleting that that parcel.
The way that you delete these parcels is that you go ahead and you remove the boundary information that is making that parcel be an active parcel inside of your drawing.
