How to Create Parcels in AutoCAD Civil 3D?

Understanding Parcel Creation in AutoCAD Civil 3D

Creating parcels in AutoCAD Civil 3D is an essential skill for professionals in civil engineering and land design. This process allows you to efficiently define and manage parcel boundaries for real estate or development projects. Here’s how to create parcels step by step.

Step 1: Preparing Your Drawing

Before initiating the parcel creation process, ensure that the AutoCAD objects you plan to convert into parcels are free from any drawing errors. This includes checking for overlapping lines, open polylines, and other inconsistencies that could affect the parcel’s integrity.

Step 2: Accessing the Parcel Creation Tool

1. Navigate to the Home tab.
2. Look for the Create Design panel.
3. Click on the Parcel drop-down menu.
4. Select Create Parcel From Objects. This action will activate the tool for creating parcels based on the selected objects in your drawing.

Step 3: Selecting Objects for the Parcel

With the parcel creation tool activated:

1. Click on the lines and polylines that outline the boundary of the parcel you wish to create.
2. Ensure that you have selected all the relevant objects, including the outer boundary and any internal divisions if required.
3. After selecting, press Enter to proceed.

Step 4: Finalize the Parcel Creation

After making your selections, the Parcel Creation dialog box may prompt you to input additional details or settings related to the parcel, such as naming conventions or style specifications. Confirm your choices and finalize the process by clicking OK or Apply.

Utilizing Parcel Objects

Parcel objects are a vital feature in AutoCAD Civil 3D, essentially acting as containers for real estate lots and boundaries. Each parcel consists of components such as:

• Boundaries: Closed polygons that define the extents of the parcel.
• Nodes: Points where line segments meet.
• Segment Types: Including straight lines and curves, providing flexibility in design.

Modifying Parcels

Splitting a Parcel

To split an existing parcel:

1. Open the Data Table and locate the parcel you want to modify.
2. If needed, hide the Data Table to focus on your drawing.
3. Navigate to the Feature Edit tab.
4. Click on the Split/Merge panel and choose Split Feature.
5. Confirm that the feature is checked out and then close the notification.

Deleting Parcels

If the need arises to delete a parcel:

1. Select the label of the parcel segment you wish to delete. A correct selection will highlight the text and its anchor point.
2. Press the Delete key to remove the selected parcel.

Creating Profiles and Additional Features

You can also create profiles related to parcels, which are vital for understanding elevations and site grading:

1. Go to the Home tab.
2. Locate the Profile drop-down in the Create Design panel.
3. Select Quick Profile Find and follow the prompts to select relevant points in your drawing.

FAQ

1. What is a parcel in AutoCAD Civil 3D?
A parcel in AutoCAD Civil 3D is a defined area that represents real estate lots. It is characterized by closed polygon boundaries and consists of nodes and line or curve segments.

2. Can I create multiple parcels at once?
Yes, you can create multiple parcels simultaneously by selecting all the relevant objects in your drawing before finalizing the parcel creation process.

3. How do I convert a parcel into a polyline?
To convert a parcel into a polyline, select the parcel, navigate to the appropriate tools in the ribbon, and use the conversion features available under the parcel editing options.
