How to Plot Lot Bearings in AutoCAD?

When it comes to accurately representing lot bearings in AutoCAD, it is essential to have a clear understanding of the process. Whether you are a surveyor, civil engineer, or architect, properly plotting lot bearings is crucial for precise land development and design. In this article, we will provide you with a comprehensive guide on how to plot lot bearings in AutoCAD, covering all the essential steps and techniques.

Understanding Lot Bearings

Before diving into the technical aspects, let’s first clarify what lot bearings are. In land surveying, a lot bearing refers to the direction of a property line measured in degrees, minutes, and seconds clockwise from true north or south. It helps define the boundaries of a lot and is critical for accurately representing land parcels on drawings.

Starting with a Basemap

To begin plotting lot bearings in AutoCAD, it is essential to have a basemap or a survey plan of the area. This can be obtained from a surveyor or by digitizing existing paper drawings. Once you have the basemap in a compatible format (such as DWG or DXF), you can proceed with the following steps.

Setting Up AutoCAD

1. Open AutoCAD and create a new drawing or use an existing one.
2. Ensure that the drawing units are set correctly to match the units used in the basemap. This can be done by accessing the “Units” command and adjusting the settings accordingly.

Importing the Basemap

To import the basemap into AutoCAD:

1. Use the “Import” or “Attach” command to bring the basemap into the drawing.
2. Adjust the scale and position of the basemap to align it with the existing AutoCAD drawing using the appropriate scaling and moving tools.

Adding Lot Boundary Lines

Now that the basemap is imported, you can start plotting the lot bearings by adding lot boundary lines. Follow these steps:

1. Use the “Line” command to draw lines representing the lot boundaries. Make sure to align the lines with the basemap accurately.
2. To specify the direction of each boundary line, you can use bearings. In AutoCAD, you can enter the bearing values in the format of degrees, minutes, and seconds or as decimal degrees.
3. To draw a line with a specific bearing, use the “Polar Tracking” feature to lock the direction. This feature allows you to draw lines at specific angles relative to the previous line.

Annotating Lot Bearings

To make the plotted lot bearings clear and understandable, it is important to annotate them properly. Here’s how you can do it in AutoCAD:

1. Use the “Text” command to add text labels next to the boundary lines.
2. Indicate the bearing value and the line’s length, if relevant, to provide comprehensive information.
3. Adjust the text size, font, and alignment to ensure readability.

Creating a Bearing Table

To summarize the lot bearings and provide a comprehensive overview, you can create a bearing table in AutoCAD:

1. Use the “Table” command to insert a table into the drawing.
2. Define the required number of rows and columns to accommodate the bearing information.
3. Fill in the table with the lot numbers, corresponding bearings, and any additional relevant data.
4. Format the table to enhance its visual appearance, such as adjusting cell borders and text formatting.

Adding Dimensional Information

In addition to lot bearings, it is often necessary to include dimensional information, such as distances between lot lines or between lot corners. To achieve this in AutoCAD:

1. Use the “Distance” or “Dim” command to measure and display the distances between different points.
2. Place the dimensions near the respective lines or corners to provide a clear representation of the lot’s layout.

Checking Accuracy

After plotting lot bearings in AutoCAD, it is crucial to verify the accuracy of the drawn lines and annotations. Here are some tips for ensuring accuracy:

1. Double-check the bearing values and distances against the survey plan or other reliable sources.
2. Use AutoCAD’s measuring tools to verify distances and angles.
3. Compare the plotted boundaries with any available georeferenced data or aerial imagery for additional validation.

FAQ

1. How do you read a lot bearing?

To read a lot bearing, you need to understand the format in which it is typically represented. A lot bearing is measured in degrees, minutes, and seconds clockwise from true north or south. Here’s a step-by-step guide on how to read a lot bearing:

1. Start by identifying the starting point of the lot bearing. This could be a corner of the property or any other reference point.
2. Look for the bearing value associated with the specific lot line you want to read. The bearing value will consist of three components: degrees, minutes, and seconds.
3. The degrees represent the larger unit of measurement, ranging from 0 to 360. It indicates the direction of the lot line in relation to true north or south.
4. The minutes represent a smaller unit of measurement, dividing each degree into 60 parts. They refine the direction of the lot line within the degree range.
5. The seconds further divide each minute into 60 parts, providing more precise information about the direction.
6. Read the bearing value in a clockwise direction from true north or south. For example, if the bearing is 45 degrees 30 minutes 15 seconds, it means the lot line is oriented 45 degrees clockwise from true north or south.
