EASTING (X)

6272528.9745′

NORTHING (Y)

1930872.7578′ 2) Create a new layer

3) Insert the POB Block at your specific Coordinates

• Browse = Select the POB_Block.dwg file, and click open
• Insertion point = Uncheck Specify On-Screen, and Type in the following:
  • X: type in your easting coordinate (without the feet symbol)
  • Y: type in your northing coordinate (without the feet symbol)
  • Z: type in “0” (without the quotations)
• Scale = Uncheck Specify On-Screen and Type in 1 for X, Y and Z
• Uniform Scale = Uncheck
• Rotation = Uncheck, and the angle must be “0”
• Block Unit = Unit = Feet and Factor = 1
• Explode = Uncheck
• Click OK

1) Start at the center of the POB_Block and enter each direction and distance (shown below) to traverse around the land to form the boundary.

2) Click the Layer Properties manager to create a new layer called C-Boundary in the Project Layers Filter. Set the color to red and set it as your current layer.

3) Review the following steps for drawing a boundary in AutoCAD

4) Use steps 1 through 6 above to draw your property boundary from the following legal description

Beginning Legal Description at the Point of Beginning;
thence bearing N 90°0’00” E a distance of 4500 feet ;
thence bearing N 00°00’00” E a distance of 4500 feet ;
thence bearing N 90°00’00” W a distance of 4500 feet ;
thence bearing S 00°00’00” E a distance of 4500 feet ;
to the point of beginning to create the outer square shape of the property.

Furthermore, use a circle with the radius of 3181.98 to construct the inner octagon shaped boundary that will be used for your design. (removed on 2/25/21)

Note:

The goal of a legal description is to identify a boundary. On rare occasions, due to various natural and human reasons, things may not turn out perfect. When that happens, you’ll have to dig a little deeper and research other maps and documents that may reference the property to develop an appropriate solution for the discrepancy. Keep in mind that when you are recreating a boundary, you must be aware of and understand the surveyor’s intent.

5) Create a new layer called C-WORKING in the Project Layers Filter

• • Change the color of the C-WORKING Layer to 163, 88, 126 and set it as your current layer.

6) Within the Layers Manager:

Freeze the following Layers:

C-POB

V-Topo-Contour-Minor

V-Topo-Contour- Major

Unfreeze the following Layers:

V-Topo-Tin-Surface

V-Topo-Contour-Text

1) Turn your boundary into a closed polyline:

• • Type PEDIT, and press Enter
  • Click on any of the boundary lines, and type Y and press Enter
  • Click JOIN, and select each of the four (4) eight (8)(updated on 2/25/21) boundary lines and press Enter
  • Click CLOSE (if given as an option), and press Enter
  • Type MO, press Enter
  • Select the closed boundary and confirm that the Elevation is set to “0”

2) Offset your boundary

• • Tyle Offset
  • Type 250, and press Enter
  • Select the boundary, move your cursor anywhere outside of the boundary, and press the left mouse button again to execute the command
  • Type MO, press Enter to bring up the properties menu
  • Select the outermost boundary, and change the Linetype to Phantom
  • While the outermost boundary is still selected, type PEDIT, click Width, press Enter, type 45 and press Enter

3) Associate the Boundary

• • From the Toolspace panel
  • Expand “Surfaces”
  • Expand EXISTING Surface
  • Expand “Definition”
  • Right click on “Boundaries”

• • Select “Add”
  • Enter a name for your boundary
  • Type = Outer
  • Non-destructive breakline = Check
  • Distance = 1.0’
  • Click OK

Now, Click on the outermost boundary (the one that was created from the Offset set above)

This screenshot is only an example. Your boundary will be different

Notice that the surface has been trimmed to only show what’s within the offset polyline. This is very important because you do not want to overwhelm AutoCAD or the computer by processing unneeded information.
