Next pick the other endpoint of the line, that is the startpoint of the ARC. _ARC command, enter "C" for center point and pick the endpoint of the line that represents the center point. Now you have the three points needed to draw the ARC. Since this curve is to the right, rotate the line clockwise (meaning you will have to enter a negative angle) the amount of the delta of the curve. Now rotate this line, using the opposite endpoint as the radius point. The image below is how it should look now (the green line is the new one). The opposite endpoint is the center point for the next curve. _LENGTHEN command to set the exact length. Make this line the same length as the radius of the curve. We will assume that this curve is tangent to the previous segment (we'll cover non-tangent curves later).ĭraw a line perpendicular to the previous segment towards the inside of the curve. _LINE command because you need to draw a curve next. Then at the next prompt enter stay in the line command and draw the next segment. If you have XY or Northing and Easting coordinates, you can enter them, otherwise just pick any point in the drawing. Let's start in the lower left (or most southwesterly) corner and work clockwise for this example.įor each line segment, a bearing and distance is given. Start with a line segment if there is one. Below is an example of what you might have. Let's say you have a paper plot or a legal description of a closed boundary. If you have a civil/survey program or add-on, such as Land Desktop, SurvCADD, Eagle Point, etc., then there are built-in tools for entering lines and curves. for the line S32E - align your protractor with the circular side facing east).These techniques apply to basic CAD programs such as AutoCAD, IntelliCAD, etc. If you're using a semi-circular protractor, orient it so that the circular side faces toward the east or west direction of the call (e.g. Place the center of your protractor on top of the dot, making sure that it is aligned with the grid on your graph paper and that north is on top.This will help you remember that this was your starting point, as well as including the markers which will help you possibly match it up with adjoining plats. Beginning at a white oak in Michael King's line). Next to it write down the description of the corner (e.g. Draw a solid dot on your graph paper to indicate your starting point.If your deed description uses poles, rods, or perches, then divide each distance by 4.8 for an easy conversion. If you plan to overlay your plat onto a modern day USGS quadrangle map, then convert all distances to USGS scale and include them on your chart.Check off each line or corner on the photocopy as you work to help prevent errors. Create a chart or list of the calls for easy reference as you play, including only the pertinent information or facts.Land platting experts Patricia Law Hatcher and Mary McCampbell Bell suggest to their students that they underline the lines (including distance, direction, and adjoining owners), circle the corners (including neighbors), and use a wavy line for meanders. ![]() Highlight the calls - lines and corners.Transcribe or make a copy of the deed, including the full legal land description.Pencil and paper will work too - just takes longer. Calculator - Doesn't need to be fancy.Pencil & Eraser - Wood pencil, or mechanical pencil - it's your choice.Patricia Law Hatcher, an expert in land platting, recommends "engineering paper," with four to five equally-weighted lines per inch. Graph Paper - Used only to keep your compass aligned perfectly north-south, the size and type of graph paper is really not important.The only requirement is that it is marked in millimeters. Ruler - Again, easily found in office supply stores.If you plan to do a lot of land platting, then you may want to purchase a round surveyor's compass (also known as a land measure compass), available from specialty supply stores. Protractor or Surveyor's Compass - Remember that half-circle protractor that you used in high school trigonometry? This basic tool, found in most office and school supply stores, is an easy-to-obtain tool for land platting on the fly.
