_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. These techniques apply to basic CAD programs such as AutoCAD, IntelliCAD, etc.
