To Create Curves Between Two Lines

The selected lines are trimmed to the resulting point of curvature (PC) and point of tangency (PT).

You can use the Curve Calculator to determine the values required for defining the curve.

1. Click Home tabDraw panelCurves drop-downCreate Curves Between Two Lines Find.
2. Select the first tangent.
3. Select the second tangent.

   The following prompt is displayed:

   Select entry [Tangent/External/Degree/Chord/Length/Mid-ordinate/miN-dist/Radius] <Radius>:
   

4. Enter one of the following options to define the curve:
   • Enter Length, or L, and then enter the length or pick the distance in the drawing.
   • Enter Tangent, or T, and then enter the tangent length or pick the distance in the drawing.
   • Enter External, or E, and then enter the secant length or pick the distance in the drawing.
   • Enter Degree, or D, to define the curve by degree of curve.

     The following prompt is displayed:

     Enter degree of curve (Arc), or [Chord]:
     

     Enter the degree of curve in DD.MMSS format using the Arc or Chord option.

     Use the Chord option if the curve is a railway curve. For a railway curve, the degree of curve is the angle at the center of a circular curve subtended by a chord of 100 units.

     Use the Arc option if the curve is a roadway curve. For a roadway curve, the degree of curve is the central angle subtended by a circular arc of 100 units.

   • Enter Chord, or C, and then enter the chord length or pick the distance in the drawing.
   • Enter Mid-ordinate, or M, and then enter the distance or pick the distance in the drawing.
   • Enter miN-dist, or N, and then select the end of an existing curve. Then enter the minimum distance between the end of the new curve and the point selected on the existing curve.
     Note:

     The command sets the Object Snap to END for this prompt. The point you select does not have to be on an existing curve; it can be any point along the adjacent tangent.

   • Enter Radius, or R, and then and then enter the radius or pick the distance in the drawing.
