+A Cornu is a form of curve that uses a mathematical approach to creating a curve between two sets of end conditions.
-\lcont{
+The curve is designed to change curvature linearly along its length - which is the characteristic of a railway easement because it minimizes sudden changes in acceleration towards the center of curvature.
-\u000
+The conditions used at each end are the radius, angle and position.
-\G{png.d/joincornu1.png}
+Cornus can have added constraints in the form of track "pins" that force the curve to smoothly pass through that point while still respecting the end conditions.
+
+Cornus can be used in XtrackCAD to both Join tracks smoothly and form smooth curves that are not joined to other tracks.
+
+Because Cornu are mathematically generated, they can also be regenerated at will and so Cornu Joins have the unique characteristic in XTrackCAD that they remain connected even if the tracks at the ends are moved or even change shape.
+
+Cornu Joins will use whatever space is available - that is their "tightness" (rate of change of curvature) is variable and dynamic. The minimum radius is calculated and will show as an exception, but the acceptable rate of change of curvature is the choice of the designer.
+
+It is not always the case that the Cornu will be the most efficient way to get from A to B - because of its shape it will be the smoothest. If you want to bias the result, you can add TrackPins (\K{cornuTrackPins}).

+\S2{drawDescribe} Draw Object Fields
+
+Some fields are used by multiple types of objects - these are listed below
+
+\dt Line Width
+
+\dd The width of the line for a line, curve or unfilled object can be set. 0 means a pixel width at all scales.
+Other values are the width of the line in scale units.
+
+\dt Pivot
+
+\dd The Pivot control can be set to the start, or the middle or the end, and it applies to the Length and Angle controls
+
+\dt Rotation Angle
+
+\dd Some Draw objects (Polygon, Polyline, Lines, Curves, Circles) can be rotated about their rotation origin in Describe.
+After the rotation completes, the rotation angle will be set to zero, as all the points of the object will be adjusted to thier absolute position in the layout.
+
+\dt Rotation Origin
+
+\dd By default the rotation origin is the Layout origin \{0,0\}.
+By setting a different Rotation Origin, subsequent Rotations will be about that new point. This may be useful when using Draw objects as part of larger collections.
+
+\dt Lock Rotation Origin
+
+\dd For ease of use, the rotation origin can be \e{Relative} to the First Point. If this is done, altering either the First Point or the Rotation Origin will move the both values.
+This value is always set to locked if the Draw origin is non-zero when the \K{cmdDescribe} command is started but can be unset to allow repositioning of the Rotate Origin without moving the object. If the Rotate Origin is set to zero, the Object has an \e{Absolute} origin.
+
+\dt Layer
+
+\dd The object can be moved between layers
+
+\dt Color
+
+\dd The color of the line or the fill can be set
+
+\S3{drawDescribeStr} Straight Line Objects
+
+\dt End Pt 1
+
+\dd For Straight Lines the object has a starting position (or first point) - altering this value causes the whole object to move relative to the layout origin.
+
+\dt End Pt 2
+
+\dd Straight Lines have a second point, altering this, moves just that end of the line, altering its length as needed.
+
+\dt Angle
+
+\dd Straight Lines have an angle - this is the angle between the two points, altering this moves End Pt2.
+
+\dt Length
+
+\dd The Length control can add to the start or end or both of a Line object depending on the setting of the Pivot control.
+
+\S3{drawDescribeDim} Dimension Line Objects
+
+\dt Size
+
+\dd The size of the arrows and text can be set to Tine, Small, Medium or Large.
+
+\S3{drawDescribeBench} BenchWork Objects
+
+\dt Lumber
+
+\dd A set of standard dimensions of timber sizes that are often used to construct benchwork. They are specified in "nominal" dimensions but drawn in "actual" dimensions.
+
+\dt Orientation
+
+\dd The timber can be orientated "On Edge" which will draw the smaller dimension or "Flat".
+
+\S3{drawDescribeCurve} Curved and Circle Objects
+
+\dt Center
+
+\dd Curved Lines and Circles have a center. Moving this moves the object.
+
+\dt CW Angle and CCW Angle
+
+\dd Curved Lines have an angle relative to the center that the arc starts and and one where it ends
+
+\S3{drawDescribePoly} Polygon Objects
+
+\dt Fill
+
+\dd Some draw objects (Circles, Polygons) can be filled or emptied - note that Polylines can not be filled - they have to be closed first.
+
+\dt Open
+
+\dd Polygons can be opened to become Polylines or Polylines closed to become Polygons using Describe.
+
+\dt Point Count
+
+\dd Polygons and PolyLines have a count of nodes - this is read-only.
+
+\dt Height and Width
+
+\dd Rectangular Polygons have two properties that can alter the Height and Width of the Polygon
+
+\dt Line Type
+
+\dd Straight and Curved Lines, PolyLines, Polygons and Structures can be drawn with dotted, dashed, dash-dotted and dash-dot-dotted lines.
+
+\S3{drawDescribeText} Text Objects
+
+\dt Text Angle
+
+\dd For Text objects, the Text Angle determines the angle the text is rendered at. This is independent of the rotation of the starting position which is gained from the Rotation Angle and the Rotation Origin.
