A Cell (Geometry Section)

Represents different information in different rows. This table describes the A cell based on the row in which it's located.

Row	Description
ArcTo	The distance from the arc's midpoint to the midpoint of its chord.
EllipticalArcTo	The x-coordinate of the arc's control point, a point on the arc. The control point is best located about halfway between the beginning and ending vertices of the arc. Otherwise, the arc may grow to an extreme size in order to pass through the control point, with unpredictable results.
PolylineTo	The polyline formula.
NURBSTo	The second to the last knot of the nonuniform rational B-spline (NURBS).
SplineStart	The second knot of the spline.
SplineKnot	One of the spline's knots (other than the last one or the first two).
InfiniteLine	An x-coordinate of a point on the infinite line; paired with y-coordinate represented by the B cell.
Ellipse	An x-coordinate of a point on the ellipse; paired with y-coordinate represented by the B cell.

Remarks

To get a reference to the A cell by name from another formula, or from a program, using the CellsU property, use:

Cell name:	Geometryi.Aj where i and j = <1>, 2, 3...
	Geometryi.A1 (InfiniteLine and Ellipse rows) where i = <1>, 2, 3...

To get a reference to the A cell by index from a program, use the CellsSRC property with the following arguments:

Section index:	visSectionFirstComponent + i where i = 0, 1, 2...
Row index:	visRowVertex + j where j = 0, 1, 2...
	visRowVertex (InfiniteLine and Ellipse rows)
Cell index:	visBow (ArcTo row)
	visControlX (EllipticalArcTo row)
	visControlY (EllipticalArcTo row)
	visPolylineData (Polyline row)
	visNURBSKnot (NURBSTo row)
	visSplineKnot (SplineStart and SplineKnot rows)
	visInfiniteLineX2 (InfiniteLine row)
	visEllipseMajorX (Ellipse row)
