B Cell (Geometry Section)
Represents different information in different rows. This table describes the B cell based on the row in which it's located.
| Row | Description |
|---|---|
| EllipticalArcTo |
The y -coordinate of an arc's control point. |
| NURBSTo |
The last weight of the nonuniform rational B-spline (NURBS). |
| SplineStart |
The first knot of a spline. |
| InfiniteLine |
A y -coordinate of a point on an infinite line; paired with x -coordinate represented by the A cell. |
| Ellipse |
A y -coordinate of a point on an ellipse; paired with x -coordinate represented by the A cell. |
Remarks
To get a reference to the B cell by name from another formula, or from a program, using the CellsU property, use:
| Value | |
|---|---|
| Cell name: |
Geometry i .B j where i and j = <1>, 2, 3... |
| Cell name: |
Geometry i .B1 (InfiniteLine and Ellipse rows) |
To get a reference to the B cell by index from a program, use the CellsSRC property with the following arguments:
| Value | |
|---|---|
| Section index: |
visSectionFirstComponent + i where i = 0, 1, 2... |
| Row index: |
visRowVertex + j where j = 0, 1, 2... |
| Row index: |
