Sector2D, Sector3D
Create a 2D or 3D sector symmetry dataset.
Syntax
model.result().dataset().create(<dtag>,"Sector2D");
model.result().dataset().create(<dtag>,"Sector3D");
model.result().dataset(<dtag>).set(property,<value>);
model.result().dataset(<dtag>).run();
Description
model.result().dataset().create(<dtag>,"Sector2D") creates a 2D sector symmetry dataset feature named <dtag>.
model.result().dataset().create(<dtag>,"Sector3D") creates a 3D sector symmetry feature named <dtag>.
This dataset takes data from another datasets and expands it using sector symmetry around an axis.
The following properties are available for Sector 2D and Sector 3D:

genpoints
double matrix
{{0, 0, 0}, {1,0,0}}
When method is twopoint: The coordinates of two points on the symmetry axis. Available for Sector3D.
include
all | manual
all
Use all sectors or specify manually which ones to include.
method
twopoint | pointdir
twopoint
Decides if the line should be specified by two points or through one point and a direction. Available for Sector3D.
mode
integer
0
If sectors is odd or trans is rot: The azimuthal mode number use to transform the solution’s phase between sectors.
pddir
String array
{"0","1"}
When method is pointdir: The direction in which the symmetry axis points. Available for Sector3D.
pdpoint
String array
{"0","0"}
When method is pointdir: The coordinates of a point on the symmetry axis. Available for Sector3D.
point
double array of length 2
{0, 0}
The coordinates of the symmetry axis. Available for Sector2D.
reflaxis
String array of length 2 in 2D and length 3 in3D
{"1","0"} in 2D, {"1","0","0"} in 3D
If trans is rotrefl: The direction in which the reflection axis/plane (for 2D and 3D respectively) points.
sectors
String
2
The number of sectors as an integer >= 2 or variable.
sectorsinclude
String
sectors
The number of sectors to include when include is set to manual. It can contain a variable for the number of sectors.
sectorvar
String
Created from feature’s tag
Name of variable that evaluates to the sector number, which starts at 0 for the first sector.
spacevars
String array of length 2 in 2D and length 3 in 3D
Created from feature’s tag
Names of variables that evaluate to the space coordinates in the coordinate system after sector symmetry expansion.
startsector
String
0
Starting sector for manual selection of sectors to include when include is set to manual. It can contain a variable for the starting sector.
trans
rot | rotrefl
rot
If sectors is even or a global expression: Controls whether the transformation performed between consecutive sectors is rotation or rotation and reflection.
