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:

sectorsinclude
integer >= 2
sectors
The number of sectors to include (when include = manual).
sectorvar
String
Created from feature’s tag
Name of variable that evaluates to the sector number, which starts at 0 for the first sector.
spacevarst
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
integer >= 0
0
Starting sector for manual selection of sectors to include (when include = manual).
trans
rot | rotrefl
rot
If sectors is even: Controls whether the transformation performed between consecutive sectors is rotation or rotation and reflection.
