# Node Sorting Operators

A set of MeshPoints must sometimes be sorted, usually to reduce a selection. SortingOperators are objects that can be used to execute this sorting operation.

 SortByX0() Sort by X0 in increasing order SortByY0() Sort by Y0 in increasing order SortByZ0() Sort by Z0 in increasing order SortByDX0() Sort by X0 in decreasing order SortByDY0() Sort by Y0 in decreasing order SortByDZ0() Sort by Z0 in decreasing order SortByPos0(lock) Sort in increasing order by an initial coordinate in a given direction (lock = TX, TY or TZ) SortByKsi0(curve) Project nodes on the curve then sort in increasing order by projected curve abscissa SortByDist0(x,y,z) Sort nodes by increasing distance from the point of coordinates (x,y,z) SortByNo() Sort nodes by increasing user number InverseSOp(sOp) Inverse the effect of the sorting operator to which it is applied CombineSOp(sOp1, Sop2) Combine 2 sortings Operators (applying SOp1 then SOp2)
