I need to select Centerline Alignment only ( filter ) from selection?

[y.awwad]

I select one Alignment and then select similar but all alignments selected

(ssget (list (cons 0 "AECC_ALIGNMENT")))

I need to filter the selection to (Centerline Alignment only )

@hosneyalaa 

I already selected all alignments .. but I need to filter the selection to (Centerline Alignments only )

Not offset alignments

Not curb return alignments

FILTER BY NAME

[y.awwad]

Filter Civil 3D Alignment By Type

Same as filtering Line (ssget (list (cons 0 "LINE"))) or (ssget (list (cons 0 "POLYLINE"))) or (ssget (list (cons 0 "LWPOLYLINE"))) .. Filter by type no names
