I put multiple structures like this:
……
…
;Create structure for new entity

entnew=replicate({IDL_SHAPE_ENTITY},N[2])

for J=0,N[2]-1 do begin

; Define the values for the new entity
entnew[j].SHAPE_TYPE = 1
entnew[j].ISHAPE = 1470
entnew[j].BOUNDS[0]=(A[0,j])
entnew[j].BOUNDS[1]=(A[1,j])
entnew[j].BOUNDS[2]=0.00000000
entnew[j].BOUNDS[4]=(A[0,j])
entnew[j].BOUNDS[5]=(A[1,j])
entnew[j].BOUNDS[6]=0.00000000
entnew[j].BOUNDS[7]=0.00000000
entnew[j].N_VERTICES = 1

attrNew = mynewshape ->GetAttributes(/ATTRIBUTE_STRUCTURE)
mynewshape -> PutEntity,entnew[j]

mynewshape -> SetAttributes, 0, attrNew
endfor
;;;;;;;;;;;;;;;;;;;;;;;;;;
But still no result
Cheers
