David
Here is my code but I have got just one point in the attribute table:
........
.........
mynewshape=OBJ_NEW('IDLffShape',file,/UPDATE, ENTITY_TYPE=1)

mynewshape->AddAttribute, 'lat', 7, 25, $
PRECISION=0
mynewshape->AddAttribute, 'lon', 7, 25, $
PRECISION=0

entNew ={IDL_SHAPE_ENTITY}
for J=0,N-1 do begin
entNew.SHAPE_TYPE = 1
entNew.ISHAPE = fix(randomu(10)*10000)
entNew.BOUNDS[0]=(A[0,j])
entNew.BOUNDS[1]=( A [1,j])
entNew.BOUNDS[2]=0.00000000
entNew.BOUNDS[3]=0.00000000
entNew.BOUNDS[4]=( A [0,j])
entNew.BOUNDS[5]=( A [1,j])
entNew.BOUNDS[6]=0.00000000
entNew.BOUNDS[7]=0.00000000
entNew.N_VERTICES = 1
endfor

attrNew = mynewshape ->GetAttributes(/ATTRIBUTE_STRUCTURE)

mynewshape -> PutEntity,entNew
mynewshape -> SetAttributes, 0, attrNew

OBJ_DESTROY, mynewshape

Cheers
Dave
