Thanks for suggestion...i took a closer look to that shapefile...and i
discovered that it is of type pointZ.....so i proceded in this way..transformed
it in coverage and then back to shapefile from arcinfo workstation...and
surprise it worked.....a am glad that it is ok....anyway I received the
shapefiles from another company and all others layers are ok....i just didn't
tkinked that this could be the cause of the problem..thanks Jacob again
