To elaborate: It is my understanding when sizing springs with the "release for hanger selection" checked, AutoPIPE treats the anchor as being free (in the selected degrees-of-freedom) during sizing. When they install the pipe if the degrees-of-freedom at the anchor does not match how the spring was sized, the applied cold load will not match the preset cold load. If the difference in load is large, it could be very difficult to remove the spring blocks. Thanks, Sean
