I drew a proposed sewer network to be surveyed and would like to know if there is a way of deteriming the total length of this. Drew it as polylines and tried to join them but it wouldn't. At the moment I have to do it manually.
If you drew it as a polyline, then you should be able to list the components and it should give you a total length. If the polylines are discreet and not joined, then try using the fillet command to join them.
