IO

Type of cs

1 = input cs 2 = output cs

SN

Sequence Number

Pipes have two pairs of CS with SN = 1 and 2. The sequence numbers can be assigned to the pair INPUT/OUTPUT_POINT_1 or INPUT/OUTPUT_POINT_2 arbitrarily.

In fittings with two openings, SN = 1 is the pair at the opening with bigger diameter, SN = 2 is the opposite pair. If the openings are the same size, SN = 1 is the pair at the opening with male connection and SN = 2 is the pair at the opening with female connection. If the  fitting has no male/female connections, the sequence numbers are arbitrary.

Laterals has SN = 3,  the pair at the lateral opening, SN = 1 is the pair at the opening near lateral opening and SN = 2 is the pair opposite to pair with SN = 1.

Tee has SN = 3 as the side opening pait, SN = 1 is opening with bigger diameter and SN = 2  is the pair opposite to pair with SN = 1.

Ys has SN = 1 the pair at the opening opposite to both branches which get SN = 2 and SN = 3.

Crosses have SN = 1 is the pair at the opening with biggest diameter, SN = 2 is the pair opposite to pair with SN = 1, SN = 3 is the pair at the opening with bigger diameter from the remaining openings and SN = 4 is the last pair.

CD
