Utility Network analyst: Similar tasks!

I'm not sure about the critical difference between:

I) path tasks:

1.Find path upstream

2. Find path

II) upstream tasks:

1. Find path upstream

2. Find upstream accumulation

3. Trace upstream

III) Trace and Find:

1. Trace upstream

2. Find path upstream

thank you in advance,

regards

Jamal

1.Find path upstream

You place a flag and it finds the direct path to the SOURCE using weights2. Find path

You place two flags and it finds the direct path between the two flags using weightsII) upstream tasks:

FIND Paths will use any weights you have built into your Geometric Network. Trace will simply find the most direct route.1. Find path upstream

2. Find upstream accumulation

3. Trace upstream

III) Trace and Find: S

ame answer. Trace finds the most direct route, FIND uses the path of least resistance.1. Trace upstream

2. Find path upstream
