Hi,
This is the first time I will be using Routing and just watch videos on youtube it's quite fun to create. But, they have only used 1 pipe size. Now my query is what is the best approach for a Piping ISOmetric that has 3 different Pipe sizes (10", 3" & 2") and how do you insert those other pipe sizes?
Many options here:
Generally fittings are used to determine pipe section diameter. If you need to change dia, use appropriate fitting or penetrate.
