net class manual routing

[aleksazr]

Hello everyone, I'm new here.
I have some 10 months of Altium experience, plenty with older Protel.

Question:

Say I have 3 nets: 5V, 5VA and 5VB.
I want to route 5VA and 5VB separately, then join them in some point(s) to 5V.

 I've created a net class (CLASS5V) with all 3 nets so I can create a rule allowing
 CLASS5V to be short-circuited to itself.

 That works great, I can route all 3 nets together and join them... but Altium still thinks
 some points are not connected - even though they are.

 For example, I have two vias of 5VA net connected together with a 5V track,
 and Altium doesn't think they are connected... it still shows a ratsnets.

 What is the Altium's approach to this kind of routing?

I can't think of any solutions offhand. Your "sub" nets should probably be contiguous, e.g. connected end-to-end and only shorted to other nets at one point. There might be a way to disable "net routed" checks, but that's a pretty big hammer.

I've found one way... if anyone is interested.

1. route the board until almost done and you are unsure if it is completed or not.
2. copy the PCB file and open the copy in Altium.
3. Design > Netlist > Configure Physical Nets...

repeat steps 2 and 3 until finished.

Setbacks:
1. Jumpers are not taken into account.
2. Nets that are no longer in use are not deleted from the netlist. (not sure if this bothers me or not)

Cheers!
