Hello, I'm new in this comunity and I need some help.

I want to set a rule to avoid the autorouting using the top layer in some components.

I've tried with the querys:

InComponent('U1')

and

InComponentClass('Bottom')

But neither of them worked.

Any suggestion?

Thx a lot.
 

welcome,
you should write like this = ( (InComponent('U1') ) and (InComponentClass('Bottom')) )

regards.
 
Thanks Zula.

I'm sorry I wasn't clear enough. Those were two different attemps.

U1 is already included in Bottom class.

Just in case, I tried your suggestion but it didn't work.

Let me show you with a picture what is my problem:

**broken link removed**

Here is a picture of U1 autorouted. I want to only reach U1's pads with bottom layer tracks. Am I clear?

Update:

I've also tried setting a Pad Class.

Here's how I built the query:
**broken link removed**

And here's how I defined the class: (all the pads of U1)

**broken link removed**

Altium is just ignoring my rules. Any suggestion is welcomed. I need to finish this work today, if possible.


Thanks a lot.
 

ok. iam understand your problem and solved. firsly you have to create a room around the U1. then double click on room and change the layer status to 'bottom layer'.
finally autoroute->room, select the room.
İ have tried and its okey.

regards.

Thx a lot but it didn't work for me. It didn't route at all.

I'm using Altium Designer Summer 09.

Any other suggestion?

i have to ask you last question. Can you route it at all manually??

Yes, without any problem.

If I set it to route the net 'GND' only in bottom layer, it works properly. I'm confused.
