[SOLVED] Ratsnets desition make based on different layer

truhlik_fredy

Hello everybody,

 

I'm wondering if following is possible. I need to have a ratsnets being made based on top layer, but the polygon itself needs to be stored in a different layer. I need to automate process with cam and I need to have it stored under different layer to apply different settings to the job. But the ratsnets needs to be decided on the top layer.

 

Thanks in advance for any hints or ideas.

 

PS: if it's possible in any specific version I don't mind upgrading/downgrading.

    Hi Anton,

     

    I think the initial confusion was caused by you referring to referring to ratsnest when you are really just talking about processing polygons. Ratsnest is exactly as I said it was above in my other post, it has a side effect that it triggers the processing of polygons which uses the DRC defined clearances as well as the properties specified for the polygon to fill the polygon without violating any defined rules.

     

    So, what you are asking for is if there is a way to ensure that a particular polygon has gaps corresponding to traces on another layer, in this case the top layer. Unfortunately traces on the top layer aren't going to violate any rules defined in the DRC or the polygon so it's not going to be able to automatically clear the area of the polygon from underneath the traces. The only way to do this is to manually add additional polygons defined as "cut out" on the same layer as your polygon, underneath the traces you wish to avoid having your polygon fill underneath.
