manual routing in restricted area

Hi, I want to manually attach a route to a component around which a tRestricted Area is placed.
I have tried everything possible and can't do it. Here is a picture of what it looks like.

Does anyone have a tip for me?

You have to switch to "Ignore violators mode".
Look at the bottom tool-bar, right side.
Or shortcut Cmd-I (Mac).

Just to add to @jesper8W75R 's comment.

 

His recommendation will work, but the fact that you are running into this indicates that the library part was made incorrectly. So if you need to get it done, go with Jesper's solution but long term the real solution is to fix the bad library part.

@jorge_garcia2 - I've also hit this (with an imported library part) and my instinct (coming from kicad) is that the behaviour is unexpected. I get that Fusion is different and I just need to learn to adapt, but 'your part is broken' doesn't help me with that learning. And the Fusion documentation is inadequate so we rely on you guys to help with our learning.

 

Please can you expand on your post by explaining why it is wrong to use tRestrict for this purpose, and what other strategies there are to define a restricted area. Restricted zones should be defined around some devices to ensure that nothing accidentally routes through/close to the footprint, but I do still need to be able to attach to the pads.

 

Is there a video that discusses this kind of footprint attribute? I found the all layers description in the help but it is not all that informative to be honest.

Hi @jonrbloom,

 

I hope you're doing well. In Fusion Electronics there are 3 Restrict layers that serve as no route features for the autorouter and assisted routing modes. These are tRestrict(For the top layer), bRestrict (For the bottom layer) and vRestrict (No vias).

My guess here is that when you made this part, you were trying to make what is some programs is called a courtyard (I don't know what KiCAD calls it), basically a fence to make sure components can't get to close to each other. If that was the intent then you could draw those features on the keepout layers which are Fusion's version of a courtyard layer.

By enclosing a part using a rectangle on the Restrict layers you have effectively made the part unroutable because any areas covered by the Restrict layers are no route zones. If you don't want traces to go under the pad just shrink the restrict area so that it only covers the area you don't want traces to go through and leave the pads exposed. That's all there is to it.

 

Let me know if that makes sense or if you have any other questions.

 

Best Regards,

Thank you @jorge_garcia2, this helps a lot. The symbol I hit this with was imported from one of the auto-symbol websites (symacsys I think), not one I created, but this would be auto-generated I can well believe this was simply incorrect.

 

I will experiment with the keepout layers to get a better understanding for next time. Appreciate the summary.
