Missing junction in Net

[NikosAntoniou]

Hi everyone,

I have some missing junction error in my schematic I cannot figure out the reason despite the fact that they seem to be connected.

The Auto set junction is enabled

I've tried to delete and redraw the nets

I confirmed that the nets at the "junction" have the same name

In the board I have routed the trace without any problem

Which tool did you use to draw the nets?

This may be less of a common mistake with recent versions of Eagle but, in the old days, there was a tool called "wire" which allowed you to draw green lines that formed nets but was absolutely the WRONG tool for doing so. The correct tool is called "net". If you draw with the NET tool and start or finish on an existing net, it automatically adds the junction. The wire tool doesn't because it's intended for drawing (non-meaningful) lines on other layers. Its name was just a mistranslation from German.

As a quick fix for your existing schematic, you can manually add the missing junctions with the junction tool, as long as you aren't breaking the golden rule that everything on a schematic must be on a 0.1" grid.

Edit: Oh, and having re-read your post, it's not entirely clear whether you are aware that the junction is that green blob that you can see (badly placed) on pin 12 of the relay. You should have such a dot on all junctions, otherwise it's just two nets crossing.

Thank you for your answer @one-of-the-robs 

Well I figure out that I have got break the golden rule of 0.1'' grid as you mentioned. I aligned the parts with the 0.1'' grid and redraw the nets.. The problem now has been solved. the But still, don't understand why this is a problem once there is actually connection between the lines..

Using the "net" function instead of the "wire" function for me worked! Thanks
