Hi John, If you zoom right in and look closely at your connections you will see that you have a red join dot at the symbol pin where the green wire overlaps the brown symbol pin. Where you have no join dot at a pin, the green wire ends exactly at the tip of the brown symbol pin i.e. there is no overlap. You can see it more clearly if you select the wire and increase the width: ![enter image description here][1] :) [1]: /editor/20160519/573cb92b31026.png

Hi Andy I Zoomed in on one my "No Dot" connects and I don't see the red dot ![enter image description here][1] [1]: /editor/20160519/573cbb139fe6f.jpg I have the wire connect point on pin 3 it stops at the brown edge John

Um, That's exactly what I just described. Now zoom in on one of your pins that *does* have a red dot. In EDA tools, as in old style drawn schematics, you *don't* expect to see a join dot where a wire joins a pin. You *do* expect to see a join dot where a wire crosses a pin.

Hi Andy What I have noticed on some and not all if your run the trace into the componet you will get a "RED" dont. Here is a example. My main concern is when the copper trace is develope is there a difference in the copper layount with "Red" dot or no "Red: dot. ![enter image description here][1] [1]: /editor/20160520/573df77143282.jpg John

As I say, you will get a dot if the green wire *crosses* but does not *end* exactly on the end of the symbol pin. The wire can cross in line with the pin as I indicated in my resistor example or it can cross the pin end at an angle but if it *crosses* over the *exact* end point of the symbol pin then a dot will appear. If the wire *ends* exactly on the end of the symbol pin then there will be no dot. When you are placing wires, if you hover the mouse over a symbol pin end you will see that a grey dot appears at the end of the pin. That is the point that you must wire to in order to make a connection: ![enter image description here][1] The same grey dot appears when you wire to that point: ![enter image description here][2] To answer your question about: `...is there a difference in the copper layount with "Red" dot or no "Red: dot.` No, the dot makes no difference to the connectivity. As long at the wire crosses the `exact` end point of the symbol pin then you have a connection (so beware off-grid components and pins!). However, it is not good practice to draw schematics that have spurious join dots and overhanging wires end as in your examples. It makes a schematic look cluttered, untidy and un-professional. It also makes them harder to read and understand.

Hi Andy Thank you spending the time for the calification on the Read Dot. I really appreciate the support ALl the best John
