Red dot difficulties, is there a secret ?

2031 25

This might be a double post, but I could not see my prior comment from about an hour ago My problem is the red dot, that seems to haphazardly connect on some junctions, and totally refuses to connect on others. It does not appear in Place as a part, so should occur when the mouse click finishes, but it does not occur correctly as it should. I have tried in the example of a simple 5mm pitch connector block to connect the 2nd junction over 170 times Perhaps if it can be explained why, might be helpful, if others are similarly stuck unable to proceed to pcb design, seemingly forever correcting errors that the program appears to be making I have even tried copying the red dot, and pasting it, but that does not work either. What is the secret in getting red dots reliably on all junctions please![Screenshot from 2021-01-14 13-38-56.png](//image.easyeda.com/pullimage/JwJe7BgpMw7HDl0D8EkFG5gn2xpysqHTlqOiMD60.png) Thank you

Further,![Screenshot from 2021-01-14 17-07-13.png](//image.easyeda.com/pullimage/RJKisiCoF2oStuOvKSSfOJ7S9fZE8IsM3eCwua29.png) Here is an image of some of the net errors, showing P2_2 , which when pressed momentarily creates a crosshair. ( I have never liked the crosshair which I think is the true cause of the difficulty as it initially does not move the line, and requires many attempts to create a line, which then creates further errors because it does not move naturally - compare easy EDA to early versions of Oregano which is heaven in comparison - but that's another story ) The crosshair shows a red dot being needed, but is seemingly impossible to then make it create the red dot, which asks can one ignore the net error ?

Thank you, but that provides no answer, and just reinforces that there is no way to join with a red dot, one spot to the next, and to properly avoid net errors.

Your screenshot would be more help if it showed more pins, connections and the Prefix of the Schematic Symbol. I suspect you are using a User Contributed Schematic Symbol and that you did not check it before using as advised. Find, Select and Edit the Schematic Symbol from the Library tool that you are having problems with in the Symbol Editor. Check that the connection hotspots of the pins all face outwards, away from the symbol as shown in Tutorial about Symbol Libraries. Also tidy it up to make the pins all the same length.

Hi ![Screenshot from 2021-01-14 22-04-18.png](//image.easyeda.com/pullimage/F6DicjtNKGYtma3w6XA57XSIRdSjHonFDjBWXbLZ.png)No actually its the part in the EElib R-M-2.54 , in the bottom left corner ![Screenshot from 2021-01-14 22-13-34.png](//image.easyeda.com/pullimage/LvwHY6OLgqsaFqN9aqwuSiPfeDEuWpbVwSxj86lR.png) but looks like that is the problem, as I found a larger connector that created red dots straight away seen here: Compare CN1 to P2 one connects the other doesn't i will search through other connectors to see if any will work. Thank you

This red dot only appears at: 1, wire and wire connected 2, pin and pin connected 3, pin vertical connected with wire if the pin wiring the wire at the same direction it will not show up. your images are normal behavior

Hi! There is a way that you don't need to worry about red dots, just use net ports and problem solved! Regards, Markus Virtanen HW / Electronics Designer

But if you need wire and wire connected which is normal , ( otherwise open circuit ) the red dots are essential. I have found though a method that works, defining the issue as being the crosshairs ( my old enemy the crosshairs again - sorry ) The method is to create a wire inaccuracy at the joining point, ![Screenshot from 2021-01-14 23-46-16.png](//image.easyeda.com/pullimage/UTmO0srk7T82Tpj2L6K2ulUC5fhnVLbkuym6qX5I.png) as we can see red dots appear when a deliberate wiring inaccuracy occurs at the end, compare R3-R7 to R11

Sorry folks, a few of the same post, my screen showed a network error. @ Markus_ee I will look into net ports Thank you

Here is a few of my projects where I use net ports to connect components together between different functional blocks: [https://easyeda.com/markus_jidoka/delay-off-timer](https://easyeda.com/markus_jidoka/delay-off-timer) [https://easyeda\.com/markus\_jidoka/400v\_geiger\_tube\_psu\_v1\-0](https://easyeda.com/markus_jidoka/400v_geiger_tube_psu_v1-0) -Markus

@cdrhd1500, I should have looked more closely at your setup. I think the problem may well be that your version of Firefox is long out of date. You may find the problem goes away if you update your copy of Firefox. Otherwise try installing the latest version of Chromium (or Chrome)

I'm finding the same problem with the Desktop version. Been happening last few days and only way to get a joint is to delete all the wires and redo them. Even that doesn't always work

I have just done a new schematic and have the program not creating any red dots at all, and then every junction has been redone trying to get the red dot , I am wasting hour after hour with no ability to create reliable junctions. My Mozilla is up to date. It is very frustrating as every effort is being made to make components connect at the schematic, but nothing connects.

@cdrhd1500, Is this web or Desktop?

I have also updated to the latest version which was quite straight forward to do, but it also did not fix the inability for components to join when the mouse is let go at the desired location. This IMO needs to be immediately looked at as in my estimate only 2 perhaps 3 % of those trying to do schematics and pcb design are successful, with 97% just giving up because the program is so hard to use. The problem is the mouse movement and connecting parts , otherwise Easy EDA is a clear winner - if this can be addressed.

@andyfierman I am using web at the moment, due to the difficulty of making the Linux version work , although with a lot of effort it does work, I would rather just be getting along with trying to make a pcb.

@cdrhd1500, I can't reproduce this behaviour. Can you colpy part of your private project exhibiting this behaviour into a public project? Such as in your image: ![Screenshot from 2021-09-17 17-57-40.png](https://image.easyeda.com/pullimage/D4NBGHduqxonH9U8uigQKCWhaNHurNIZDnqcVG0J.png)

Here is a super simple schematic, none of the lines are linking to components , and are creating every point to be a net error ![Screenshot from 2021-09-18 10-23-51.png](//image.easyeda.com/pullimage/VaV3bwE81bNm56it5e33QBdpB2kZ5P6pxfjuhHGn.png)

@andyfierman Can you please draw the same schematic where all lines connect with red dots and create no net errors, and if so reveal how you did it.

@cdrhd1500 please fresh the nets folder at left side Design Manager， if still not show the junction, please select all circuits and move by mouse or direction key, it will generate the junction automatically. if not, please export this file as EasyEDA source and send to support(AT)easyeda.com

You should not use BUS to connect parts, you should use WIRE

@UserSupport, Well spotted. I had wondered why the wires were so wide. @cdrhd1500, Sharing a simple public project, as suggested in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) would have allowed this mistake to be diagnosed months ago. :)
