Hi all
I do not know why easy PC is deleting the link between two track on the PCB when I delete one routed track...
Routing is about trying differents way through the board, if I have to reforward the design change each time I make a mistake this will get really irritating at the end of the day!
Any recomandation?
Thank you
Rémi

For a start; if you do something which you don't like, there's always "undo"! It's default keyshort is Ctrl-Z.
If you delete a track, it will delete the connectivity. What you should probably be doing is 'unroute track' or 'unroute track segments' to try another way around.
I hope this helps.
Best wishes,
Olga.

| Thx Olga but I thought the software would follow the common sense and use the delete key to unroute the track a shame! |

No, delete means exactly what it says. On the right click menu there are a number of options in the 'Net' menu, including the rather drastic 'Unroute Net'.
If you use any of these regularly, perhaps it's worth setting up your own hot key for the function under the [Settings], [Customise], 'Keyboard' tab. |

Indeed... otherwise things would get confusing, if 'delete' did different things at different times.

Verb. sap. Do not do this on a power/ground net, unless you *really* mean it! If you do... that Ctrl-Z is your friend!
(Can you tell that this has happened to me...?!  )
Best wishes,
Olga.
<edit> Another thing to watch for is if you have a component selected & you ask for 'unroute nets'... it *will* unroute your power & ground nets as well, unless you un-select these pins! (another from me there! Only the once, though  ) |

I dont really agrea on that!
To me on 99.999999% of the time I use the link between track created by the schematic and I would never edit the link (netlist) in the PCB manually...
Then it would appear to me ( and to many other PCB software like Proteus) that delete means unroute track by default and not delete the link; that, to me should never be used
Or tell me if you use that regularly?

Having 'grown up with' Easy PC since it was a DOS-based PCB-Layout tool only (no schematic), when it didn't have ratsnests at all, I guess I've got used to how it works & how best to use it.
With that in mind, it's second nature to me to right-click on the track & chose from the menu, or use a keyshort, (depending on how I'm feeling!) if I want to unroute something.
Best wishes,
Olga. |

The original Easy-PC prototype was written to run on the BBC micro, but ported to the PC and released in 1987 IIRC. The current Easy-PC still uses much of that original look and feel and command structure, though of course it's broadened and improved to a vast extent. That really is where this issue with delete comes from, as originally there was no link between schematic and pcb (what's a netlist?) so delete really meant just that. It's been retained as a significant minority of users still prefer to create their pcbs on the fly. Some even use the reverse engineering feature afterwards!
If some of these Johnny-come-lately big programs do it a different way, then obviously they were worried about copying success... ;-> |

Oh yes.

Me too.
You have no idea how much effort it was to check the netlists of a big board (by hand, I hasten to add!) when they'd been generated by two separate programs. (This was just after EPC had gained schematic capability, but it wasn't as sophisticated as it is now, so I was still using an alternative.)
I printed out the two netlists & took them home one weekend. My husband & I played "netlist bingo" all of Sunday to check them! (Then he wrote me a program to do it instead. What a blessing that was!)
(Sorry for the ramble!)
Best wishes,
Olga. |

Aw, cool! I didn't know it was originally a Beeb app. :)

Quite!

Olga.... From the sound of it, you probably like me... did layouts BEFORE the PC was on the scene.
Remember the black tape..... or the red and blue if you were doing double sided. I often think back and wonder how we ever achieved designs and kept our sanity !!

I've been doing this for quite a while now, but thankfully not that long! I've never used the red&blue tape... I have heard about it, though, & I do wonder how sanity was maintained! I do like how it's continued on in the colouring of the layers in layout-apps now, though 
My other half used to do hobbyist-eletronics-layout & I do remeber the transfers & black permanent pen!
I came to it while Windows 3.11 was de rigueur, and EPC was a DOS app, when netlists were unheard of & you checked the PCB layout by scribbling out the connection on the circuit diagram!

| I've still got a box of the stuff, and transfers. Would anyone like it? |
