Routing board manually, trace will only start at inrouted point. [message #169294] Tue, 07 February 2017 15:07 Go to next message

While routing a board, the unrouted (wire unrouted) connections are shown with thin lines.
In the beginning of the board these lines are logical and it helps routing the board. But I can only start a new trace at the point where these thin lines start.
[can not start routing at the end of the trace]
At this example I want to start routing at the end of the GND trace. But the router will not allow me to do that. The workaround is to delete the trace to the point of the unroute and then continue from there. In this case that is not much extra work. But sometimes I have to delete quite a lot until I can continue.
There must be a setting somewhere to disable this 'feature' and let me route from any point I want. But how?
I use Eagle 7.7 Premium.

Hi, I usually do the same and delete a part of the net and start routing again there but when it cames to gnd, normally I use the polygon tool to do a gnd plane to save me time instead of trace all the grounds. Also its quicker to etching the pcb and keep your circuit more immune to interference.

But it can not be true that this is the only way to route a trace! I used other routing software ,Mentor Graphics Pads, and never had this kind of problem. There you had the same lines. But when clicking on a net the line would jump to that place on the net and routing would start from that point.
Eagle has the great advantage of the ULP language and the use of eagle in the Open Source community.

This is simply not true, as reading the help for ROUTE would have revealed. If you hold down CTRL when left clicking on a location to start routing, it starts from there, not the nearest airwire end.

Again, this is all described in the help right where you'd expect to find it. Some times it can be difficult to find things in the Eagle help when you don't know enough to know what to ask, but in this case it is very clearly documented. In fact it's the first option show for the ROUTE command. READ THE MANUAL already!

Yes I did and when I do that I get a menu:
[Screen Shot 2017-02-07 at 19.32.41.png]
This software is probably not made for use on a mac with ony a toutch pad. I am planning to get a wired mouse somewhere to test if it works properly with that.
For this picture I deleted a peice of trace on my completed board and tried to route from where the menu touches the trace.

In this case it's not actually an issue with the touchpad, it's a case of the help file not covering the Mac version explicitly at every point in the manual. However in the "Keyboard and Mouse" section of the help it states that on a Mac you use Cmd instead of Ctrl. I use EAGLE on a Mac and this does work fine. The only thing that was problematic on a Mac was changing layer in v7 and earlier as it doesn't support the middle button. This issue has been resolved in v8 with the addition of being able to use Space to change layer.

Best Regards,

Rachael

To be fair, on the Mac the help is not correct when you go directly to the HELP ROUTE page as it's Cmd+Left Click on macOS. However, it's a fairly fundamental thing that the Mac version uses Cmd rather than Ctrl and it is given as a global difference early on in the help in the Keyboard and Mouse section so I am surprised this was the first thing that didn't work correctly.

Oh, and the little nugget of information that the OP was using a Mac didn't come until the last post.... It's always a good idea to give the OS version as well as the EAGLE version when trying to get help....
