Re: gEDA-user: gschem add net problem
This sounds familiar to me. I think I've seen this before and had to add 1-unit segments going down to connect all the parts to the horizontal net line. --- On Fri, 6/24/11, Phil Taylor p...@plastitar.com wrote: From: Phil Taylor p...@plastitar.com Subject: Re: gEDA-user: gschem add net problem To: gEDA user mailing list geda-user@moria.seul.org Date: Friday, June 24, 2011, 10:50 PM I usually draw net stubs coming off any long net for the visual safety of seeing each one fully drawn.

gEDA-user: gschem add net problem
When I create a schematic, if I try to put more than one symbol on a net, it does not take. For example, if I were to put three resistors vertically, right next to each other, then add a net across all three on top, and another across all three on bottom, gschem indicates by adding a dot, that the middle resistor has been connected to the net. But if I try moving the middle resistor, it does not rubberband like the two outside ones. This happens whenever I try to install a symbol on a net. I can get it to work by moving the part off the line and connecting another net to it manually. But as soon as I try to move it back into position, the connection goes away, and it will not rubberband. Right now I have it working by having components that are supposed to be in a straight line (for appearance purposes) set up or down a bit. It works, but looks really bad. I must be missing something simple. Can anyone tell me what it is? Thanks, Tim ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: gschem add net problem
Thank you for your response. So how would I include the center resistor in the net as described in the example below, other than moving the resistors around in a irregular pattern and creating separate nets? I've tried creating separate net segments, but as soon as I add the next segment, the middle part drops out of the net. Somehow I'm missing the trick on how to do this, or missing something very basic.

Re: gEDA-user: gschem add net problem
OK, I think I finally see it. In the example below, I would need to place a net from the pin of the middle resistor to the net connecting the outer two resistors. I can't just drop the pin of a part on an existing net.
