+5V copper pour not working.

phoenix710

First, thanks very much for a great package. I learned CAD tools in the

late 80s/early 90s (Omation and Tango). Your tool is a considerable value.

 

I've completed my first board, but have a single issue that I haven't been

able to resolve from this forum or googling generally: what is the

procedure to produce a power plane?

 

I have successfully used the POLYGON for the GND net; it works as expected

and connects GND pads to the plane with a thermal. The GND plane is the

bottom of a 2-layer board.

 

The issue is that I haven't been able to do the same thing for my +5V net

(which I want for the top layer). Using the same procedure as for the GND

POLYGON, I get the following error when attempting to name the POLYGON:

 

Invalid wire width: '+5V'

(valid range 0..7874.01575 mil)

 

The wire width is set at 30 mils, which should easily be in range. (And,

this is the value that I used successfully for the GND POLYGON.)

 

What have I overlooked? I'm assuming that a POLYGON can be named to any

net, so I expect that that is not the problem, but I'm stymied on what the

issue is.

 

Thanks.

Dave

    That got the pads connected to the power plane. There is now another issue

    in that the right 1/3 of the board is isolated. (That is, the pour didn't

    fill a third of the board.) Hopefully, I can find a clear path in order to

    guarantee that the +5V net fills the (now) empty section.

     

    Check the "orphans" property of the polygon.  It's not filling because

    there is no path that is filled to get to that area.  If you turn

    orphans on, this area will fill, but will leave an air wire between a

    node that is filled and one that is not.

     

    Enjoy,

    Chuck:

     

    Selecting the polygon is a bit clumsy, but I was finally able to

    right-click, then pull up the context menu that contains the NAME command.

    (Using the NAME command in the command line didn't work, or at least I

    couldn't find a combination that worked.)

    Thanks much, your hunch appears to have answered the original question.

    Just off hand, it looks like the "change width" command was still

    active.  Try typing "name" in the command line, then click the polygon

    outline.
