    Hi Jason,

     

    take a look at www.cadsoft.de/download.htm, ULP directory. ==> statistic-copper-plane.zip

    This might help.

     

    Suggestions should be posted in the CadSoft newsgroups directly. They can be accessed via news://news.cadsoft.de.

    As far as I am informed these groups will become accessible via element-14 soon.

    Thanks for that, I'll take a look at it later (when I'm back home. I'm not sure if it's only the statistics for the polygon, or if it includes the traces, pads and via as well - will experiment).

     

    I've been putting off installing an NNTP client on my machine image That might be the impetus I need to do so.

    Just another ULP comes into my mind. Try statistic-brd.ulp that comes with the EAGLE installation.

    Now I've been able to have a go at them, the first one worked more as I would've liked it than the second (which only seemed to produce a rough statistic as to how many there are - the one that looked the most promising was the area consumed by the devices on the board).

     

    The first one does appear to give me a surface area of how much would've been etched away *, and it does have some oddities when a trace goes over a via/pad - most of the time it appears to draw the trace to the centre of the via, but occasionally it'll draw the via with a hole in it. I haven't worked out what it does when though. This is by looking at the bitmaps it generates.

     

    It's also a little slow - but I can understand that (interpreting binary files in the ULP language is going to be slow).


    * Looking at the bitmaps, the "plane (Cu)" column appears to be related to the black area, rather than the white area - certainly bitmap ~~~0 has a lot of black, and gives 2092.07mm^2, and bitmap ~~~1 has not much black and gives 22.63mm^2 (there's a big grounding polygon over the area).

     

    I'm guessing the algorithm is effectively converting it to a bitmap at 0.1mm per pixel and then counting the number of black pixels.

     

    So, many thanks for that - although it's a bit too slow for interactive use, so I'll use it as a bit of experimentation so I can get a better idea based on visuals.
