I’m looking at creating a new module, with a board with a non-rectangular outline. To be truthful, the drawing tools in Eagle Light (I’m on v6.1) are awful, and I’ve already got a larger version of the shape in Inkscape (SVG, though Inkscape can export to lots of formats).
I found a script that works for importing DXF files (From Illustrator to Eagle: Vector graphics in circuits – todbot blog ), and Inkscape can convert to DXF. So I’ve managed to get the basic shape imported.
What I need to know now is what I should do to ensure that my board outline is all connected such that the board will be cut properly. I seem to recall from my first module outing that this was a problem with my original board design, and thankfully @ Architect caught that before I sent it to be fabbed. I just don’t remember how to make sure it’s right, and if not, how to fix it in Eagle.
PS - what ever happened to the ability to mark a forum post as a question?
When you are in that ulp dialog window switch to the tab that has generated script text (or press a button I don’t remember). Script text should appear, basically it will be a WIRE command with a bunch of points. Something like this:
Copy the script into a *.scr file.
Now you can run this .scr file.

Just to make sure I understand…first and last points for the entire script? Not first and last points for a given WIRE command? Or should it be the whole first line copied to the end?
I tried just copying the first coordinates to the end (just the first set in parens), and that doesn’t seem to have made any difference in the final result.
Yes, the first pair and the last pair in the WIRE command should be the same.
Did you copy the text into a new .scr file? And the run the.scr file instead of .ulp?

Yes, I did. Here’s the new last line of my .scr file:
WIRE (99.668449 194.156873);
first line is:
WIRE (99.668449 194.156873) (99.256765 194.055370) (98.891066 193.595483) (98.562433 192.852800);
Still ending up with a bunch of disconnected line segments. Not sure if that’s OK or not.
Can you please post the unmodified generated script?

Oh, I see. Looks like the original vector shape is just a bunch of segments. You have to make sure that you vector is one single closed path. I can take a look at your svg file if you want.
Actually you can merge all these WIRE command into one manually and repeat the first point at the end. Try this:

@ Architect - The merged WIRE commands seem to end up with the same result.
How did you get the 3D shape in your pic? Is there something in EAGLE I can use to validate that the outline will produce a proper board?
Perhaps it’s already OK, even though it doesn’t look great in the board editor.
I have used EagleUp script and Google SketchUp to make 3D. Before merging WIRE commands it would not create 3D model.
I would still cleanup original SVG/DXF - you have duplicated segments.
Thanks!
The SVG is just one path node, so I’m guessing that the duplication must be taking place either in the conversion to DXF, or in the import from DXF to Eagle.
Looking more closely at result of the single WIRE command version import, it’s apparent that this version is indeed a closed path (or perhaps multiple paths, as you note).
I’ll look at the files and see if I can figure out where it’s going wrong. At least it appears that this version has a good chance of being fabbed correctly.
I suspect that you have more than one layer in your SVG and the DXF export function exports all layers.
@ Architect - I think I’ve got the .scr file cleaned up. Looks like for some reason, the DXF importer was generating two full paths, perhaps because of the thickness of the stroke in SVG. Either way, I found the start point of the second path, removed everything between it and the duplicated starting point, and re-ran the script, and it seems to give me a solid path.
Thanks again for your help!
Forgot to post my Sketchup pics of the board…
and, as it happens, the manufactured boards arrived today from DFRobot.
Sadly, the bottom silk screen is missing, but otherwise the boards are perfect!
EDIT: Oh, and of course I should post a pic of the finished module.

Looks great!
Thanks.
Took a bit to get one hand-soldered…that’s a lot of pads on the LEDs, and the footprint of the pads is a little smaller than optimal for hand soldering. The caps on the back were easier, though still a bit fiddly by hand. The socket was a breeze thanks to your large-pad part for Eagle.
Thanks again for all the help. Now I just need to figure out what gear I need to do some hot-air reflow…not planning to do any more of these by hand, if I can help it.
