BUT, then from inkscape, write a dxf to take to the cutting shop, the dxf is just useless junk.





Yeah, I wrote about that a few posts ago. Here's an excerpt:

Just to see what happened, I tried to convert the SVG to DXF using a couple of different programs - it wasn't pretty. In one case, the conversion converted the curves in the wrong direction, and in another, the clipping paths weren't honored, so the DXF ended up with lines all over the place where they didn't belong, so it took a good bit of manual editing to get it right.

The second program of which I was speaking was Inkscape.

What is the difference ???





The difference is that I'm calculating the cutouts' positions, mapping them onto a big square, and relying on a circular mask to constrain them. I'm auto-generating W3C "standard" SVG, and apparently Inkscape's DXF generation routine doesn't quite have enough information and/or smarts to do a good translation.

Adam actually drew his template in Inkscape - so it knew how to join the lines, and the order in which he did things, etc. I'm guessing that it in that case it "knows" enough to make a clean translation.

If it's useless to you - sorry. Personally, I found generating the SVG, then editing the DXF file to take out the extra lines a lot less work than trying to draw one from scratch.

At this point, I'm not sure what - if anything - I can do to rectify the situation, but I haven't given it a lot (er, any) thought/time/effort. If/when I come up with something, I'll be sure to post it here.
