It’s always the funky ones…

Funky glasses

Funky glasses

I bought several1 pairs of glasses online recently.  They’re so cheap2 that when I order them online I make a point of getting one pair that looks like the pair I’m currently wearing, one pair that is kinda funky, and two or three pairs of glasses that are somewhere between what I’m wearing at the time and funky.

The funniest part is that I invariably3 enjoy wearing the funky pair the most.  Out of a $40 order, I’m overjoyed if I get one pair that I really like.  In any case, the above is the funky pair with the other four being considerably more conservative.  I’ve only been wearing this funky pair for a few hours now, but I’m pretty sure they’ll be my favorite.

  2. $37, shipped, for all five pairs of prescription glasses with frames, cases, cleaning cloths, extra nose nubby bits [↩]
  3. Well, twice now [↩]

I’m so giddy!

I can’t wait for OpenSCAD to finish rendering this new object I’ve fashioned out of a DXF file!

Toolpath was basically:

  • Inkscape importing PNG image
  • Convert image to SVG, reduce colors, simplify lines
  • Export to DXF
  • Incorporate extruded DXF into design

It will be mine.  Oh, yes, it will be mine. 12

  2. That’s a red herring.  It’s clearly a Doctor Who themed object. [↩]

What’s the best toolpath for SVG to OpenSCAD?

While I have one selfish motive for wanting a reliable toolpath for going from an SVG to OpenSCAD, I’d also like to do a tutorial on this. 1 2.

  • I can export an SVG from Inkscape to a DXF.
  • I can import that same DXF into OpenSCAD.
  • I can’t render the DXF or extrude it into a solid.

I just can’t seem to make OpenSCAD make heads or tails of that DXF.  Is this a problem with the DXF files produced by Inkscape?  A little bit of Googling tells me that Inkscape v0.48 (the one I’m using) exports in DXF R13 format which includes features that are not well supported by OpenSCAD.  My attempts at finding plugins that will successfully allow Inkscape to expert to DXF R12 format have not been fruitful.

  1. 3D Models with OpenSCAD on Make uses a toolpath that isn’t available in my version of Inkscape
  2. DXF R12 exporter, didn’t work for me
  3. DXF R12 exporter, didn’t work for me either
  4. Yet another DXF R12 exporter that did not work for me
  5. Link suggesting that something called “pstoedit” might be helpful in converting SVG’s to DXF R12’s.
  6. From Photo to Inkscape to DXF to OpenSCAD to MakerBot to Costume Jewelry is an excellent tutorial on the exact toolpath I would like to get working

After MUCH fiddling around I have discovered that the only DXF exporting plugin I can get to work is the one called “Better DXF Output”, NOT to be confused with “Better Better DXF Output.”  Unfortunately, I’ve installed so many of these little plugins I no longer recall exactly which combination of them might actually be working for me.  I’ll do a little investigation and post a short tutorial on how it’s worked for me.

Edit: I’m 85% certain this is the plugin that worked for me.  http://www.bobcookdev.com/inkscape/inkscape-dxf.html

  1. Selfish as in I already have an idea for how I would use this knowledge to make something cool. [↩]
  2. What could it be?  Hint:  It’s related to something that rhymes with “Doctor Who” [↩]

On April 14 I posted that ProfileMaker had served up 209 profiles to 58 people.  As of right now there’s 598 profiles and 144 people served.  That’s a lot of repeat business! 1  The number of people increased by 100%, the number of uses went up by 200%, and the amount of my awesome went up by 37%. 2

I figure this means either:

  • People really like it and are using it a lot
  • People really hate it and they are clicking the same button over and over again cursing my name

I hope it is the first one.

  1. And, by business I mean people clicking a button on a free web service [↩]
  2. I’m rounding here [↩]
