The fix is to uppercase these markers, since the tokenizer is case-sensitive. The following command will do the trick:

sed -e ‘s/e\([-+][0-9]\)/E\1/’ patched.stl

apparently with GNU sed, the following will work too:

sed -e ‘s/e[-+][0-9]/\U&/’ patched.stl

Note that I haven’t tested these commands for syntactic correctness, but they should give you the idea.

I haven’t done any work on an M3 converter yet. It’s a much more complicated format than any other 3D files I’ve worked on because it also contains bone animation data. That data would need to be parsed as well – otherwise, all the models would end up getting fabricated with their arms sticking straight out at their sides!

I’ll need to build a model viewer and rigger into 3dc in order to get sensible poses out of M3 models. Luckily, much of that can be reused for other game and movie model formats.

In short: it’s a lot of work, and it’s going slowly. But I’ll get there eventually!

Funny way I stumbled my way here.

I’m actually trying to convert the bliz activision files so i can get them into a format so i can have them printed on a 3d printer or cut down from styrofoam.

Hows the development coming along for the M3 format?

I started making a ruby dsl for auto-generating toolchains of cad format conversion utils, gcode generators and cnc drivers last summer so I could send stls, dxfs, etc. to Hacklab.to’s laser cutter and makerbot through a web page but never had enough good cnc command line utils to get it working for anything but dxfs and stls and even then half the time the utils still crap out because of formatting issues.

Anyways, tldr: Thanks for the util, it’s the gradual accumulation of small utils like this that will bring automation and manufacturing to open source.

Plus I think we have enough half-baked GUIs to go around with things like cam.py and reprap host.

Btw, lots of less glitchy drivers then RepRap Host are available at: http://reprap.org/wiki/RepRap_CAM_Toolchains#RepRap_Drivers
