Converting OpenRocket files to Openscad

[bdureau]

It has been a while since I touched any OpenRocket code ... However this afternoon I got fed up converting OpenRocket components from PDF which is really difficult when you have large parts.
In order to make my life easier I have been writing a simple Java program that extract all rockets components from an OpenRocket file and generates the OpenScad code for each components so that I can cut them with my CNC. Could also work for Rocksim with a few changes.
so far supported component are:
bulkhead
freeformfinset
trapezoidfinset
centeringring
ellipticalfinset

The plan is then to convert them to SVG

I could do also tubes or noise cones so that they can be converted to stl
If people are interested I will release the code in the next few days when I have made it user friendly.

I just put the code on my github directory

Wow, thanks for doing this and posting! I'll take a look.

Interesting!

Really cool! Does it auto include clearance for the centering rings and bulkheads?

no not yet

Just follow the link and download the jar as well as some example conversions

Just had a play with my home made CNC

From the OpenRocket design


To the cut

Those are epoxy fins, I put a mug for scale

I like your project. I've never worked with OpenSCAD, but made a similar (freeform fins only) interpreter to go from OpenRocket to DXF, which is compatible with a lot of other CAD packages. At the end of the day, I lost interest, but it looks like you've stuck with it and have something cool and have shared it.

Good work!!!
