Who is the maintainer?
February 16, 2010 12:01PM
Simple question: Who is the maintainer of the RepRap designs?
I have asked pretty much everywhere about where to send all the
improved and repaired parts so they get back into the trunk-version...
I asked who I needed to contact to get SVN access....
Noone ever answered me yet.

Is this supposed to be some kind of "development by secret society"?


I wandered around [objects.reprap.org]
to find out WHO maintains the designs and steers the project.
Nothing!
It just says that there is a version "Darwing" and that there is a
version "Mendel" and where to get the design. Not a single word on
collaboration, milestones, history, progress and most of all PEOPLE.


[evelopment" target="_blank" rel="nofollow">objects.reprap.org]
tries to catalog all these patches, improvements and upgraded prople make.
INSTEAD of getting them into the trunk version to call them Mendel 1.1
and 1.2 when the maintainer says they are ready.

Adrian Bowyer steers the project. Ask him for SVN access.

The rest of the secret society are here: [reprap.org]

The problem I have found with the parts is that the STLs are generated from AOIs, which are considered to be the masters. If I check in a fixed STL then it no longer matches the source. I cannot fix the AOIs because I always get array bound errors.

I have read that site.
Lots of random names and background but it had no roles.
I added a table to fill in the page at objects.reprap.org that
was supposed to replace it.

You get ArrayIndexOutOfBoundsExceptions when orienting parts properly or pulling some vertexes in the mesh-editor?
What are the steps to reproduce the issue?
What is the exact stack trace and Version of AOI?
Did you already enter a bug report with AOI I could refer to when trying to fix it?

I get array out of bounds when I load some of the Reprap models. If I try to make my own I always end up with one after a few boolean ops. I can get them just by moving objects sometimes. I never use the mesh editor. "Fix all" on a non-manifold object always results in out of bounds, never actually fixes it.

If I right click on the project tree I get a null pointer exception.

Forrest and I tried a test on exactly the same model. Both with same version of AOI and XP, both same version of Java. It worked for him but not me. Since then I have changed PCs and reinstalled everything but still does not work for me.

I made a simple test case of boolean ops not working more than a year ago and posted a bug report. It got closed as fixed but isn't so I reopened it. [sourceforge.net]

Basically I find it completely useless for modelling. I only use it to orient parts for printing.

I just got one entering text in a properties box.

I would file more bugs but they never get fixed so no point really. It isn't suitable for CAD modelling anyway, even if it did work.

Sounds like way too many errors to fix and no point
in fixing them at all.

I really wonder why they use that crappy software for their masters anymore.
Even blender (with it´s broken booleans) seems to be way better.

Blender is a mesh editor, not a solid modeller, so is the wrong tool for CAD. Also nearly everything it makes is non-manifold.

As soon as you convert from solids to a mesh you have lost information so you might as well treat the STL files as the masters rather than move to Blender.

I wasn´t suggesting blender.

I think it is even worse than that: My understanding is that the originals are created in SolidEdge (not to be confused with SolidWorks) and then imported into AoI so that they can be manipulated with something available for free on multiple platforms.

The RepRap project is "Open Source" in the sense that all of the hardware designs and software sources are published. That does not make it easy for anyone outside the "Development Team" to submit bug fixes and improvements.

I don't think AOI can import SolidEdge. I think the AOI files have been remodelled by Adrian to match the SolidEdge files designed by eD. Some are a bit simpler.

No I agree there are two problems to submitting fixes. One is permission to SF, unless you are in the core team. I am in it but I can't edit the AOI files because AOI does not work.

GIT or Thingiverse solves the first problem, or create a wii page like this: [reprap.org]

I don't know the answer to second one. I think we have to treat STL as the master source files as it is the lowest common denominator, like all public standards.

working on that table Marcus made - I hadn't realized this problem but it's a good point - I'm filling in what I know.

I think openscad would be a good candidate for an object format, its incredibly quick to make objects, and parametric modelling is very powerful. Thoughts?

It´s supposed to be good for mathematical objects
but less so for engeneering.

What parametric formats can it export and import?
