patent drawings

Emanuele
Hi everybody,
is there a way to create patent-like drawings with openSCAD?
Or is there a (free maybe) software I can export to and then render it?

For who doesn't know a patent drawing must be in b/w (no grey scale), shadow can be rendered with parallel  lines, and if there are sections, they have to be filled with 45° tilted parallel lines (in each section the lines must have a different gap)

Many thanks,
Emanuele

I would see this as an STL-Rendering task, and as such not per se part of OpenSCAD.

Of course, OpenSCAD could well be imagined in a Workflow for patent drawings, but I'd imagine modelling and exporting to STL in OpenSCAD and then rendering in "patent-style" from STL by a different tool/renderer in the toolchain.

As far as I know, there is no way to do so using OpenSCAD exclusively.

As a patent professional, I can tell you that any piece of crap drawing is acceptable to the USPTO, until the Examiner tells you it is not. If you have not yet filed, just print out whatever you've got, and see if it will fly, you can correct them later. A good test would be to print out the drawings, photocopy them, and the photocopy that, and then photocopy the result - if it is still legible, the examiner is unlikely to object to the drawings. If you really wanted to ensure that the drawings are black and white, I would export a 3D drawing to GIMP and then play with the contrast and brightness, until you have a result that would pass the above test.

After searching the internet it's true, there is a need for an open-source way to convert a 3D object into a patent drawing (which complies with the following rules: http://www.law.cornell.edu/cfr/text/37/1.84).

In the User Manual:

http://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Libraries

this library can be found:

http://www.cannymachines.com/entries/9/openscad_dimensioned_drawings

but this is more for technical drawings and it seems to be difficult to
get it to do compliant drawings.

FreeCAD (http://freecadweb.org/) has some tools that are more geared
towards drawings, and can import OpenSCAD models. But I do not think
support for textures is very good.

I guess the most promising candidate is Inkscape (http://inkscape.org/),
which is very powerful and allows to fill with patterns. One can export
sections of a model to dxf from OpenSCAD and import that into Inkscape.

Greetings

Re: patent drawings

Thanks to everyone who answered.

At the moment I think the best solutions are:
but it's a beta version, or to use Inkscape.

for the texture in the sections I think it would be feasible to create a module like this:

the shadows are more difficult to render, but they are not mandatory for a patent drawing.

Thanks,
Emanuele
