Do you know a tool/application that allows me to draw a directed graph (with drag and drop would be ideally) and than easily export it into an XML or JSON file?
I tried using http://cmap.ihmc.us/ but it exports the picture into an XML not the graph's content, which it makes it horrible to parse.
The main goal is to draw a graph and then somehow construct it in memory (in C++/Java).
Gephi is a good free tool to create and export graphs:

User made addons are available and allow you to export in multiple formats :

Is there a way to export WA conversations (automatically exporting to .json file) and have converted to a Visio, or similar, type diagram showing actual flows?
You can export a dialog skill / workspace either through the browser UI or the API. Another option is through 3rd party tools like my conversation tool.
I don't know of any conversion tool from the dialog nodes in the JSON files to something like Visio. There are cross links from the individual dialog nodes to parents and children which you would need to analyze.
I created a blender project, exported it as JSON+BIN files and showed it through the blend4web webplayer. Everything goes fine until my need to change the JSON file programmatically to add/remove a new 3D object (e.g. a cube or rectangle). I want to renderize the already showed 3D model adding or removing a 3D object. However, since the exportation of a project to blend4web generate a .bin file, if I change only the .json the model was not showed as expected. Considering this scenario, the unique way to change the model is modifing the .blend file and exports it again from Blender. But based on my need, I can't add a new 3D object in a Blender project programmatically considering the .json file. Additionally, the .json file which I am updating/using is considering data retrieved from a Database, such data indicates how and the position where the new 3D object will be displayed in the scene, which hinder me to use Blender to create a 3D Model modificated.
In this perspective, I need help to identify:
Which is the best way to change the scene and show it in blend4web programmatically and mainly considering a .json as an input for the model?
Is there any python script to user a blend4web .json file as an input to be compiled, without the Blender project and regenerate the .bin file, making it possible to show correctly my 3D model using the blend4web webplayer for JSON files?
Or, is there some (easy) way to modify a project from Blender considering data in JSON format, compile and generate the files to be shown programmatically by the blend4web webplayer (for JSON)?
Thanks in advance.
I would like to build a CNC manufacturability analysis app using Autodesk Forge.
Setting the computational geometry algorithms aside, what kind of geometrical data can I extract from CAD files using this platform? also, is there an existing app I am unaware of?
Thanks
Depending on the input file format you can convert to different other formats:
Supported Translations
Though it's not obvious from the above list, all input formats support conversion to OBJ format, which can also be done at subcomponent level - so you don't have to export the whole model to OBJ.
Here is a sample that lets you access your files from A360 and convert them into whatever format is currently supported for them:
Model Derivative API sample

This is the options panel for FBX export in Blender. I have no animations, just an UV unwrapped object ready for export. What checkboxes should be checked to correctly export objects for libGDX use to FBX file format.
If you're not exporting all the objects in your Scene, checking "Selected objects" will only export those that you have selected.
For certain shaders, "Tangent Space" is also needed for UV exporting, if your materials look okay after import without tangent space included, you probably don't need it. But, it does increase file size.
If the mesh is not skinned, you can uncheck "Add leaf Bones".
You'll get a better idea of everything that is exported if you convert your fbx to .g3dj rather than .g3db. .g3dj is a JSON file, which you can open in a text editor and check everything out, and/or edit if need be. Play around with the settings in the exporter, convert, and see what you get!
First of all: I'm a skilled developer and a total noob of 3D solid files/drawing.
I started playing with webgl and three.js. My task is to port a solid 3D file(i.e. STEP/IGES) to a web page(a sort of a cad viewer).
I started from this example:
http://www.johannes-raida.de/jnetcad/RadialEngine.htm
I want to obtain something like the above link with
a navigation tree and hide/show layers functionality.
The above link has sever json file, one for layer.
I want to obtain: a threejs-json file for each layer to get the hide/show functionality.
Now, I have a solid file (STEP format: .STP). That file contains layers. I want to obtain a json(three.js) file for each layer.
Questions are:
how to export to threejs-json using free software? I read that the best method could be: STEP > Wavefront OBJ [using freecad?] > treejs-json [using blender?]
Does the collada format is better than obj?
Shoud I have to manually export each single layer to json?
Is there an utility out there to generate all the layers(separated files)(json-threejs format) from a 3d file?
So, I did it by myself.
Three.js is a great library but it requires some 3d skills.
Here are my answers:
how to export to threejs-json using free software?
Well, my suggestion is to convert your solid file to DAE, use anything you want.
Then open DAE with Blender and use the exporter script of three.js:
https://github.com/mrdoob/three.js/tree/master/utils/exporters/blender
Shoud I have to manually export each single layer to json?
No, the 3D file has all the informations about layers. So you can use a single file.
Is there an utility out there to generate all the layers?
I don't have found somethig good out there.
If you want to create single layers, you can split the json file created with blender.
