Exploit SketchUp file from/for Java application

[Xavier NOPRE]

Hi,

I know it's not the really good forum, but I need your help, I don't know where I can post my question ...

I'm developping a Java application, and I need to read SketchUp files to extract some data like volumes, areas, etc ...

How can I do ? Can I read SketchUp file from Java application ? Can I launch a script (Ruby script ?) that can read and exploit the SketchUp file ? Other idea ?

Thank you for your help !

Xavier

The SketchUcation Developer forum is a very good resource.

There are basically two ways to approach this:

* Write a Ruby plugin that exports the desired data in some
desired format (eg, JSON, XML, YAML). This is an easy path,
but (by default) it requires you to run SketchUp (and the
plugin) interactively. SketchUp _can_ be run in batch mode,
but that adds another layer of complexity.

* Use the provided SDK libraries to read SketchUp files from a
C++ application. This can get a bit complicated, but it is
almost guaranteed to have better performance.

Hi Rich,

Thank you for your answer !!!

This 2 solutions can be good for me. The solution with Ruby plugin should be a good way to learn Ruby ;-), but I have some other questions :

• The SDK is announced for Windows or Mac : is there a solution for Linux ?
• With this SDK, is it possible to extract areas and volume (for a house) ? Or do I have to calculate it myself ? In this case, can I Found some examples ?
• For the "Ruby script solution", for example, can I run Sketchup in batch mode, working on a specified SketchUp file, and activating my plugin ?
• Same question as above for areas and volume : is it possible with Ruby API or do I have to do it myself ? 
• Where can I find some examples ?

Thanks a lot for your help,

Xavier

I don't know for sure (I have no actual experience with the
SDK), but my suspicion is that a C++ library should be usable
on any OS. My suggestion is to download it and take a look.

The Ruby API can calculate areas of individual faces, but I
don't believe this information is stored in the model. Any
higher-level aggregation (eg, volume for a house) would have
to be calculated, based on domain knowledge (eg, architecture).

Yes, but it's a bit tricky. This page may be helpful:

You might look around on the assorted plugin archives, eg:

ScriptSpot

Is it possible to use this SDK in a Java or c# application or just in C++ application ? or is it possible to use a C++ application that will get the information from a sketchup model (area ... ) and use it in a java application ?

There should be an omni platform that allows access to the objects/ key data variable (Data dictionary). So please copy me on this also

tnx in advance
