[daiduongbit]

Hi all, i'm beginer with the jPCT. I have a problem when export from 3D object to the autoCAD format (dxf).
But i'm not sure can be that. Please suggest to me some way do it! some example do that thanks all!

I'm not sure what your actual question is. How to import a file in dxf format into jPCT-AE? Well, unless your are writing your own importer for it. By default, you can use OBJ and 3DS. Just convert your file into one of these formats. If that wasn't your question, then what was it...?

That was not actual my question. I want to ask after import multiple object 3D to android app(example: show it...) then i want export all to a object with dxf format? So, can i do that? Thanks so much!

You want to export the data from the app into dxf format? That's not supported by default. You can use the PolygonManager to access the mesh's data and write your own dxf exporter... There should be an example somewhere in the forum that does something like that for ASC format. But why do you actually want to do that?

  Yep, that's is exactly i want. I want to do that, purpose my app is  join many 3D objects in a layout to an object then export to DXF format can be import it to the AutoCAD tool but I'm not sure  3D object format and dxf file format to convert them. That's very hard for me, could you suggest to me any library do that. Thanks you and sorry my english not well

No idea about some library that might help here. In general, something like jPCT is more about importing and rendering stuff than it is about exporting data. It provides the basic means to do it, but have to write the exporter yourself or, if you find some lib that writes dxf, you have to write the glue logic between both.
