in the old version you could include your track via a trax_viewer into your own website. There was a link which could be included into your website source code.
Does this feature still exists in the 2.0 version?
Another question about the possibility to save the trax into a .trx file. how can i use that file?
It would be great if the mentioned trax_viewer is still available and you could use your downloaded .trx file and load that file with the trax_viewer.
The TRX file is currently not very usable, it was put in for future use by other model railroad design tools and control systems. There are a few manufacturers currently working on a product that can read this format.
I'll need to fix the option that gives you the link.
