I proposed my alignment in Google Earth at preliminary stage, saved in KMZ format.
How can i use this File in PRT to prepare my Detailed Alignment further?
Is there any additional tool require to convert in dwg format or i can use directly in PRT.
Suggest me best possible way to use KMZ files in PRT.
We can't use KMZ in PRT. A workaround is to use SketchUp as an intermediate step.
Another method is to sketch directly in Rail Track after having imported google view (maybe many to get enough details) or use BingMap as a background map in Rail Track (SS4). To enable BingMap raster attachement, you must add a variable name MS_RASTER_BINGMAP_KEY and set it equal to your BingMap key.
