Hi, I am the man you are looking for
But ; I also have a cad project that can run on Windows and Android systems I'm working on. The file is very fast and stable in terms of reading, viewing and printing, but object creation is not yet at a sufficient level, I am developing it as appropriate. Currently, the Android leg is fantastically developed.
First of all, it can read in Rsn (Binary format), Dxf, Kml, Hgt and Xyz formats that I created and write in Rsn format.
Polygon and line objects on the project can be exported to Google Earth.
I have knowledge and experience in 2D rendering of drawing objects.
