I seem to have a similar issue that was address here: Imported background textures 1 but I still can't figure it out.
My model is extremely sensitive to distances, which I have drawn in Google Earth Pro using Paths. They are outputted in a KMZ file with Lat Long info.
How can I get these paths in scale inputted into my model? I will need to build on top of it, so a background may be best. And when I update the Google Earth file, I will need to input the revisions into FlexSim and make adjustments accordingly.
