When I export a file from SW to a 3D PDF the dimensions seem to be slightly changing. I exported with maximum accuracy. One of the dimensions as you can see in the attached image went from 1.500 to 1.503. SW 2017.
I am also having other issues where the templates are not showing correctly when the PDF is generated, not sure if this is an Adobe issue or what. I updated Adobe with no luck. The 3D PDF stuff seems to be a little sketchy thus far..
