3D pdf with Rhino (Simlab)

Hi all,
I’m trying to export a 3D pdf using SimLab but the plugin doesn’t work at all. The pdf turns out empty. I already checked similar topics and I have read about SimLab and people say that SimLab works. I use now the trial version, I wanted to evaluated this plug in before go ahead with the purchase and definetly I will not do that if it doesn’t work at all bu it might be it is me doing something wrong. Do you have any tips?

Contact the SimLab developer and ask them.
