You have to ask where your models will be used the most. If you're targeting archviz, or gamedev audience, then engineering software is not the best choice to create the models, because those people needs polygonal models with good topology and clean UVs and AFAIK CAD programs are not very good at this. Your models are published with almost zero relevant information for aforementioned audience. If i would be a buyer, i wouldn't give second look to your models. Think about that.
