Thanks for looking into it, Michael.

It will really be helpful when MoI will allow round tripping ...

In the meantime I think I can work around it but it will take a little thought about how to approach a project in a slightly different way than the rut I have worn in my brain pathways.

I started the modeling (in MoI) of a house I'm designing and then imported the model into the Rhino template I used for all the floor plan stuff (including a lot of linetypes). Then I realized that I would have to stay in Rhino if I wanted to preserve those attributes and pulled some hair I can't afford to lose.

Thanks again ... keep it in mind for later.
