Well, I learned a little more today ...

If I set the linetype in Rhino by object and then copy and paste it into MoI and then copy and paste back to Rhino the linetype is gone ... reverting back to the default of continuous.

But if I make sure to give the object in Rhino the layer designated as dashed linetype then I can copy and paste it back and forth and keep the linetype properties.

Good stuff and thanks again, Michael.

Just takes a little practice and getting used to.

cheers,
eric
