Hi Michael,

I understand what you're saying. Sub-D's are fine for continuity but not so easy when integrating into the cad world. I often get requests from my client for STEP of SAT files from bottles I've built using Sub-d's and I have to either go down the T-Slines route, which makes for mega heavy patch meshes, or completely rebuild in Nurbs. This is why I'm trying to lean more towards MOI/Rhino from the start so I can have less rebuilding to do. It's all good fun really!

The modeller with splines was definitely shade. See here:

Only poly based though so no good for me either!

cheers
Roger
