Hi, Currently we're -an architectural office- are using Rhino for a lot of our modelling. Though its time to sober up & start using a parametric modeller. What's really cool about Rhino is how easy it is to script it, and how in depth its methods are made available to you. Currently I'm writing modules for Rhino from Python (JungleBoogie!) via COM which is working very well. The only thing that troubles me severly is that Rhino just isnt a parametric modeller. Which does make it a bit of a stone-age modeller. Could you share some of your experiences scripting Solidworks with me? I haven't found a single thing on the solidworks site on scripting it, which does worry me ;) Cheers, Jelle
