My relationship with EIM is a bit strange: after so much time not digging it at all, suddenly I started to understand it just when it became end-of-line’d. NURBS are not that much fun to me yet (actually, I am pathetically attached to beziers’ ease of use, even if they mean potential trouble for further modeling of an object. I am trying to drop them), plus EIM is a bit intolerant and spartan in places. My hope is Tesla does it better.
My old copy of EIM is rather unstable on my Mac Pro, so I am not doing much with it nowadays.
(I started playing with Hexagon some months ago, and I think I am beginning to get results with SDSs. The thing is, Hexagon, being of Amapi’s lineage, does certain things different than other SDS players (it has NURBS-like surfacing tools, construction history, etc.), and IMHO, it is more handy a tool than Modo or Silo in certain ways. I’d like Tesla to adopt its style of SDS cage tools, as I don’t like EIM’s ones too much.)
