Hmm......... Maybe the next patch for Carrara will address this. Or you could just buy Rhino and end all these troubles.LOL You were right rockjockjared, I love to pitch Rhino for the modeler that it is, I truly love it.********* Are you using primatives to do your booleans? Or are you using spline objects, and what are setting the quality to? I wish I had a simple answer for you. You know who might have the answer you need? MarkBremmer, that guy is a genius with a Carrara, and litst might know something we don't about this. hang in there, I'm sure someone will have an answer better than anything I can come up with. Or again just get Rhino, I'm kidding, no maybe I'm not.heh And your right, at least Carrara doesn't crash on these anymore, isn't that a nice feature. Let's give eovia a big roung of applause, for trying to sve our friend Carrara, there will be a solution, don't give up! Hey rockjockjared, when do we get to see that Ford your working on? I need some inspiration, I can't wait to see it. kaom
