Dear, everyone Does somebody know that how can i do the mesh using two different type shapes? That is to say, as for the volume which has two parts. i want to mesh the top part using triangle and the bottom part is rectangle ? how can i do it? i just can mesh using only one shape mesh//// thank you for your help. cheers On 2 Aug 2012, at 12:02, Serban Georgescu wrote:
