kaom, Here's what presmooth can do Normally AGr deforms the mesh in the direction of it's normal, which for a cube is straight out from the face. Presmooth smooths the normals before doing the deformation so that the normal points straight out from the edges, tilted 45 degrees from where it was. This helps keep the edges together, but does skew the deformation towards the edges a bit. Adaptive mesh just looks for places where it can use a few big facets instead of lots of little facets. Less facets = less memory, faster renders, and a more responsive Carrara. Eric Winemiller Digital Carvers Guild Freeware and commercial 3D extensions http://digitalcarversguild.com
