An editable mesh is a type of deformable object. An editable mesh is a trimesh: that is, it uses triangular polygons. Editable meshes are useful for creating simple, low-polygonal objects or control meshes for MeshSmooth and HSDS modelling. You can convert a NURBS or patch surface to an editable mesh. Editable meshes require little memory, and are a natural method of modeling with polygonal objects.
An actively linked object cannot be collapsed to an editable mesh. Using the File Link Manager, you have to Bind the object first.
