Setting the, the object can be linked to the deformation of bones. And you can edit the generated object in more detail by modeling capabilities. This feature will reduce the time to create the object. You can create an object by specifying only the center line and the line width. With, you can create an object shape along the center line. And you can easily add edges (divide a face) or erase edges (merge faces). You can make a polygon with 5 or more points. Bevel - creating a fillet surface (a rounded corner) is added.Bridge - It creates a pipe-shaped polygon in between holes.Fill up a hole - It automatically fills in the holes on the surface.The following features have been added and improved, in ver.4.0 or later. And it also has functions to assist in the finer processing. Metasequoia has basic polygon editing functions. Metasequoia is a user friendly, easy-to-use 3D-modeling application supporting numerous popular file formats.
