MESH command
The MESH command is used to create 3D mesh metafile objects, such as box, cone, cylinder, sphere, wedge and torus.
Command Access:
Menu : Draw > Model > Meshes> Primitive
Command : MESH
Command Prompts:
Enter an option [Box/Cone/Cylinder/Pyrmaid/Sphere/Wedge/Torus/SEttings]:
Function Description:
The basic mesh style (mesh metafile) is equivalent to the 3D solid metafile. Users could remodel mesh objects by smoothing, sharpening, optimizing and splitting, as well dragging edges, faces and vertexes.
Note: by default, the smoothness of new created mesh is 0. Users could change the default smoothness by specifying the "Setting" option under MESH command after specifying mesh type.
