A polysurface consists of two or more surfaces that are joined together. A polysurface that encloses a volume of space defines a solid.
Solids are created anytime a surface or polysurface is completely closed.
Some Rhino commands create polysurface solids. Pyramid, Cone, and TruncatedCone are examples of commands that create polysurface solids.
The Box, Cylinder, Tube, ExtrudeCrv, and ExtrudeSrf commands can create polysurface or extrusion objects. Polysurfaces can be closed with a planar cap or open.
附註
| ● | In models containing large numbers of polysurfaces, performance can be sluggish due to the relatively high demand on resources. If the same objects are made in Rhino as lightweight extrusion objects, these models are more responsive and more memory is available. |
| ● | The UseExtrusions command controls the use of lightweight extrusion objects. To make commands that normally create extrusions create traditional polysurfaces, select the Polysurface option. |
