封閉的單一曲面或多重曲面都可以稱為實體，Rhino 可以建立單一曲面實體、多重曲面實體與擠出物件實體。
A single surface can wrap around and join itself. Example commands include Sphere, Torus, and Ellipsoid. Control points can be displayed on single-surface solids and moved to change the surface.
建立一個橢圓體。
建立一個球體。
建立一個環狀體 (類似甜甜圈的形狀)。
Some Rhino commands create polysurface solids. A polysurface consists of two or more surfaces that are joined together. A polysurface that encloses a volume of space defines a solid. Pyramid, Cone, and TCone are examples of commands that create polysurface solids.
The SolidPtOn command turns on grip points for polysurfaces, which act like control points.
建立一個立方體。
建立一個圓錐體。
建立一個圓柱體。
Draw a parabolic surface or capped solid.
建立一個金字塔。
建立頂點被平面截斷的金字塔。
建立一個中間有圓柱洞的圓柱體。
將封閉的平面曲線往與曲線平面垂直的方向擠出至邊界曲面，並與邊界曲面組合成多重曲面。
往一個方向擠出曲線。
往一個方向擠出曲面。
Create a surface, polysurface, or extrusion object with a circular profile around a curve.
將曲線擠出成曲面，再往邊界物件擠出，並與邊界物件結合。
將多重直線偏移，然後擠出並加蓋建立實體。
