ok,现在你有两个物体对吗(pic20),接下来要做的是,使用相同的方法(复制)来创建中间的一些曲线(pic21).记住最开始和最后的曲线要缩到最小.注意:如果你想闭合整个曲面,你可以使用surfaceplanar命令来闭合开始和最后的曲线.

侧视窗,创建一条参考曲线如(pic22),然后切换到顶视窗,创建一条nurbs圆形曲线(sections18)然后调整它的cv点到像(pic23)所示.记住....尽量使每个cv点之间的距离一样,因为这会影响到最后loft出来物体的效果.

隐藏参考线,再依次选择这些曲线,并使用surfaceloft命令.得到新物体如(pic26).回到侧视窗中去,创建一条如(pic27)所示的剪切曲线.

在剪切曲线仍然被选择时,按住shift键选择主物体,在侧视窗中使用editnurbsprojectcurveonsurface.你将在曲面上得到剪切曲线(pic28);选择你要保留的区域,并editnurbstrim(pic29).

现在选择主物体,按shift键选择extrude的曲面,使用circularfillet和trim命令(pic38).记住:在circularfillet一个曲面之前,打开circularfillet的选项盒并将createcurveonsurface打开,否则你将不能剪切你的曲面.next..selectouttercurve,shiftselectinnercurvethensurfacebevelplus,remember:beforebevelplus,makesuretocheckyourbevelplusoptionbox,makesureoutputoptionstonurbs.oknowbevelplusit(width0.2,depth0.2,extrudedepth0.3,outterstylecurveconcavein,innerstylecurveconvexout)(pic39)
接下来选择外沿的曲线,按shift键选择里面的曲线,使用surfacebevelplus命令,记住:在bevelplus前,你应当打开bevelplus的选项盒并确保你所输出的几何体为nurbs.ok.bevelplus的数值为width0.2,depth0.2,extrudedepth0.3,outterstylecurveconcavein,innerstylecurveconvexout.(pic39)为我们bevel出来的物品.
