这是一个边界曲面问题,在moi中没有相应的处理工具,在犀牛中你应该使用嵌面(patch)工具,然后修剪。请看图片、gif的过程演示。
(This is a boundary surface problem, and there is no corresponding processing tool in Moi. In Rhino, you should use the patch tool and then trim it. Please take a look at the pictures and demonstrate the process of gif.)
首先需要在画边缘曲线时就保证它们是完整连接的(我在moi中提取并连接了边缘。)这一点是整个过程中最重要的(The most important aspect of the entire process is to ensure that the edge curves are fully connected when drawing them (I extracted and connected the edges in Moi))
然后使用嵌面,放样,曲线拉回曲面(gif忘了演示)修剪命令,最后join缝合在一起。实际上像这种两个曲面只是厚度的变化,不使用放样而对一张边界曲面使用偏移→厚度工具的效果更好(Then use the trimming commands of inlay, lofting, and curve pulling back to the surface (GIF forgot to demonstrate), and finally join them together. In fact, two surfaces like this are only changes in thickness, and using the offset → thickness tool on a boundary surface without using a loft would have a better effect)
当然:Michael说的也没错,作为新手,应该先学会保证绘制平面轮廓线的完整性,这需要使用修剪、join、倒角等命令,还有控制点,并熟悉它们。使用曲线本身曲度对实体切割,形成曲面。然后再学会使用放样、扫略等制作边缘形状简单更大的符合光顺度的曲面,进行边界修剪。而不是是一开始就追求空间曲线形状复杂的情况形成型边界曲面 。这时常这对软件本身难以准确计算。在达到造型要求的前提下,应尽量避免这样的情况。
(Of course: Michael is also right. As a beginner, you should first learn to ensure the integrity of drawing planar contour lines, which requires using commands such as trimming, joining, chamfering, as well as control points and familiarizing yourself with them. Use the curvature of the curve itself to cut a solid and form a surface. Then learn to use lofting, sweeping, and other techniques to create surfaces with simpler and larger edge shapes that conform to smoothness, and perform boundary trimming. Instead of pursuing complex spatial curve shapes to form boundary surfaces from the beginning. At this point, it is often difficult for the software itself to accurately calculate. On the premise of meeting the design requirements, such situations should be avoided as much as possible.)
