如果要搞上面那个，我会重新作，线很烂，以现在的线作也能搞出来，但没有意义，是否同感？:-O:-O作者: ouyangxp 时间: 2003-3-1 18:44

Part ...a very typical NURBS problem, in 3 sided edge problem, we make it 4, as in this case, it is a 5 edge problem, so we make it to 4 also . hope you can get what i mean .

请问你是一步把它作完的
是不是先建立小的四方面
然后用connect surfaces连接起来呢
你如何保证小的四方面之间过度光华呢
仅仅是定义边界线的端点吗？
请你们细心帮助作者: 100zhou 时间: 2003-3-3 16:59

H i,
希望你能明白，我写华语太慢了。 To get a smooth surface you must had smooth curve , the smooth curve can be obtain by watching the transition of the curvature plot of the curve, in ISDX. After create the 4 edge surface , you can connect the surface created with the neighbour surface . There will be showing a "one arrow " for tangency connection & "double arrow" for curvature connection. Of course all surface connection must had higher or same degree curve .
In this spoon seem it is simple case , you can create it in one feature . You can add draft to the spoon by setting the angle of the tangency of the curve. The typical case you can refer to the sample in PTC ISDX tutorial. Such as the "pump ", 'samsung monitor" and also the joy stick which i had upload before this . cheer, hope you can get what i mean . 作者: tony 时间: 2003-3-4 08:20
