The ShrinkTrimmedSrf command contracts the underlying untrimmed surface close to trimming boundaries.
步驟
4 | 選取修剪過的曲面。 修剪過的曲面是由原始曲面與修剪邊界曲線定義,如果您將貼圖貼到修剪過的曲面上,貼圖實際上是貼到整個原始曲面。有些時候原始曲面遠比修剪過的曲面大很多,彩現時會只有一小部分的貼圖出現在修剪過的曲面上。 ShrinkTrimmedSrf 指令可以使原始曲面的邊緣縮回至曲面的修剪邊緣附近,使彩現時修剪過的曲面可以顯示較大部分的貼圖。 因為只有原始曲面的大小被改變,所以修剪過的曲面通常不會有什麼可見的變化。 |
Note: Shrinking a surface is like extending smoothly, only backwards. knot of full multiplicity are added where you want the surface to be cut off. Then the remaining control points are thrown away.
The ShrinkTrimmedSrfToEdge command contracts the underlying untrimmed surface right to the to the trimming boundaries.
Shrinking the trimmed surface can sometimes cause problems later since having the edges so close to the trimming boundaries can cause commands that use the surface edges as input to fail.
與 ShrinkTrimmedSrf 指令的示範短片做比較,當控制點縮回後,它會在控制點連線與曲面邊緣留下一點距離,以 ShrinkTrimmedSrfToEdge 指令縮回控制點不會留下那一小段距離。
