codev的一般約束是不是很難控制厚度，稍微一優(yōu)化就會(huì)出現(xiàn)負(fù)數(shù) K%k,-  
，或者是說必須加入特定約束來控制嗎

@Cyqdesign，好像發(fā)錯(cuò)版塊了

已經(jīng)轉(zhuǎn)移。

個(gè)人感覺codeV 控制厚度還是可以的吧

我覺得很容易啊，一般不會(huì)出錯(cuò)的

除了在一般約束那控制外，特殊約束也要對(duì)中心厚度和邊緣厚度的控制，這樣就很少出現(xiàn)負(fù)數(shù)的了

翻閱了手冊(cè)，覺得下面的解答比較合適： :gscW&k  
On any given surface there can be only one active general thickness constraint. If on a given surface more than one of the general thickness constraints is in violation, AUTO selects the one with the largest violation and controls it for that cycle (it may release it and control a different one on the next cycle). In a zoomed system this same technique is used, although it may not be sufficient in all cases. In a “true zoom” system, this technique is sufficient to control all the general thickness constraints. However, in a general zoom system, or multi-configuration system, this technique may not be sufficient and it may be necessary for you to enter specific CT and/or ET constraints as a function of zoom position (remember that entering either CT or ET specific constraints in any zoom position disables all the general thickness constraints for all zoom positions on that surface). ,,
