光线控制请教

我想让0.85视场和0视场在同一个面上，并且让0.85视场的S T 相交，我使用AUTO DESIGN 不知道如何设计的
请问在设计时，使用哪个参数反映和控制场曲的呢？

需要自定义

匹兹曲率呀，好象为ptv,记不清了

AUT

@ast==(xfo fk)-(yfo fk) ; fk is indicate which field you will control the asti.

@ast=0

.....

go

<P>dfjss     </P><P>have got your answer ,i will control the ast,</P><P>but  0.85 field and 0 field  at the same plate, how to control?</P>

you can also control the xfo at axis ,use it different the xfo at 0.85Y.

...

;use above statements

@astaY==(xfo fk)-(xfo f1)

@astaY=0; because you just control @ast=0,so (xfo fk) =(yfo fk)

it 's not hard to do!

<P>  <B>dfjss</B> </P><P>because i don't know the macro language,so i think is hard for me. thank you very much.</P>

这不是宏!

you just type it in your aut sentence. it is not hard.

you also can use it in userdefined constrains. you can see it on the aut option's userdefined constrains.

If you don't know how to do ,you can read the help documents (Online Reference ) ,chapter 3.

dfjss:

thank you very much,

i will look through the chapter 3 one more time.
