请教各位论坛高手！[upload=zip]non-cgi/usr/20/20_126.zip[/upload]

把surface data spreadsheet - SPECIAL - Coordinates (C)下的各个参数意义搞清楚，你的问题就解决了。

改了坐标，有2D图像，并可以分析成像等都没有问题。但是无法形成一个成型的透镜，在画出透镜元件机械iso图样时，出错，同样也无法生成3D图像。请教斑竹和高手们！

你研读下面的数据就可以明白了。

SNO1 Reversible lens having best performance in 1985 ILDC contest. It is a good
SNO2 example for sign conventions and pickups in complex systems involving mirrors.
SNO3 Note that the prism aperture is round. To make it square, you can define
SNO4 special apertures, turn surface drawing off for each surface, and draw the
SNO5 square vertices using bdi information (see pentprsm.len for an example).
