about mfg grid

Hi ，all
Now we use 1um technology , and the mfg grid is 0.005um in tech file.
I think it's too small for 1um technology, should I set snap spacing to 0.005 or a bigger one?
thanks for your attention and expect your reply

no one help me?

期待回答～～～

I think you can set the snap spcing to 0.005*N,where N is one integer. So you can set it to 0.5 or 1 ,and so on.

只要是0.005um的整数倍就行。
以你画着方便为主。

请问：什么是mfg?
画版图用的?不好意思，第一次听说。
