Hello Chaowei.

I was having difficulty translating all of your text to English, so that I could understand your question. 

Could you please repost your question in text? 

It appears that you're asking a question related to clearance data and a similar feature for navigation in PC-DMIS.

Thanks, and welcome to the forums.  It's great to have you here.

I have too problems with translating into meaningful text.

I think on newer versions of Calypso you can not delete / not use safety plane, but you can have sub clearance planes, which are used defined.
But if you are asking about complex safety path, then it's not easy to do it right and safe.
