How can i use FreeFormCloud in C#,just add one point a time?

I mean in a "for(...){}"structure,every time add a point in the freeformvolume?

I just want to add a point random in a freeformvolume,when finished a time,on the another time to add a point,than calculate the distance between this point and last point.if is <100,then creat it again randomly.

but the question is it is impossible to add point less than 1 in ffcloud

can you show me the code in C#?

Thank you very much!
