i think that my problem, i don't know where to define the quant size since i am running it without loading a map. can i define it in SED?
No. As is said, it's not definable. You define it indirectly by scaling your models/objects. If 10.000q = 100m, and its too big for your needs, simply scale it down by 10 or even 100, so 100q = 100m. BUT: the lower the scale, the less precise your (relative) position resolution will be!
100q = 100m is almost useless, because in this case, you can only move in 10cm-steps!
