Hello Frood,
thank you very much for your help and for your tricks...!!
I' got a serious probrel with scale..., I don't know where from.
at the beginning of the work of this scene the scale was good ...
as I still learn to use 3DS (it's only been a few months I started) I do not master everything.
I discovered the use of "grid" I tested some settings, maybe this is the cause ...
in the end, as long as I import an element into my scene, it is found on a huge scale ...??!!
I will look at what you notify me attentively.
thanks again.
