Yes I would like to combine the geometry of component 1 and component 2 into a component 3 and not having component 1 & 2 & 3 in my library, only component 3 for this example
but I dont know what to do after ''editing'' a component
there is an option, in french ''rendre unique''
just under ''creat a group''
can I use this one for make one and only one object ?
p.s. sorry but I dont remember about our talk concerning ''reversed faces''
if I understand well, ''reversed faces'' is when I copy a model and past it to the other one like a mirror ?
for example for making a bigger model I use same but smaller ones and I reverse them
but I don't see for the moment what could be the problem with that
pls can you reexplain me ?
sorry if I lost this important point
thanks
