i wanted to start creating some new models and i figured editing existing ones was a good start.... that was not the case however... my problem is this: say that i have a fire truck where i want to cut away the "tool" part on the back and only save the cabine... how in heavens name do i do this in zmodeler i import the model that far i got it ...but it's al one big model i only end up deleting the entire truck instead of cutting away the back part... any ideas what i'm doing wrong?
