Ignoring collision

I`ve set up my enemies to collide with the environment.
I load in my enemy model and then use this to produce
the enemies within the level.
The trouble is, when I try and move my enemy to their starting position they become stuck against the environment geometry due to the fact they have been told to collide with it.
Is there a way of telling my newly copied enemy entity to ignore the environment collision whilst I just relocate it?

thanks.

HideEntity Entity
PositionEntity Entity,X,Y,Z
ShowEntity Entity

Of course! Thanks!:O)

or:

PositionEntity Entity,X,Y,Z
