Thanks Mark - changing the settings to box really does help speed things up.

 

I think my settings in Vue are to high for my system to cope with as keep getting Vue not responding message!

Is there anyway of droping an object on the terrain in stand of to the ground - every time I import an object it seems to go below the terrain, even when I un-check the drop to ground option.

 

Thanks for your advise - really helpfull
