Thanks for your suggestions!
- Good one, will consider this. It'll probably be added as an option in the 'Edit' menu and allow either a selection or the complete model to be put on the floor or centered.
- Going to look into this, see if I can come up with a way to give better coordinates.
- The scaling is indeed a bit broken, this is a larger issue which I'm hoping to fix.
- The .model file is human readable so you should be able to extract positions from that.
- What do you mean by taller exactly? The only constraint is the grid height (20 meters) but you can place blocks higher.
